Thanks all!! I guess I'm set then!!
Prism ... we did level the frame but we used the machine to tell us if it was out of level. If the machine migrated by itself, we adjusted accordingly. We kept adjusting sides and center until the machine stayed put both side to side and front to back. Now if I move in any direction and let go ... it stay's put. Oh ... feet ... my machine has 4 rubber feet on the bottom of the machine case.
The last thing we need to work out is the electrical. The wall outlet is high on the wall and the length of the cord for the SLR isn't long enough so we needed to add an extension. But the capacitor for the SLR is heavy and wants to drag. I've also managed to snag the SLR cord under the carriage frame while moving the machine. So we need to rig something up where the power cords are coming off the back of the machine up and away from the carriage. We'll get it sorted out.
