I have a Ender 3 Pro with Micro swiss all metal hotend, Bltouch and a 4.2.7 motherboard. I encountered a problem I cant seem to figure out, my extruder works fine when I manually tell it to purge, it also lays down the purge line at the left side of the print bed at the start of the print but when it starts to print the actual print the extruder just stops moving. When I reinstalled Cura it worked fine for a couple of prints but then the same problem again(this really confused me). I have tried flashing the firmware with no luck. Any help to solve this would be much appreciated.
