I decided to try and decipher the OpenSCAD model and came up with this model that isn't full detailed but should be sufficient for anyone trying to design mounting provisions above an extruder.

It looks like the SD card managed to corrupt itself. We managed to recover most of the data on it but had to recreate the config.g file.

Lesson learned to keep good backups and perhaps the SD card is due for replacement.

We were adjusting the Z-offset value for the BLTouch probe in the config file when upon rebooting the mainboard the PanelDue went blank and DWC would not connect. I can connect through pronterface but the Duet will not respond to a ping and the PanelDue is just black (backlight is on).

I have tried the following so far:
Verified the SD card using M122 and M39 and M122 P104 S10. All worked fine.
I checked the diag LED, it comes on for about 0.5 seconds as expected and goes off. All voltage LEDs are lit as well.

I think I've exhausted all of the troubleshooting steps I found on the wiki. Any ideas?

Thank you,

@OwenD I do have bearings on my filament spool. The issue is getting the spool moving each time the filament retracts and then pulls again.

@dc42 I am using 3.3. Perhaps I should try the 3.4 update?

Anyone?

This issue stems from using 10kg spools with this printer and the initial inertia of getting the spool rotating trips the filament sensor. I'm open to other suggestions on solving this.

I've noticed (at least for my printer) that about 90% of filament too little movement errors can simply be resumed and the printer keeps working. My thought is to create some conditional G code that will automatically resume the printer once. If it pauses again within 5 seconds or so after resuming, then it will stay paused. If the printer keeps printing after auto resuming, then this cycle can reset and repeat for future errors.

However, I'm not much of a programmer and am trying to figure out how to implement this. I'll have to initialize some variables in my start G code and I imagine filament-error0.g will have some sort of test to see whether it has just paused within the last 5 seconds or so.

Any suggestions would be greatly appreciated!

I'd love to see this implemented. I have a Modix printer that uses Duet hardware and prints are regularly 24 hours or longer. Being able to set up preventive maintenance based on clocked print hours would be extremely useful. All of our other printers have this feature! (Craftbot, Flashforge, Stratasys)

@zapta Yes kind of - some connectors are ultrasonic welded.

Most definitely not something available to the hobbyist nor necessary for a 3D printer.

Pretty cool process nonetheless:

@t3p3tony I see that. Attempted to go through FreeCAD to get a .step file but that's proving tricky. Looking like I'll reverse engineer it from the .stl file and remake it in SW.

@thatninthguy Thanks but I need the magnetic filament monitor version. I'm trying to incorporate solid mounting for it in an extruder bracket im designing.

I could use the .stl files but SW hates modelling with meshes.
