Using an Anet A6 3D printer in the UK... (mains voltage issue!) | The UK uses 230 V mains voltage. The 220 V designation is from the past, Europe is now using 230 V. You do not have to worry about the frequency.
You should place the switch to 220 V and plug the cord into the socket. The printer should start immediately booting (cycling) the printer firmware, the ... |
Can I really throw failed PLA prints on compost? | This question has been asked on just about every forum out there. Here's one example from filabot.com .
The reality however, is that this process will take several hundred
years in a typical landfill. To biodegrade, PLA requires a laundry
list of conditions to effectively break down. Specifically - oxygen, a

Delta 3D printer extruder? | My FLSUN Kossel 3D Delta printer ($224) has a bowden extruder. It works really well too.
The main advantage of having one is that it reduces the mass of the hot end. That means less inertia, and it's easier on the driver motors as well. All this leads to (hopefully) greater and more precise control at the extruder tip... |
Finding a shredder for my failed prints | there is a project called precious plastic and there is a plastic shredder, but it is a rather expensive solution.
As I am waiting for parts for my Lyman extruder, my plan is to hammer the parts and then process in old kitchen robot with steel working area, an example here
The paper shredder will be ok as long as you... |
Will this MOSFET allow the heat bed to run at a different voltage than the control board | Short answer YES. You can run it from a different power supply at a higher voltage. Also it has a PC817 Optical isolator (for some reason) therefore the second power supply and your main board should not be electrically connected at all. |
Z-axis of Anet A8 always moves additional 5 mm upwards when moving X and Y-axis in Ultimaker Cura | Answer taken from OP's question
(24.01.2019) UPDATE: I updated Marlin to 1.1.9 and used the configuration from repository. Since I also printed a new print head (for Bowden extruder) I had to rework all offsets. Same time I switched to Simplify3D (cause I need better control for support blocks). Since then the probl... |
Beginner FreeCAD question on axes when sketching | This answer assumes you're working in the Part Design workbench.
So you want to adjust the starting height of a pad or pocket. There are two ways I can think of to do this easily.
Adjust the Z attachment value of the sketch to lower the sketch below the surface.
Use the "two dimensions" option in the pad/poc... |
Skipping Y-steps, only when using Ultimaker Cura | You answered your own question in a comment.
Yes, of course, increasing the maximum supplied current to the motor gets rid of the issue. Still, I'd rather go with lower current to limit heating up the motors. I was just wondering if there is something in the two slicing engines that makes cura provoke much harsher ... |
I am using a stereo 3D pen. What surface should I use? | You could use a piece of glass, that's what most people using 3D printers have as a build surface. An easy source of glass for pen use would be a picture frame but the edges are likely sharp so be careful. Acrylic would also work and is easily obtained in small pieces from places like Lowes/Home Depot, I used Acrylic... |
Is there a slicer that can set the print speed for each layer as a function of the layer area? | Most slicers have a feature in their cooling settings to "slow down if layer print time is below xxx".
Setting this to a higher value should ensure that small / short layers aren't printed too fast, so that cooling is still reliable.
Shorter layers are slowed down linearly to reach the specified minimum time ... |
Upgrading to silicone heat bed, will it burn my house down? | The heated bed port on your board has a 11A fuse. It will not work for a heated bed requiring 16A of current, no matter how good the MOSFETs might be. Note that the terminal block might also not be rated for that much current. You'd have to check, because often it is not the MOSFET itself that catches fire but the wiri... |
Change Slic3r settings for left handed coordinate system | The direction of the end stop is set in the firmware of the printer. Even with different setup end stops, you should be able to get a correct coordinate system without mirroring axes in slicers. This would be the preferred method to fix your problem!
E.g. my Ultimaker 3 Extended homes the Z on Z max having the platfor... |
Labists ET4 printer nozzle hits bed after automatic levelling | Dirt. It was dirt. Most likely.
Apparently the machine establishes bed level with a sensor, and I might be wrong, but I think the ET4 monitors capacitance as a means to notice how far the nozzle is from the bed.
After all else failed I looked at the nozzle closely and noticed that the whole thing looked fuzzy. Looks l... |
TEVO Tarantula under extrusion | Summarizing for correct understanding: you measured 100 mm without the hotend heated and attached and about 50mm attached and at temperature but not hearing any clicks using a pretty long Bowden tube?
