M3D Micro: Help recognizing burned component

Wed, 12 Oct 2022 11:20:23 -0700

Hi M3D Micro owners!

I have recently noticed one component (I think is a transistor) is burned, and I need help knowing which one it is.

I didn't find any schematics for the board, so I have no clue.

I would really appreciate any help here. I want to replace the component and fix the printer.

Thanks!

Bambu A1 Mini: Bambu Lab A1 Mini extruder clicking and filament feed issue

Mon, 09 Feb 2026 22:08:20 -0700

Hello,

I’m trying to troubleshoot a hardware issue on my Bambu Lab A1 Mini Combo 3D printer and would appreciate any guidance.

Hardware reference (for clarity): Bambu Lab A1 Mini Combo 3D printer

Issue description:

During prints, especially at higher speeds or when more filament is needed, the extruder begins to click repeatedly and the filament feed becomes inconsistent. This often results in under-extrusion or gaps in the print. The printer pauses or slows unexpectedly as well.

What I have checked so far:

Filament spool tension and re-feeding
Nozzle temperature settings
Cleaned the nozzle and heat break
Verified filament is not tangled

At this point I’m trying to determine whether this is likely due to a mechanical feed problem (gears, tensioner, idler), a drive motor issue, or a sensor/stepper calibration issue.

Specifically, I’m interested in:

Common mechanical causes of clicking extrusion on this or similar models
How to inspect the extruder gears and tension assembly safely
Any recommended checks for stepper motor performance or idler alignment

Thanks in advance for any repair/inspection advice — I’m trying to identify whether this is a hardware fault or a setup calibration issue.

Ender 3 v2 Neo: My Ender 3 Max Neo Stops Extruding Filament Mid-Print

Sun, 19 Oct 2025 02:27:46 -0700

While you may be confused why I'm putting this under Ender V2 Neo, they are functionally the same device, size being the difference. Now, here's my issue, when I print the print will start off fine enough, but filament will consistently stop at about the same point each time. https://preview.redd.it/continuous-print...

More or less what happens is that the print starts off normal, and then the print simply stops at a certain point. This isn't because the filament is caught on anything, I've had this issue for a few months and taken apart a few items of the printer. I'm not sure if this is a settings issue, or if this might be an issue with the hotend, as I had to replace it, and these problems started after a few such changes.

If you have any questions you need me to clarify, I'd really like to solve this. Thanks.

FlashForge Adventurer 3: Nozzle disconnected itself from heater/extruder during print

Sat, 20 Sep 2025 14:48:34 -0700

I replaced the 0.4mm nozzle with a 0.6mm nozzle. It printed fine for 1/2 the print and then apparently disconnected itself from the print head/extruder. It no longer seats electrically and I can't re-seat it due to the resistance from the filament. So...I can't remove it because it won't heat up due to not having any electric contact.

Monoprice Mini Delta V1: LCD no longer working

Tue, 15 Apr 2025 23:39:59 -0700

I see this is for V1, but the description acknowledges that V2 came out in 2021 so there must be some awareness of that version, which is what I have. My LCD touchscreen quit working a couple weeks back, after working fine previously. I gave this to grandkids as Christmas present, they live about an hour away, and they were the ones using it when it no longer fired up so they gave it back to old fix-it grandpa. I am pretty good tech DIY guy, so just figured I'd maybe replace the LCD and be good to go (knowing it might NOT be the LCD itself, maybe the board. connectors and power supply all look solid, though). When powered up, the screen lights, or backlights, but just a white/light grayish with no characters or graphics. That's the only way I've controlled the screen, never having used a computer or phone wifi or usb, just always put models on the micro SD card in the computer then move it to the printer. Now trying USB and wifi don't seem to connect either way, although the computer does sense via usb when the machine is powered up/connected by cable. But then neither Cura nor Weedo give me a connection to the machine recognition. Any ideas, fixes, or even where I might find a V2 LCD replacement part that's evaded all my internet searches. Plenty of used V1 machines out there that I could snap up, but that's a different animal without the touchscreen, buttons instead, and I'm just not finding anything V2 anywhere online, other than new machine at TechTitan, I think it is.

M3D Micro: Intermittent Connection and/or Extrusion Issues (?)

Fri, 25 Nov 2022 06:37:48 -0700

First, this is on a Linux Pop-OS system76 laptop (but also tested on a Dell Inspiron 17 with Ubuntu). I know the problem isn't anything like a bad cable or port, since the printer does in fact operate under certain circumstances. Here's the problem...

