I have S3D's FlashForge Creator Pro 2 profile loaded, and I'm attempting to make a two-color print of a 20x20x10 calibration cube. I created two processes, one set for 'right extruder only' and 'stop printing at 3mm' The other is set for 'left extruder only' and 'start printing at 3mm'. When I selected 'Prepare to print' and selected both processes, I got two 'The selected process is not configured for the number of extruders you have chosen to use' warnings. I selected 'Continue' to both, and the resulting print preview looks correct, as shown in the screenshot below.
However, the actual print failed. The bottom portion (right extruder only) printed fine, but at the 3mm transition point, the right extruder wasn't retracted, so the left extruder crashed into it, and the print failed. I suspect the tool change gcode maybe still assumes the two extruders are on a common module and aren't independent like the FFCP2?
I have also attached the .g file and the FFF file for this print.