Bowden setups require a little more torque to push the filament all the way to the hotend. I've experienced this with ... |
Power supply not working | I would expect the root cause to simply be the power supply itself.
5 Ω is a reasonable resistance for a 12 V / 30 W heater. It seems strange that you are not seeing continuity in the heated bed as this should also have a low resistance (since it's a heater as well). This might be worth investigating further... |
PETG grinding with direct drive extruder | This does sound a lot like you are experiencing the effects of heat creep (How is heat creep characterized?). You should lower the temperature of the hotend and increase the printing speed and retraction speed and possibly lower the retraction length.
If this is heat creep, a new extruder will not help you until you s... |
Replacing jerk with ridiculously high acceleration? | In order to evaluate whether this is possible, it's necessary to realize that following a curved path with zero jerk (in the classic jerk sense) requires stopping and restarting at each junction point in the piecewise-linear approximation of the curve that occurs in the gcode. This is because there's no way to accelera... |
Irregular 3D printed part | Your print isn't cooling fast enough. With small, thin prints like this, PLA needs a fair bit of airflow to solidify before the next layer goes down. Your printer doesn't appear to have a proper print-cooling fan, so I have two suggestions:
Print two or even three of the part at the same time, spaced a fair distance ... |
Home-brew alcohol to clean resin prints | Isopropyl-Alcohol - Propan-2-ol - and Ethyl alcohol - Ethan-1-ol - are different chemically. As a secondary alcohol, Propan-2-ol has quite different solubility of different materials than ethyl-alcohol.
Now, let's look at home made alcoholic destillate. That stuff is, if done in one refraction and without tossing the f... |
OctoPi command v412-ctl not found | It's an l (ell) not a 1 (one). v4l2-ctl. |
Which connectors should I use to connect my Power Supply Unit to the Ramps? | You're quite right :)
L (AC): Brown colour. Single Phase line or Three Phase Line (L1)
N (AC): Blue colour. Neutral
GND: Green and yellow colours. Protective earth or ground (PE)
COM: DC Negative (-) - Also referred to as "Common"
V+: DC Positive (+)
V(ADJ). This is for a potentiometer, in order to modify the outp... |
Is there a method or S/W available to stitch together a DLP projector's output into a "moving picture" to SLA print in a larger area than its output? | Cool Idea.
I know using a projector sounds like solution; but, I in practice, think it is going to be difficult.
My concern with trying to use a projector would be two-fold.
It would have to project on a large flat surface. Since basic optics wants to focus on a sphere, when projecting on a flat surface you have... |
Are stepper flex couplings important? How important? | Yes and No
Let's start with the obvious: Flex couplings or rigid couplings are a deliberate choice in designing the printer. Each has its benefits and drawbacks. So let's look into the 4 types of drive-train setups that I know to be possible:
Spiral couplings make it possible to operate the machine with a slightly mis... |
Cura imports FreeCAD stl wrong | I suspect that your method to create the hole for the pins may not be consistent with the modeling practice that FreeCad and other programs of this nature require.
Consider the following:
Import your base shape.
Create a second shape that matches the hole you wish to create. It must be a solid object, not a plane or ... |
Delta printer printing incorrect dimensions in X and Y directions. Z dimensions are correct | As detailed at minow.blogspot.com (which I found very helpful for the most part - it was the first link in the answer to my related question) you need to check/adjust the zero in front of each tower, check the zero in the center, tweak the radius, and repeat (checking the zeros at the edge of the bed in front of each t... |
24 V heated bed from -12 V and +12 V ATX power supply? | No, this is not possible with most ATX power supplies. While in principle you can get a 24V supply by combining the +12V and -12V supplies, the rails are not symmetric, and the negative 12V supply is usually designed for a much lower load than the positive supply. In the example in the following picture, there are two ... |
New PETG spool from eSUN is making popping sound while extruding | The extruder can't hold much water and transport it to the melt zone. Filament can. The printer behaves like the filament is wet, so try drying it.
Try putting the filament in your electric oven at the lowest temperature (often 170 °F to 180 °F) for an hour and see if the behavior improves.
