If your Q1 is anything like my previous X-Plus or current X-Max 3, pretty much all of the routines you can run from the touch screen are macros that are defined in your printer.cfg on the machine itself. This is just a text file full of gcode and you can dick with it freely without having to reflash the firmware. The only “fun” part will be figuring out which one of the custom macros it is, since Qidi doesn’t always give them a readable name and they tend to make them random looking numeric strings. I’ll have to take a look at mine when I get home and ensure that the filament load/unload/runout routines are located there, but I’m pretty sure they are.

You can directly edit your printer.cfg through the Mainsail interface within the Qidi Slicer or you can SSH into the machine and get a terminal via which you can mess with things directly (username mks, password makerbase).
