Artemis 300 - Not able to calibrate zero or bed level

Post by Quint »

I recently changed a cooling fan and nozzle on my printer and after starting it back up, I attempted to map the bed for a test print.
But, while leveling, the settings appeared to be way off. I still ran a test print and while the center appeared correct, but the print head rose progressively higher the more it travels from the center. I checked the glass bed and it is dead level across its circumference.

I checked the home position and found that the head position was off. Belt tension has been checked and the config-override.g/heightmap.csv files were deleted and created with a new 'first probe'. This wasn't successful either.

Any help would be appreciated in correcting this issue. Below are the current settings.
Thank you

This is your clue: "Warning: Z probe readings not consistent". Is the nozzle perfectly clean? Does the bed glass move at all?
Also make sure that the bed heat is off during calibration - the magnetic field created by the bed heater will interfere with the strain gauge circuit in the hot end assembly. (the bed can be heated up, but the bed heater must be turned off for z probing)
