M280 Invalid Servo Index 0 in M280 Command



  • I'm getting this error when homing. It was working fine before. Yesterday I set it up to do sensorless endstops for X Y, and it started with this error. I returned all of my sys files back to the original and it was still happening. I reloaded all the firmware and all new sys files...and its still happening.

    I checked the wiring, its all correct, BL touch does its usual pin cycle on powerup. Any help would be greatly appreciated. Here is my current config settings.

  • if you comment out the first 2 lines, does it stop?



  • No. If I manually enter the M208 Commands, it throws the same error



  • @jay_s_uk Sorry.. M280 not M208



  • Disregard. I figured it out. I was testing the Workbee CNC DWC on this machine yesterday before I installed it on the actual CNC machine. It installed RepRap2 on the board. When I put RR3 back on it the issue went away.
