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.
Huh, that’s cheap… Of course it will hurt the function of the device if the crosshairs is not a reliable tool to select the work origin… You will have a difficult time to get reliable laser positions…
That said, If you don’t mind a bit of tinkering, why not unscrew the bottom plate and investigate? Still, with your unit within warranty as I understand, you might insist with Snapmaker that they should take care.
I’ve already tried, the lens for the projector is secure. I can’t find anything loose inside the housing nor anything that could have dislodged the internal components of the laser. Given everything being tight I would assume the projector inside the sealed laser module could have rotated.
Honestly, if I was in your shoes, I’d insist on a replacement of the unit. If it was OK in the beginning and changed without reason, that indicates some problem. While in warranty, I’d claim repair or exchange.
I have already read and followed this (not meant sarcastically). There was no improvement, I haven’t noticed any movement in the cross while jarring but I haven’t tested it. I can test that when I get home from work and reply with results, at this point I will probably request a replacement. Snapmaker has already had to replace the control screen due to random resets during operation.
