Just got my Glowforge Pro last week. After being pretty happy with the small cuts I made, (the ruler and plague). I decided to make a frame jig for another project i am working on.
However it turns out that the corners are not square.
You can see the gaps between the square and the baltic birch frame I cut. This was my brace.svg file cut about 9PM eastern yesterday.
The material was flat, the unit is on a flat level surface, the crumb tray is in its divots, there is no debris in the divots, tracks or belts.
I read the forums about turning the machine on and rolling the gantry back and forth and centering the laser head under the camera. I did that about 5 or 6 times. Each time I made a very fine (5%) cut of a square shape on some draft board to see if it changed. That process did seem to work somewhat, but the cuts are still not square. I made another cut of the brace.svg cut today at around 1PM, this time on medium draft board.
You can see the difference when I overlay the first baltic birch cut over the draftboard cut. so the gantry did shift, but not enough.
Not sure what I should do at this point. I have seen some post where people mention that they manually squared the gantry them selves, but don’t really see a way of doing that?
