XYZ CALIBRATION
The purpose of the XYZ calibration process is to measure the skew of the XYZ axes and to find the
position of the 9 calibration points on the print bed for the proper bed leveling.
MEASURING THE DISTANCE BETWEEN THE TIP OF THE NOZZLE AND THE PROBE
1.
Place a sheet of regular office paper under the nozzle and hold it there during the first round
(first four points being checked) of calibration.
If the nozzle catches on the paper during the process, power off the printer and lower the probe slightly.
Check probe height.
The paper will not affect the calibration process. The nozzle must not touch the print surface or deflect
the bed by any means. If everything went correctly, continue with the calibration process.
2.
Initiating this process performs a series of measurements in three rounds. The progress and
results of each step are displayed on the LCD. In case of errors found, the XYZ calibration is
interrupted and the reason for error is shown to guide in troubleshooting
3.
At the start of the XYZ calibration procedure the printer prompts you with the following
message: Calibrating XY. Move Z carriage up to the end stoppers. Click when done. The printer
then asks you to confirm this step: Are left and right Z carriages all up?
Make sure you really move the Z carriage up to the end stoppers until you hear a rattling sound as the Z
stepper motors skip steps.
The XYZ calibration procedure also prompts you to: Please clean the nozzle for calibration. Click when
done.
