Its not printing correctly

I was making dovetail boxes and they are not coming out right. The pattern is correct but when it prints they are off just a little that the boxes will not go together. I checked the alignment and it was off a little so I calibrated the machine. I then ran an alignment check again it was right on.

I printed this. The pattern is perfectly lined up. The 3 layers should be the same but they are all slightly off. The word should be centered. On 2 of them (the ones on the right & left.) the circle did not meet up. I had to cut the wood by hand to get it off the background.

HELP. I have never had this problem before. I have several orders that are time sensitive that need to be made.

Circles not meeting up correctly are an indication of a cracked wheel or incorrect belt tension.


Would this be a wheel on the part that carries the laser head and the belt that moves the head?

Start and end of cuts not lining up can also be caused by the laser arm being crooked. There’s a guide for fixing that as well:
