Cura & Dual Extrusion head first try

[Burgerboy]

@Hauke

With retraction, the nozzle dwells for half a second on the print before tool change. This leaves a scar. I think I’ll try Z-hop with retraction next time. Also, perhaps I can influence the tool change locations to be at invisible places.

It seems that this is a “feature” of Cura. You need to add Extruder end gcode to move it off the model. I use the prime tower so I move it to there.

Dual Extruder - Extruder stringing/blobbing when switching

To resolved the issue you need to add Extruder end g-code into your Machine settings in Cura to force it to change extruders over the wipe tower: G0 X {prime_tower_position_x} Y {prime_tower_position_y} Thanks to D1Spartan for sharing his Cura setting.
