My torch seems to slowly get closer to my sheet of steel at the end of my gantry. I have leveled, measured and tightened the bolts several times. I can use the larger spacer and as the gantry returns and the gap almost tripled. When the gap stays consistent it only stays that way for a few projects then the torch starts touching the metal again.
Water table and slats are level.
Gantry arm level
Clamped metal down
It’s just frustrating to get a couple cuts then have to adjust everything again.
I’m a mechanic by trade and I’m not a complete idiot.
