NEJE 4 Max
GBRL controller
System firmware v2.2.3
NEJE firmware v2.2.5
GRBL firmware v2.2.4
LightBurn version 1.7.08
Connected to Microsoft Surface running Windows11 via USB
Issue:
Setting up new Neje 4 Max to use camera for detecting material not working. LightBurn Camera Alignment Wizard doesn’t adjust the Z Axis when modifying material thickness, resulting in Laser nozzle not focusing correctly and crashing on top surface of material (6mm corrugated cardboard).
Troubleshooting steps attempted:
- Updated firmware
- Verified Z height works for setting material thickness in Cuts / Layers
- Verified speed and power settings work normally in Cuts / Layers
- Tested multiple Material Thickness variables (6mm, 10mm, 15mm). All result in laser starting from the same Z height and hitting the surface of the material (only when using camera alignment wizard).
- Cuts / Layers pane shows the speed, power and thickness for the Fill and Line cut list, but these also don’t update to reflect the modified speed, power, thickness values in the alignment wizard (visible but not editable in the background behind alignment wizard pop up window, which leads me to believe there is something wrong with the alignment wizard…)
Other variables: I’m using a custom GCode (G10 L2 P1 Z-43) to auto home the laser Z Axis height to accommodate for the honeycomb bed and 23mm focus height. This should allow LightBurn to adjust the material thickness for each cut layer. This adjustable height works for normal cuts, but not within the cameral alignment wizard.
Any help would be appreciated
