Z-Offset did not calibrate properly
Step 1 - Confirm the problem
It is easy to check if something has gone wrong while calibrating the Z-Offset by using the GCODE terminal in the BuildBee maintenance console.
- Access the GCODE terminal, access your list of printers at the top of the BuildBee interface.
- Select the 'MAINTENANCE' button next to the printer you wish to use GCODE commands on.
- In the Maintenance console, select the 'MAINTENANCE' tab to reveal the GCODE terminal.
- Type M851 into the GCODE terminal and press enter. You will see a message like this:
The default for the 'Probe Z Offset' number is 10. If the value that was returned from the M851 command deviates too much from the average (e.g. it returns 0 or 15 etc.), something may have gone wrong during the calibration process.
Step 2 - Reset the Z-Offset
- While still in the GCODE terminal, type M851 Z10 and press enter. This will tell the printer that the Z-Offset is now 10.
- To permanently store the new Z-Offset value, type M500 and press enter. You will see a message similar to the one below that tells you the setting was stored:
- To confirm that it’s all worked, type M501 and hit enter. This will load all of the printers settings in the GCODE terminal; at the bottom of the response, you should see the new M851 value (Z-Offset).
- Alternatively, you may upload this GCODE file to BuildBee in the 'CONTROL' section of the maintenance console and let it run.
NOTE: Since this only returns the Z-Offset to a default value, you will still have to run a Z-Offset calibration to fine-tune your printer's performance. You can find the article on how to do that here.
