Sorry, I'm new to 3d programming. I can track your cartesian coordinates, but then you call for a filament pause. I don't know what's included in that command but it looks as if something is missing.



  • M600 - Park head to allow filament change or pause of print
  • M601 - Unpark head to resume printing
  • M602 - Turn on/off current extruder motor (e.g., for cleaning)
  • M603 - Display LCD alert, sound beeper and wait for button press.


I'd think a M601 would be necessary to resume after pause. But you've said that your process has worked in the past???