Kee... |
Object's height not a multiple of layer height | Slicers will round off to the next nearest layer, so 20.2 mm in your case. However, you can get to 20.1 mm if you use a 0.3 mm first layer. |
What do I need to know to successfully use Taulman/Dow EVOLV3D™ USM Universal Support Material? | Advice From Taulman
On emailing Taulman asking for advice (after getting some initial failed prints), they responded with the following:
[...W]e use the following settings. Support:
Flow 115 %
Infill = 8-10 %
2 full surfaces at 100 %
Support speed 50 % of print speed.

Proof that Slicing Plane/STL intersection will only produce Closed-Loop Polygons? | You can't prove that because it isn't true. An STL file is just a collection of triangles. There is no guarantee that an intersection with the slicing plane will consist of closed-loop polygons. To be suitable for 3D printing an STL file should represent one or more closed, disjoint polyhedra (which would yield closed-... |
What is the reinforcement for 3D printing concrete cement? | There is no reinforcement. You can use this ‘printing’ solution for walls but by default not for floors. There are experiments that use the solution to span a gap but they use relatively thick plates.
For example, see this paper, Design of a 3D printed concrete bridge by testing. |
Loss of extrusion in Stratasys FDM liquefier | This isn't a "turn this knob and all will be well" answer, because your machine setup sounds pretty unique to what most people will have experience with. Not being familiar with the older Stratasys printheads, but based on my overall experience with 3D printers, there are three things that could be an issue:
The nozz... |
Is G-code read line by line? | Yes, G-code is read line by line. G-code is a numerical control programming language. It basically instructs the machine sequentially line by line to do a specific task. The printer than executes the lines one by one until it reaches the end.
If you instruct the printer to wait (G4 dwell), it will do the wait/dwell fi... |
Problems with elephant's foot | Elephant's foot can be caused by different causes.
Incorrect leveling or incorrect nozzle to bed distanceThis answer describes that it can be caused by a too low nozzle to bed distance.
Bed temperatureA too high bed temperature and weight of the print can cause bulging out of the bottom layers. This also frequently oc... |
Finding the right material to print RC CAR cover | I have 3D printed models which were then sanded using progressively finer grades of sandpaper, terminating with wet sanding using micromesh to 12000 grit. The result was smooth and shining without any coating applied.
If your original results were not acceptable, the process may have been flawed and should be re-consi... |
How can I make bed leveling improvements in the middle of my Ender 3 V2 bed? | The gaps are, because the nozzle is to far from the bed at this point. It may sound like a big deal, but actually this is not leveling alone, but it looks like the bed is not a perfect plane/perfectly flat. This is normal, my ikea mirror and my stock bed show the same thing. Now here's one solution:

Why all the excitement about linear rails? | The following is a compilation of the input from a number of sources.
Linear rails in general are mechanical components that - when designing equipment - offer great flexibility.
The profile of the rail can be designed in nearly infinite ways. This in turn allows for:
Different levels of stiffness in different dire... |
Printing files over USB drive (Ender 3 Pro) | Unfortunately, no.
There are two types of USB devices: host, such as a PC, and device, such as a thumb drive. (Actually, there is a third type, on-the-go, which can act as either.)
The Ender 3 mainboard is a USB device which means that it can only connect to a USB host. You cannot directly connect two USB devices, such... |
Replacement Z Probe for MP10 | From Thingiverse you can find a BLTouch mount for the MP10 (and MP10 mini):
Note that in order to use the BLTouch sensor you need a different controller board that supports connecting a BLTouch sensor as the MonoPrice controller board doesn't support connecting a BLTouch sensor.
From ref.:

Installing multiple versions of ChiTu side by side | Running multiple versions of the same software did not sit well with the software person in me, so I dug a little deeper.
ChiTu has a "settings" button to the right side, and under that section it is possible to configure different, separate printer profiles. That may take care of the differences if properly ... |
Anet A8 stock replacement fuse between motherboard and PSU | Couple things to note.
First one is that as @Paulster2 mentioned, the fuse itself should have its rating printed on it.
Second one is that if your fuse blew, there's a reason for that, and you really should try to figure out what that reason is before you start putting fuses back in. The Anet A8 isn't exactly what I'... |
Brim around just one section | I don't know a way to do that with Cura without breaking it up into multiple parts with different settings for each, but what about just enabling supports? You'd only get a very small amount of support material and it would act similarly to a brim to keep the small part from detaching. |
TMC2130 External VM RAMPS 1.4 | First of all, I'm not talking on a first-hand experience: I don't own a RAMPS based printer.
