Introduction
Before starting a print, Element performs a bed levelling check, to ensure that the bed is ready for printing.
A failure in this process could have several causes. These include: an incorrectly positioned Print Bed, a blob on the nozzle, a homing error, or a build plate that is not flat.
-
-
Element users should check that the Print Bed is positioned completely flat on the build plate, and that the edge is not caught on either side, as in the picture.
-
Array users can skip this step.

-
A common cause of bed levelling failures is a blob on the nozzle. This prevents the nozzle from contacting the bed properly during bed levelling.
-
Check the nozzle for any filament build up. Heat the nozzle and clean using a wire brush.
-
If you are consistently seeing blob forms on the nozzle, run through our Densifier Alignment and Troubleshooting guide
-
Check if the nozzle is visibly bent or damaged. If so, you may need to replace the Hot End.

-
Follow our Z Homing Error article to check that the bed moves all the way to the top and contacts the nozzle during Z homing.
-
If the bed contacts either the Transition Container or Densifier, follow the steps in the above article to rectify this. Contact Mosaic Support for further help if needed.

-
Following our XY Homing Error article to check that the Print Head homes correctly.
-
If you see homing errors, inspect gantry alignment and check belt tension, as shown in the above article. Contact Mosaic Support for further help if needed.

-
If bed levelling failures persist after following steps 1-4, navigate to the Terminal tab in Canvas device view.
-
In the Terminal, input G28 and press send, followed by G29 V4. This will generate a 49 point levelling grid, representing the measured height of the bed at each point. The first row 0 represents the front of the bed.
-
The 4 highlighted points should be within +/-0.2mm of each other. If not, please share this data with support@mosaicmfg.com for guidance on next steps.
