I tried to run that sheldon without jog dials or cranks, and while it could be done given a real mouse and keyboard, the intermittency of event detections from either input led to some interesting tool crashes and pricy cutting chip destructions. I probably more than doubled the size of the hal file by adding those MPJones dials, 2 of them, along with a range switch/enable button per dial, right on the replacement apron panel. The pushbutton switches the logic so it sets the size of the per click incremental move when its pushed, starts a activity timer when its released, retriggerable by moving that axis with the dial until the dial hasn't moved in 5 seconds.
The motions achieved are as accurate as the axis scale setting. The biggest squawk I can lodge is that the pushbuttons I used need at least a 15 lb push, then another 5 to actually close the switch. I've found some that are much easier to push, but have misslaid my round tuit. It will get done when I next need to pull that apron plate off again.
