Dual Extrusion - nozzle switch retraction problem

Recommended Posts

Hey! I'm new here.


I have a problem. I am using Cura 3.4.1 to use dual extrusion for my Creality CR-X, and I'm having trouble getting it to work. It has a single nozzle, and two extruders, so I need to retract one filament and make the other return to normal position. I put the Nozzle Switch Retraction distance to 90mm, and sure enough it retracts 90 mm when changing extruder, however it does not return the filament on the other side to the nozzle, and so it prints in mid-air until 90 mm later, where the filament returns. Is there a setting to make it return the filament? It worked in the bundled old version of cura (15.04.6) which came on the SD card, but there is no specific setting in there. It's just a "dual extrusion switch amount".

Thanks!
