@deckingman This does help me a lot, thank you!

Hi @deckingman

Thank you for your response and willingness to find out.
I am building a 3D printer with multiple extruders to print and mix fluids. In order for it to work, I need to be able to reduce pressure in some lines (retraction) while extruding from others at the same time. Until now, I was only able to this in separate GCode lines, and this Gcode command seems for me the only way to integrate this. But I would like to know if it is possible at all before I start messing around.

So it would be an enormous help if you could let me know if this works

Hi

If I define a tool using M563 like tool 0 with M563 P0 D0:2:3, I can extrude different amounts of filament from different extruders, right?
My question is wether these numbers can be negative for one extruder and positive for another.

So would a command like G1 X90 Y15 E2: -1:10 extrude 2mm from extruder 0, retract 1mm from extruder 2 and extrude 10mm from extruder 3 using tool 0?
