Your experience seems to contradict Lee's in regards to the limit behavior. So once again the questions comes: Which is right? Does the gantry move until both sides hit the switches, with the slave moving forward to compensate or not? Very confusing info out there on this one!
Couple other items to work through:
1) Not entirely sure my gantry is cutting the same height all the way across. Placing a level across the table, the table is level. Placing a level across the gantry the gantry is also level. However I notice it is cutting deeper towards the Y+ side then Y- side. How much I haven't measured yet. I also hadn't surfaced the spoil board yet, but a quick look seems as though it would be taking way too much off of one side to level it.
2) Hopefully a software setting: cutting a 18" square yields a 17 1/2" cut. Cutting a 6" square yielded a 5 1/2" cut. Will post in VCarve forum, but with a 1/4" bit selected and a 'outside' cut selected in the software I would expect the software to compensate for the bit size. Seriously doubt a step losses, especially with Nema 34's and 1/4" cut depth in two passes - its doesn't sound as though there is any strain on the machine at all.