I recently dusted off this M3D Micro I have, the software of which was on my old Dell laptop. Except for a bad model (the .stl needed repair), the printer printed the .stl with no issues. Then I decided I should probably just put the software on my newer laptop and run from there instead. I figured out how to repair my model, but then ran into all kinds of grief trying to get the old M3D software to run on my newer system. Those issues are resolved (I think), and this is where I'm at now...

I have two software downloads:

m3drealize_1.8.2-1_amd64.deb: Printer connects but does not extrude any filament i.e. the extruder moves around as if printing, but nothing comes out. This is true on both the System76 and, now, also the Dell (re-installed the software, earlier). I've removed and reinserted the filament and it does extrude a bit during that process, so there isn't a hardware issue. It just won't do it when I go to print anything!

M3D-Linux-1.5.0.70.tar: Printer connection cuts in and out, with a message popping up every time upon re-connection: It keeps telling me that my gantrys need to be reconfigured and that I cannot print until this is done (again, this happens on both computers; I wish I had not uninstalled and re-installed on the Dell, but I didn't realize there would be any problems down the road!).

So does anyone have any idea what's going on here and, just as important, how I can go about fixing it?

Prusa i3 MK3: Turning on my Prusa i3 mk3 hotend causes printer to restart

Mon, 05 Jan 2026 02:50:26 -0700

tl;dr I have a printer that keeps restarting everytime I turn the hotend on (thing that heats the material). After taking it apart, nothing looked wrong with any wires or connections. I'm suspecting the power supply to be failing, but I have yet to check it (how would I even do that?). I want to make sure I get everything right before I go and buy a new hotend or power supply.

Hey there! I have a Prusa i3 mk3 that I've been using for quite a while now- at least a couple of years. Iirc, it has about 50+ hours of print time. For context, I am pretty experienced with these 3d printers and have a couple of years of fixing things in general. I also have all of the basic tools any good repair person would need: a soldering iron, multimeter, plenty of screwdriver bits, pry tools, etc.

Just recently, I was running a calibration when the printer suddenly restarted itself. I went to check it, and physically, nothing looked wrong. So, I decided to run the calibration again, and the same thing happened. This time, I noticed that it only happened after the hotend (the thing that heats the filament) was turned on. After manually turning on the hotend, I confirmed that it was the problem.

I found a guide on how to replace the hotend and followed it so I could get the part out. Throughout the guide, I didn't find anything wrong. There were no blown parts on the Einsy board, the wires weren't cut or crimped, and they were plugged into the right ports.

After finally getting the hotend off, it didn't seem like anything was wrong. For reference, the only things that go to the hotend are the heating element wires and a thermosister to check the temperature. The metal block looked good, and the heat sync looked perfect. There was only 1 thing I noticed that could be weird. The heater wires at the hotend kind of looked like they were touching, which could have been shorting, but they were stuck in their place when built, so nothing could have moved to suddenly short the printer. I wish I knew exactly how it heated the block, but that seems like it probably isn't the problem.

I then unplugged the heating element and not the thermosister, set it to turn on, and it didn't immediately restart. This tells me it isn't a software issue with the thermosister saying that the printer is overheating (again, the printer would restart as soon as the temp was set, not after a few seconds of heating).

My main (and honestly only) suspect at this point is the power supply failing. Is there a way to check if a power supply is failing or not? Or is there something else I should check/do that I haven't done? I want to make sure I know what the problem is and if I can fix it before I go replace the hotend or power supply.

Sorry for the long read btw. I'm happy to give more details if needed. Any responses are helpful!

***

Update: After opening the bottom part of the PSU, the part with all the screws holding the wires in place, I can confirm the the PSU is not the problem. When I turn the hotend on, the power LED does not turn off and then immediately turn back on, it stays on. This means that the PSU is not suddenly shutting down when under load and then causing the printer to restart. This is kind of annoying, because it means that the problem very well may be the hotend.

3D Printer: Why is my extruder nozzle not heating?

Sun, 26 May 2024 14:01:20 -0700

I have a MP Voxel 3D printer. After a ten hour print I switched to some small fifteen minute prints. After a couple of these, all of a sudden, I’m hearing these strange grinding noises. Turns out it was the feeder trying and failing to feed the filament because the extruder wasn’t melting the filament. I’d only taken a couple of minutes to remove the plate so I could remove the print. Everything else works, just not the extruder. What happened and how do I fix it?
