Now I've finally got my table running, no plasma yet, just setting up, I am trying to figure out soft limits in mach as it's a bit to easy to jog into the limit switches.
I have an envelope of 650x650mm so I set my minimums to 0 & 0 and my maximums to 650 with a 10mm slow zone but it didn't seem to work, have I set the soft limits correctly??
Also, when I tried to re-run a previously working test code, I get a G54 error.
This is all new to me so I thought it best to ask.
Also, on a plasma table, is Z0 torch up or torch down?
My preference is for Z0 to be with the tip touching the machine table.

Make sure you have auto zero chosen. Also have you enabled the softlimits via the button?

Auto zero does work when I do a home-all, will double check in the morning,

If you still cant get it working attach your xml and I will see if I can find a problem.

Got it sussed now, the biggest problem was that the slow-zone was way too small, bumping it up to 50mm got it all working nicely.
The z-axis threw me a bit off course as it's all negative number but once I figured out what was happening it all clicked.
