I think I found the problem. See photo below. The 4 screws that hold the laser mounting bracket to the X-axis slide plate were loose allowing the whole laser head to wobble left and right a few mm. They are also stripped so I can’t really tighten them. Off to the hardware store to try and match these tiny screws.
Very disappointing since this connection was made at the factory and came preassembled. I only had to mount the laser head to the bracket.
I will keep you posted on if this solves the problem once I can find some replacement screws.