If I were you and wish to be 100 % sure the setup you are describing doesn't blow up in my face I would use a spare pin on the Mega to drive the relay which, in turn, drive the 24 V source line. In terms of delay I would use a ... |
Delamination issue Ender 3 Pro PLA | This is under extrusion, not delamination. Delamination is the result of the under extrusion.
It typically happens when the wrong filament diameter has been set in the slicer (a larger diameter than used, e.g 2.85 mm instead of 1.75 mm). Another option is that you accidentally put the printer in volumetric printing mod... |
Why does the Ultimaker 3D Printer has a Heater + Heater transfer plate (aluminium) + Glass? | According to this page, heat transfers more evenly across an aluminum build plate than with just glass. But as Kevin pointed PLA adheres better to glass because it doesn't flex as much as aluminum under heat.
The link above shows that aluminum has a much higher thermal conductivity at 205 (W/(mK)) vs glass at 105 (W/(... |
Printer fails to print a cube | There are multiple issues that cause this result.
First, your nozzle is to far from the bed. This can be seen by the curly deposited filament on the build plate (I guess that is the brim or the skirt). Please properly level the bed and position the nozzle at a distance of a plain A4 paper as best as possible (should b... |
Filament is stuck in nozzle | There are a number of options you could try. If heating up the hotend does not work, you'll have to disassemble it. Remove the nozzle and the heatbreak (the threaded part). To disassemble the nozzle, you will need to heat it up and use pliers or wrenches to unscrew the parts.
You can use a blowtorch to melt and burn ... |
What am I doing wrong with my M3D Micro? | It's not you - it's the printer!
The M3D Micro is not a very sturdy setup. The X-axis is a single pair of thin rods, hung up on a pair of similarly thin rods in Y and mounted on 3 very thin pillars in Z. While the idea is good, the execution is not particularly well: The rods are too thin and the design is virtually un... |
Can the resin from Resin based 3D printers be used to make printed circuit boards? | Brushed aluminum is a common bed surface for resin based printers. The aspect of the aluminum that is important to the print is the adhesion, hence the roughness of brushed aluminum. It has to be sufficient to hold the print in place, but not so extreme as to cause destruction on removal.
In the case of copper as a pr... |
How does wireless 3D printing work? | Slicers don't talk to the printer. Slicers analyze an STL file and generate a GCODE file, based on your parameters. A print manager sends the commands from the GCODE file to the printer board, which executes them sequentially.
They are not. Commands are sent to the printer from a print manager of some sort. This varie... |
How can I run two instances (or equivalent) of Slic3r on OS X? | You could duplicate the application by clicking on the application and pressing Command (⌘) + D, and then run both - although I'm not sure if that would mess with the preferences. I haven't fully tested it, but both instances opened up and worked, seemingly ok.
You could even rename them to something other than "Sli... |
Upgrade hot-end to achieve higher temps (e.g. for PETG) | Most PETG reacts vey badly to temperatures above 255. The typical optimal PETG temperature ranges from 225 to 245. Above that it gets sticky...
If PETG is your goal, you might want to find a filament that is more friendly to your printer. They are pretty cheap, and now you have transitioned to an all-metal hot end, yo... |
Why is CLIP so much faster than SLA? | It's important to understand what specifically is being compared. CLIP is much faster than bottom-up technologies that require a peel step between every layer. For example, the Form1 galvo SLA printer tilts the resin vat to separate the transparent bottom from the print. That is, by far, the slowest part of SLA/DLP pri... |
Where to define grid for bilinear levelling in Marlin | If you have managed to setup 3-point levelling, you should be able to enable bi-linear levelling in the firmware.
From the configuration.h file for Marlin firmware you can find the following options:
/**
* Choose one of the options below to enable G29 Bed Leveling. The parameters
* and behavior of G29 will change ... |
Controlling a 3D printer with another Arduino device over serial | This isn't really a 3D-printing issue as much as it is about Arduino, USB, and how serial connections over USB differ from a generic UART serial connection.
