I recently updated firmware on my k2 plus and it’s failed every print since. Before update it was perfect. I tried to reinstall previous firmware. But it does not boot it up on start up. It’s in the right format and on a small 7gb usb stick. Just doesn’t seem to want to let me return to a usable printer.
It will print a few layers then stops the print and says its not extruding. I went back to just using the reel on the side of the machine but it made no difference.
I went from perfect prints to a completely terrible printer that is not usable at all and the only difference was the latest firmware update, that i can’t seem to roll back
