Squaring process sanity check...

[ken_rychlik]

Your thinking is mostly correct. As long as the long rails are parallel, the part about how far a stop is from the end doesn't matter. If you have to pull to hard to get it there, loosen the corner bolts on the y gantry, pull it to the stops, and tighten.

I'm not that concerned about how far the stop block is from the end - I was referring to using it as a way to square the gantry when the opposite end is pulled against its stop block.

tnx.

Are the corner bolts you're referring to the ones outlined in red on this image? https://i.imgur.com/8WBQTuT.png

Thanks!

Yes, but if it's out a lot, you may need to shim things on that one with the aluminum cross bars. I would try loosen move and tighten first.

Awesome, thank you.

I've been able to adjust it via stop-block tweak so that it's only 0.5mm out of square. Left to right is 2574 and right to left is 2574.5. I suspect breaking out the dial indicator in order to move a stop block 0.25mm is a bit much for a machine that eats wood.