For a UART-based serial connection, there are only two devices, and both devices are peers - either can send data to the other with no real restrictions as long a... |
Extruder Clicking without Extrusion Problems | Even though you may have acceptable extrusion, any clicking from that area of your printer is likely to be a missed step on the extruder motor. This may be insignificant with respect to print quality, but as you suggest, it is an irritation.
If you are confident that your nozzle is clean of debris (which is likely), y... |
Extrusion test cube resulted in one wall being thicker | Why not that test print?
You don't want a print constraining your walls to 0.8 mm, since you don't want to print with 1 nozzle diameter for better print quality. Atop that, slicing can induce errors that increase the thickness of walls without us noticing it in the slicer view. Two sources of error (once for each wall... |
What is the best way to build a closed loop continuous rotation servo for 3D printer? | You can use a magnetic position encoder.
AS5048B High Resolution Position Sensor
14-bit rotary position sensor with digital angle (interface) and PWM output
14 bit means 16k steps/rotation. With a stepper which does 200 steps/rotation and 16x microstepping, you will need only 11 bit, so you have plenty of extra accurac... |
Prusa MK3S 0.8 mm nozzle layers separating | After printing ~30 calibration test cubes I finally figured out the perfect settings.
Apparently, the extrusion width in my slicer was set to a certain number, instead of
percentage. I was printing at 0.45 mm extrusion width, which was ~105 % of the 0.4 mm nozzle diameter, but less than 50 % of t... |
Tuning line width and flow compensation in Cura | That is very bizarre. Since GCODE describe each movement of the printing head (so, the printer does not get to decide anything in terms of printing strategy, it just executes), I can only see three possibilities that would explain what's going on.
The print is being scaled up at printer level. This could for example... |
What is the thinnest hotend? | The size of the nozzle usually isn't the main factor for how close you can put nozzles together. To keep the filament drive gear system from being the limiting factor, you would need Bowden extruders. "Then, the heat sinks and fans would be your limiting factor. Have you considered a single nozzle with three ext... |
Filament that will not stick to wood glue? | You are looking for a filament that does not bond to wood glue, or as weak as possible. You misunderstand how wood glue "bonds" to plastics:
Wood glue is typically PVA. It bonds to wood and paper by seeping into them before curing and hardening. The mesh of the glue entangles fibers of the wood/paper and itse... |
Designing back plate for Ring Doorbell | If you wannwa go fully parametric, use OpenSCAD. Or you can use Autodesk Fusion 360 (which is free for non-commercial use) |
Printer changing temperature after selecting file | The demo files are gcode files generated for use with the sample PLA that comes with the printer. If you want to print it with ABS select the file and set the temperature manually afterwards. |
How can I add an offset to the first layer to increase clearance? | Placeholders
I don't know if you are familiar with the concept of placeholders? PrusSlicer is a derivative of Slic3r which uses this concept to insert placeholders (sort of constants, with the possibility to do arithmetic) into your G-code (e.g. start or end codes) which are evaluated just before the slicer generates t... |
How to make it so that multiple motors respond to | One way to have two E-steppers to do the same work should be to enable MIXING_EXTRUDER in Configuration.h. I have no experience in this myself, but it is a good starting point.
A second way is to actually connect the two identical steppers in parallel. That trick is sometimes used for Z-steppers. I don't expect the cur... |
Prusa I3 - Burn marks on print | I have seen this after I reassemble the extruder heat block and then leave it too loose during the print.
Is your extruder above the nozzle coated in a brown or black film?
What happens is the liquid plastic oozes through the loose connection, travels around the outside of the block, where it is heated longer and hot... |
Lack of isolation between axes | This is easily explained - it's the stepper motors getting powered up. Stepper motors even if not moving are constantly powered up and actively hold the position they are in exactly at the stepping point where they are.
If you power down the machine or if the board disables the stepper drivers to save energy or becaus... |
Converting a mesh to constructive solid geometry | The calculations for your objective could be considered simple geometry, although the results in terms of formulae are a bit more complex than simple, but not by much.
According to Quora, the foundation for this goal is that the cube's eight vertices will be coincidental to the sphere's surface. If one desires to prin... |
What is the benefit of using an ARM based electronics? | 3D printer controllers have to do a lot of stuff very, very fast. Performing kinematics and dynamics calculations while sending many thousands of precisely-synchronized step pulses per second is really, really hard. The 8bit AVR line of microcontrollers used in older 3D printer controllers is basically a late-1990s era... |
Printing with colorfabb XT fails after several successful layers | This looks a lot like under extrusion caused by heat creep.
