I have a 1 month old Aritsan with the 40w laser module. Recently the crosshairs have rotated, they are no longer square with the fins on the bed, this is a new problem as of yesterday 9/25. They have been previously been square with the bed during alignment of workpiece, they have now moved significantly. Any help would be appreciated.
For troubleshooting the first thing was clean lens, test different files to eliminate a gcode issue, reset the machine and reinstall firmware, remove the module and check for loose hardware, recalibrate platform, check dimensions of rails to ensure they are square, dissemble module to see if alignment lens was loose.
My assumption would be that the crosshair projector (red laser plus lens system) got dislodged. Since the module is under warranty still, I’d refrain from trying to fix it yourself, but contact Snapmaker for repair or replacement. If it is out of warranty, you can open the module, find out what exactly broke and try to fix it. I never looked how the projector is fixed, so I cannot give specific guidance.
