Dual Extruder Printer, Extruder 1 sometimes does not move out of the way, go home, when switching to extruder 2.

I am using the JGMaker Artist-D Dual Extruder Printer. Sometimes When using Extruder 2 for supports, extruder 1 stays where it stopped printer and does not move to home, or at least out of the way, causing Extruder 2 to hit it. Does not do it on all prints. I'm assuming there is a setting that I changed by accident but I can seem to find the setting that is causing this issue.

Did you figure this out?  Not many folks who come in here have IDEX printers and my only experience with them is with "virtual" printers I've added to Cura just to play with.  One problem is that Cura does not directly support IDEX printers but they can be made to work.  You are going to have to experiment.  The JGMaker site does have some Cura profiles you can download.

 

Have you tried adding some "ending gcode" to the extruders?  A line like "G1 X{machine_width}" would send the print head to the max width of the bed while "G1 X0" would send it to the "0" side of the bed.

 

The suggested slicer is Ideamaker.  In Ideamaker - The Raise3D IDEX printers get "M605 S1" for Mirror, "M605 S2" for Duplicate, and no M605 line for normal, added to a gcode file.  Cura doesn't do that and so 3 separate instances of your printer would need to be installed each with slightly different StartUp Gcode (the proper M605 lines).

 

Maybe there is a JGMaker support group or a group on Reddit you can ask advice from.  This must have come up before.