Heat creep is when the nozzle temperature 'creeps' up through the filament and makes it melt (a bit) and form a blob (or just widen enough to get stuck) a centimeter or two before the nozzle.
The characteristic is usually that everything works perfectly well... |
Why is it conventional to set line width > nozzle diameter? | There are several things at play that can make a wider line nice to have:
First layer adhesion
Due to some filaments having serious struggle to get the first line or layer stuck to the bed, it can be an easy fix to just increase the line width, generating a bigger Adhesive Force $F_a\propto A(l,w)$, where A is the area... |
My nozzle on my Ender3 V2 is higher when it is printing than it is when I auto home it | From my experience Auto Home procedure rearly leaves Z position at 0. By default Marlin raises it to 4 mm above the bed as far as I remember. The same might be with Z offset.
Also, could you please check "Initial Layer Height" in Cura?
Could you check the machine's "Start G-Code" for presence of G91... |
Advantages of GT2 over a rack | With a belt system, the belt engages roughly half the pulley. This, and the tension in the belt, ensures the belt always engages the pulley tightly. A belt and pulley system is thus relatively forgiving.
With a rack and pinion system, only a few teeth engage at any given time. To avoid backlash and get the same kind o... |
DIY tensile strength testing | For these kind of tests you could rely on the ASTM standards. They define test procedures and test specimen sizes for different types of tests. Or you can derive a specimen yourself based on these standards (e.g. for my bachelor's degree I used an alternative notch impact specimen as I was bound to the amount of availa... |
Ultimaker Layer Resolution vs Nozzle Size | You need a certain minimum flow rate to achieve consistent extrusion. Flow rate is the product of print speed, extrusion width (proportional to nozzle size) and print speed. If you use a very small nozzle and very low layer height, you'd need a very high printing speed to achieve a reasonable flow rate. Therefore, it's... |
Problems with stock gear with no screw on Ender 3 pro | This is an older Ender 3 Pro, they at one point came with these press-fit gears, these are not intended to be removed which is a poor design decision. I would recommend buying a new motor than going through the hassle of removing it. |
When leveling hotend always slams into bed? | I realised the simplest fix for this shortly after posting the question. In either your slicer or your printer controller (I use octoprint, so I added this there) add to the starting G-code something to lift the head so that it is above the point it is scraping across.
For example, change your starting G-code from som... |
Easy way to refine a 3D-model for 3D printing by removing internal geometry | About 10 minutes after writing the question, it suddenly dawned on me, that I was not using Meshmixer to its full potential, and especially not a simple property of Cura:

Filament not extruding | The spindle screws on the gear are shipped not tight enough. Try taking the fan off and make sure the gear is seated properly and tighten the screws down. Here's a video that might help. https://youtu.be/zkZKzF3J3NA |
OpenSCAD "not valid 2-manifold" useful information | Occasionally, a model created in OpenSCAD will have, as you suggest, overlapping segments. Often enough, this will generate the message you receive. OpenSCAD has an implied union function when it comes to independent objects, but if you wish to clear those errors, experiment with explicit union statements where you hav... |
How does an H-bot printer work? | The CoreXY kinematics can be seen as an evolution of the H-bot kinematics. In Marlin, you both need to configure the printer as a CoreXY machine. Note that your steps are determined by the pulleys in the steppers and need to be the same for the steppers. With testing you will find out if you have the correct value.

Ready to use objects instead of 3D-printing them | If your printer is reliable enough I would suggest printing multiple parts in one go. Since the cylinders are only 12 mm in diameter you can easily fit over a hundred of them on a standard 20 x 20 cm built plate with a couple of millimeters spacing in between. |
Which digipot is this with the markings "AAJU" | The picture shows, that the marked chip is next to the letters U8 to U12. U is commonly used for Ineparable Assembies, but there are several meanings possible according to the ANSI/IEEE Std 315 (1975). So, let's assume for the moment that this is Assembly 8 to 12.
Note that the X-pot is marked to be down on the right s... |
How do you calibrate a delta robot 3D printer? | This answer below is (partially) taken from my answer to Delta printer nozzle not moving square with a perfectly level bed (as if the bed is bent... but it isn't).
