The manual for the PCNC 1100 says that it needs 84 inches clearance height wise. I assume that is to the top of the Z axis stepper. I would like to install the mill on the same side of my garage as my lathe, but the garage door and track is exactly 84 inches from the floor, but it is somewhat away from the wall. How high exactly is the Z stepper and how far is is the front of the Z stepper from the wall, if the mill was as close to the wall as possible?
