Thanks! Can you also update the END GCODES? I think something's off. I got a RTP V4 and whenever i use Cura, I get a large retraction when the print ends. It retracts to the point where it separates from the hot end. So i have to manually feed it back close enough where i can run the Load Filament Macros again.
Or i can just copy and paste the Cura Single Extrusion Guide end gcode.
The line you identified is there to back the filament out of the Y splitter on dual-extrusion machines. You can comment it out by sticking a ";" in front of it.
