3D Chameleon

Can someone help me out with the gcode to have the printer and 3DCh completely retract the filament back to the start position after a print is complete? I don't know if a portion of the gcode from the gcode generator can be used for this function. I don't know prusa well at all so I'm not sure where to put it even if I had the code. End gcode perhaps?

Also retraction settings in general are a never ending battle, lmfao. The 3DC is performing great

I keep having issues with filament randomly getting stuck in the Y adapter. Sometimes it happens when retracting sometimes it happens when it's trying to feed up to the extruder. If I'm around when it happens I can grab the filament and help it along either way and it sometimes it's fine from them on sometimes an hour later it will do the same thing. I have adjusted the POTS to the 1oclock position. I have also loosened the screws on the Y slightly to make the travel path slightly larger. Nothing seems to help. What can I do to give this system enough guts to move the filament like it should without having to constantly babysit. This system is advertised as plug and play not babysitters club.
