You can see the home/autolevel/priming sequence starting at 06:30. I'm using Roxy's enhanced G29 code.

Here's the startup sequence:

  • Heat the bed
  • Start heating the nozzles
  • Home and probe for autolevel (G28/G29)
  • Park at Z=0 with both nozzles off the glass
  • Wait for both nozzles to reach temperature
  • Prime the left nozzle wipe it onto the glass
  • Prime the right, retract it slightly and wipe it onto the glass
  • Print alternating loops (Slic3r)
  • Print


Slic3r prints the outside ring with the left nozzle first; that's why I retract the right nozzle slightly. This keeps it from dribbling while the left nozzle prints loops. After that, Slic3r automatically handles the retracts.
