Have just repaired the printer (filament cooked along with teflon column) and have decided to go to PLA as it seems the K8200 doesn’t have the balls to bring the extruder to 265C in a timely manner. Anyway, loaded the PLA and started a test bunny but the printer is printing 1-2mm above the print bed. I suspect this may be to do with replacing the extruder nozzle and teflon column but problem is, how to fix it. I can’t locate anywhere in the software. Would appreciate any help.
