My conduit is 23.4-23.45 and is round. I can’t see any bends putting a straight edge against it, but I can’t be sure it’s not slightly bent somewhere.
I loosened the middle joiner bolts a little, but not all the way as I don’t think I can get those bolts out without disassembling the whole middle. I have my machine in an enclosure, and removing the gantry is going to require taking the whole machine out (and unscrewing and re-squaring the frame) so I’m trying to leave that until the last option.
I’m hoping getting the steppers to stay engaged so I can set the start position resolves most of my issues. Is it normal for the gantry to be a little out of square when relaxed, or is still a symptom of something else wrong?
