Application Version

5.3

Platform

Windows 11

Printer

Ultimaker S3

Reproduction steps

Start a dual extrusion print with my custom profile of .1mm layer height and 2 print cores AA & BB

Actual results

Slicing engine prints both AA & BB skirt and starts the print core AA prime tower though skips support core BB for prime tower and every other layer subsequent to the slicer generated supports within the model.

Expected results

Both nozzles print their entire .1mm layer on each layer in order AA-BB

The "eraser" next to the model was supposed to "induce" the support nozzle to start the prime tower at the beginning of the print though the support extruder skips every other layer. Remove the "eraser" and you will see that the support core does not start until 5.1mm when the cura generated supports start.

Don't know if this will help for those of you pythons out there trying to code this fix but removing the prime tower and all unnecessary "erasers" induced the print cores to both print for each required layer
