Discussion of new M600 Change Filament command

Recommended Posts

This is a continuance of a discussion regarding the M600 Change Filament command which was recently added to the Marlin firmware. I have move the discussion here so that it has wider visibility.

Details of change:

https://github.com/ErikZalm/Marlin/comm ... 872588ad4b

 

 

Added a feature to have filament change by gcode or display trigger.

[default off for now]

syntax: M600 X[pos] Y[pos] Z[relative lift] E[initial retract] L[later retract distance for removal]

if enabled, after a M600, the printer will retract by E, lift by Z, move to XY, retract even more filament.

Oh, and it will display "remove filament" and beep like crazy.

You are then supposed to insert a new filament (other color, e.g.) and click the display to continue.

After having the nozzle cleaned manually, aided by the disabled e-steppers.

After clicking, the printer will then go back the whole shebang, and continue printing with a fancy new color.
