Marlin 2.0 Unified Bed Leveling
# General Process
Pre-heat Bed/Nozzle
G28 Home
Determine Z Probe Offset using paper shim method
- M851 Z 0.0 Reset Z Probe Offset to Zero
- G28 Home Again
- Disable Software End Stops - M211 S0
- Raise bed until paper just scratches the nozzle
- Record that number as z-probe offset
Set Z Probe Offset in Firmware
- M851 Z-2.43
- 2/14 - After tightening hot end heat break to heating core, Z-3.070
Note: I measured with a post-it and read -3.3 when it really pinched the paper -3.25, my final offset was -3.45, this seems to be somewhat typicall to be off by a few 10ths of a mm
G28 Home
G29 P1 Probe Bed
G29 T Print Map
G29 P3 Fill in missing matrix 8
G29 P3 Fill in missing matrix 9
G29 S0 Save Mesh to Slot 0
M500 Save to Firmware
Mesh Notes - Positive Values move print head AWAY from the bed
- A value of -1 puts nozzle closer to the bed than -.5
Update Scritps section in Simplify3d to load the mesh and enable Auto Bed Leveling.
G28 ; home all axes
G29 L 0; Load Mesh 0 from EEPROM
G29 A; Enable ABL Mesh
Print Test Squares to see how the mesh looks.
Questions - Is Z-Probe offset different at different temps, I think it may be!
- When printing higher temps, look to reset z-probe offset?
- My test PLA setting is at -2.40 but my PETG was -2.47
- Test again with higher bed/nozzle temps
## MESH PROBE Warm Bed Scan with Z-Offset of -2.43
