Increase initial purge volume
How can I increase the purge volume at the beginning of a print job? I have parts that end with dark colors and others that begin with white. The dark colors need additional purging when starting a new print with light colors. The purge tools for the mmu are only useful for the purge tower, not for the initial purge at the start. I've tried "purge all extruders" but there's a bug that causes the gcode to hang. I've also tried adding a modifier but can't figure out how toget it to print first. Any ideas?
RE: Increase initial purge volume
Easiest way to do this is to add a few lines skirt. Or you modify the start gcode to do a third pass on the edge of the bed before starting.
If at first you don't succeed, skydiving is not for you.

RE:
Add additional G-code commands at the beginning of your print job. You can include commands to extrude more filament before starting the actual print. For example:
G92 E0 ; Reset extruder positionG1 E10 F100 ; Extrude 10 mm of filament at a speed of 100 mm/minG92 E0 ; Reset extruder position again
If your slicer allows, create a custom modifier that includes the purge action. Make sure to set it to print before the main model. This might involve adjusting the modifier settings to ensure it executes first.
