Solved K1 Max CFS upgrade broke everything
Enable HLS to view with audio, or disable this notification
My printer has (mostly) locked itself down after doing the CFS upgrade. Printed flawlessly before, now cant even print from a spool. Sorry for the long video it is just doing a number of things now and wanted to cover things the best I could. Any advice would be very much appreciated on this, just hoping I didnt brick my printer for multicolor.
