So, I've just finished building my latest CoreXY with yet another Duet 0.8.5, IR sensor and PanelDue with the Flexion Extruder. I'm interested in trying to make this do a manual color change. Is there any G-code that is supported in RepRapFirmware that I could put into my tool change code that would do something similar to the Pause button on a PanelDue?
I'm thinking if the G-code pauses for a tool change, uses M117 to display a message about changing the filament, I manually unload and reload the filament, and then manually resume the print. This would then allow me to "multi color" a print manually. I'm not talking a lot of color changes,but was curious if this was possible in the G-Code?