Whilst the answer below is for a Kossel, assuming that you are using Marlin, then the process should be more or less the same.

MK8 extruder showing 500+ °C on temperature sensor? | A brand new thermistor shows about 95-105k ohm (depends on the multimeter quality), so it looks like that one is out of the range.
To be sure that it is a thermistor, you could connect a 100k potentiometer, play with it and see readings on the lcd. If the readings are OK, then mainboard is good so replace the thermisto... |
Issue with Z homing on Ender 3 Pro with Marlin | I've actually found what the issue was. It turns out that my Z steps were way out of whack (i.e. 4000 steps/mm instead of 400). Apparently, that's the default value in GitHub for version 2.0 of Marlin. Not sure if that's a typo or a valid value, anyhow setting it to 400 fixed it. |
How to interpret various thermal-related filament properties? | This depends on application.

Why can my printer display remaining time but OctoPrint can't? | Octoprint is a generic application that has to work with a rather wide variety of printers and printer firmwares. The time estimation that is shipped with Octoprint by default is a very basic method that doesn't rely on any specific printer features. This also makes it kind of useless in some cases, and not very accura... |
In FreeCAD, how do you copy a sketch from one plane to another? | I’m assuming you are working in the Part Design workbench. Select the sketch and click Edit->duplicate selected object. Make sure that only the sketch is copied (depending on the version, either deselect the plane or click don’t include dependent objects). This will produce a duplicate sketch in the active body (if ... |
Snapping to Ground - 123D Design | The position matters a lot if you use the default STL file without doing anything in the slicer. I've used 123D extensively and when I've inadvertently left a gap between the part and bed (and not snapped it to the bed in the slicer), the printer tries to print in mid air.

Weird temperature reading using thermistor on MKS GEN L v1.0 AUX-2 analog pins | Thermistors, commonly used as temperature sensors on 3D printers and other DIY things, work by changing their internal resistance depending on the temperature.
On the analog ports, the microcontroller can determine the voltage of the connected signal.
To actually measure the resistance - and thus temperature - of the... |
Bowden setup keeps jamming between PTFE tube and heatsink | Filament sometimes get stuck on the rim of the PTFE tubes inside the heat sink. Josef Prusa from Prusa Research has published a document on how you should chamfer the PTFE tubes for his printers:
Maybe chamfering your tubes works for you too. |
Is it practical to build a separate hotend temperature controller to assemble hotends without taking up printer time? | You can get a suitable board for $20 or so, print a case for a few cents, and either repurpose an old PC power supply or buy a new one just powerful enough for the hotend (not bed) heater very cheap, so I think it's a lot less costly than a cheap printer, and cobsumes less space. But I'm not clear what you need it for. |
Can commodity 3D printer extrusion hardware and filament be used for injection molding? | Injection molding requires two major components: pressure and heat. So your question can be broken down into those two halves: can your average extruder handle injection molding temperatures, and can it handle injection molding pressures?
Let's start with pressure.
Per this page on the University of Minnesota's site, p... |
I need assistance replacing the PTFE tube in the nozzle on our Flashforge dreamer | I got the same issue before. When you tried to push out the material from the tube, one end of the tube was being pressed. The tube was so soft that the diameter at that end was slightly increased. Hence it was difficult to put the tube back. When you tried to tighten the screw, more force applied and the tube end was ... |
Resin printing on Voxelab Polaris | If you want to print flat, you could easily print all parts at 90 %: the bounding box dimensions now are 81.16 x 88 mm - and as a result, you can print some other parts flat next to it but not more than one tile at the same time. Remember to print all cities and roads at 90 % too. |
How to use a 3.8V stepper with Marlin / RAMPS? | The 3.8 V rating does not mean what you think it does. "Rated voltage" has a very specific technical meaning. For a 3D stepper motor to work properly, the rated voltage of the stepper motors actually needs to be significantly lower than the supply voltage of the stepper drivers.
These steppers are perfectly compa... |
can the intel sense "xyzprinters 3dscanner" work on amd prossessors anyway? | Here are some ways a program might indicate incompatibility:
There is something in the code that is actually incompatible -- such
as some Intel-only DSP instructions.
They are using an Intel library or source code that is licensed only for
use on Intel processors.
They added a check to their code to be sure the pro... |
