Bed height map tool reseting, restarting or rebooting printer

Hello All!

I'm running the bed height map tool but it nearly always resets the printer after probing a few times or half way through. In other ocassions Repetier Host crashes and closes.

I've tried Ascii and binary modes, changed receive buffer higher and lower, faster and slower speeds, a fresh windows 10 install on a separate laptop, tidied all wiring and separated power and signal cables...

Any ideas how to troubleshoot this issue? The printer restarts, drops the hotend a bit and continues without homing.

  • You are using a unknown firmware, guess the modified repetier firmware from cnc. Resets come from firmware side I guess and you should see the log for the reset reason to know more. Could be external reset, watchdog or brown out.
