MPCNC randomly wrong milling paths
I have a problem. I own an MPCNC that has dual endstops and is controlled by a RAMPS board with Marlin firmware (V515 Marlin 2.1.1).
I use the Estlcam 11.244 software in combination with Repetier Host.
The whole setup works properly and can mill fine.
But now, while milling a random letter, he suddenly wants to choose a completely different route and suddenly starts milling a lot deeper, causing the project to break.
I have already tried the following:
- Other Marlin firmware
- Other speeds
- Print via PC or via SDCard
- I thought maybe I hitted the endstops but even that wasn’t the problem
Yet he continues to do this completely arbitrarily.
Anyone any idea?
In my latstest mill project what went wrong, Repetier Host showt the last messages:
10:35:38.305 : N3061 M140 S0*81
10:35:38.689 : echo:Unknown command: “M140 S0”
No idea if that has anything to do with it.
NOTE: Some random letters work perfectly, but even if i start them again it could break/crash.
Thanks for contributing ideas!
