I've been dealing with a centring issue. Every time I try to engrave a piece (same pieces, same artwork, same files, same software, same computer), The engraving seats a little bit to the right, or a little bit to the left (1mm or less in average) in random events.
I already replaced the Laser head holding unit for a new one, I've also checked the belts tension, and several other trials, like: sending the file with / without homing first....etc...
It seems that something is moving from its place, between the engraving sessions.
Has anyone ever had this kind of issue before?
I'm kind ofdesperate, because my clients are waiting for the products I produce with the emblaser, and I've lost many pieces until now.. So I would appreciate a quick help on this!
