Change filament change speed
Hi,
My Mk3 printers are running geared extruders with a bowden setup, currently the filament change that is triggered by the runout sensor takes forever because I cannot find how to adjust the speed that it unloads filament at while it performs this procedure. The distances are all correct and it loads at a decent speed but I need it to unload about 10x faster. I have multiple of these machines that need a filament change about once a day and waiting 60 seconds for it to unload each time is a gigantic pain.
here are my filament change settings in the configuration_prusa.h, if anyone could let me know which value to change to increase this speed I would be very grateful.
