Setting up soft limits in UCCNC .. "Logic"

[John11668]

I think I am getting it Neale and I must admit I had never considered the Gantry machines.
I did work with NC gantry routers in the aircraft industry in early 70s milling Jaguar wing skins complete with pockets, ribs and stringers. A 70mm slab roughly the size and shape of the wing, was held on the table by Vacuum while most of it was machined away. One man "operated" the machine . Or really he watched it .
Three others removed barrowloads of swarf to the skip in the yard and they really did have to work.

In those days the machines were tape driven and " wizards" came in from elsewhere to set the machines up. CNC was spoken of in hushed voices as a black art.

Quite a few topics have been covered in this thread above , which really have served to reduce the mystery a tad, so now I can go and play a bit and make sure I have grasped the principles .

Thanks to all !
