Setting up soft limits in UCCNC .. "Logic"

[Kitwn]

Regards Backing off the HOME switch then the only point to me, other than to relocate MACHINE ZERO position is to stop potential false trips if using same switch has limits combined with homing or to square a dual motor gantry.

A precise and detailed description of my own machine!

I love threads like this, I always learn a great deal myself and as I discovered when I took up teaching technical stuff to adults back in the 80s, there's nothing will show up the holes in your own knowledge more effectively (brutally at times!) than trying to explain things to someone else. I now need to swot up on the full details of G54, G55 and other relevant codes and exactly how LinuxCNC uses and saves them.

The difference between machine coordinates and work coordinates is, as Neale pointed out, a confusing one tro begin with but soon becomes one of those fundamental bits of knowledge you don't realise you never knew.
