Out of square gantry

Out of square gantry

Postby glassart » Mon Oct 23, 2017 8:03 pm

Hi
I am a new member, bought a black toe kit a few years ago and built a 2' x 8' machine.
I have been busy with work and played around with it on and off.
Finally getting serious with it and have been trying to dial in the machine. My problem is the gantry Y axis is out of square with my table rails X axis. What I have tried so far is adjusting my chain tension to compensate while this works short term is reeks havoc on my motor and shaft couplings for the X axis, to much tension to hold it square, and I read on this forum that it is not good to have the tension to strong.
Plus I would think that equal tension would be better for my machine anyway.Any ideas on how I might square the up, The gantry tracks well on the rails just not sq to them about a 1/4" out.
Thanks Bill

There are a few posts on here, including one I wrote, about the process of squaring the gantry. Try the search function.
If you don’t have time to do it right, when will you have time to do it over?
