I wonder if they switched to using whatever is in the M3? It might be worth looking on github for the M3 clamp files.

I've just finished calibrating Input Shaping and Junction Deviation. Orca Slicer makes it super easy to calibrate for a lot of different things. I've only got a couple meters left on this spool of PLA, and I will be switching over to my normal filament, which is 3DFuel's "Tough PLA+". Then I get to ...

I'm making progress... I have a model I recently printed using S3D, and using Prusa Slicer. It's a small thick walled cylinder with a dovetail stuck on one side. The S3D print came out pretty clean, but the Prusa Slicer one is FULL of stringing, despite telling it not to cross open spaces. I set it ...

I've been chasing down how to calibrate the "K" factor for Linear Advance now that I've updated the Marlin firmware in my M2E printer. One article I ran across mentioned that OrcaSlicer has an entire suite of built in calibration tools, including for Linear Advance. I dug around in the OrcaSlicer gi...

I finally found time to learn how to upgrade my firmware by coming down with the flu... Sitting at my computer for hours was about all I could manage. I now have Marlin Version 2.1.2.5 running on my M2E. Mine printer is a 2917 version, with the Z-stop at the bottom, 24V power supply, and the Geeetec...

I also have an M2E. The one upgrade I think is really worthwhile is to get a controller with Linear Advance. This is supposed to give a big improvement in print quality. To use the existing hardware, you need to update the firmware to Marlin 2.x. I haven't done firmware programming in about 40 years...

If the machine is that old and has been used heavily, I would suspect an intermittent connection in the wiring harness. On the other hand, I don't know enough about stepper motor drive connections to see how it would reverse direction occasionally...

Thanks! I'll have to add this to my notes. I got it working a while back, and someday I will want to add some macros to help do things like change filaments. For now, I'm too used to the old Simplify 3D control interface, and I just use that. For a long time it wasn't clear if S3D was going to survi...

MakerGear does have a beta version of Marlin 2.1. I downloaded it about a year ago, but I had a few issues I wanted to fix/investigate, but got tied up with other stuff. They may have a newer version by now. The things I ran into were: 1) All my motors run backwards. Their recommendation was to open...

As you have discovered, this forum is pretty quiet. Unfortunately, I have a single extruder machine and can't provide any assistance. Your best bet is probably to contact MakerGear factory Tech Support. They've always been helpful when I've had a question. The other thing might be to track down the ...
