I’ve got 3 K2 plus machines, all with 0.8mm nozzles. 2 machines have been running for 1 month, 1 machine new yesterday. Mostly trouble free (2x jams in extruder 1x jam from broken filament in CFS). I’ve been running quality white PETG, using the Creality Hyper PETG presets the whole time, and have put about 15 kg of same material through first 2 machines (yes, I’m printing a lot of large (0.4kg) prints. Same file printed perfectly yesterday in new machine and 1 of the older machines. Then it seems like there was a firmware update, and for the first time I got a notification that the RFID in the CFS couldn’t identify the spool. I went in and manually selected it, other two printers didn’t report RFID problem.
