Bill, I do not see an option in the MK3 gcode generator for Cura as a slicer. What do I need to change to my current tool changes codes for the MK2 Cura code to enable the MK3 upgrade?

What is the gcode or mcode for calling the active tool number? I want to cycle the filament at the end of the print to form then end and retract just like it does for the tool change.

Hello Bill, Thank you for responding to my other questions this weekend. After some tweaking to the code from the GCode Generator and running filament back in forth in the PTFE tubes to loosen them up a bit, I have successfully loaded the filament into the extruder. However, when trying to retract the filament after the tip is formed, the diameter of the tip is now too large to pull back through the PTFE tubes. I increased the extruder temperature to 220 hoping that might help but no luck, still can't pull it back. Any help would be greatly appreciated.
