3D Printed Overlay for DM42, DM41X ...

[EugeneNine]

It depends on how thick the print is, i.e. how many layers. If you go more than a couple layers between switching colors then the nozzle will drag on the outer layer.

Ideally you print layer 1 color 1, layer 1 color 2. Then layer 2 color 1 layer 2 color 2, then layer 3 color 1, layer 3 color 2. etc.

I want to replace the mainboard of mu printer with a dual extruder for dual colors.
