Change filament command
« on: January 27, 2013, 12:58:05 PM »
Interesting. They have just added a new Marlin firmware command to change filament (e.g. to replenish the current filament or to change to a different color) in the middle of the print.

https://github.com/ErikZalm/Marlin/commit/1d06b10962ced3c29e11cea2c6e6c7872588ad4b

Code: [Select]
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.
