Agreed, and I can set the scale such that +X is up.

I had them this way (and will put them back), the piece I was missing is that I will need to either modify the .axisrc or other such hack to make sure everything coincides with this convention. I thought it was something I had configured wrong. I may just be the .axisrc config and I will look at that tomorrow. BTW, I had a chance to observe the Tormach lathe at the recent CNC Workshop. It is a fairly nice machine and the work Tormach has done on the UI is very very nice.

Ok, I completely lost you on using MSG and named parameters to help in getting the values of G53. Can’t I just read G53 off the preview window (I think that is what is shown in the upper left (Not in front of machine but something like Rad: X.XXXX and Z: X.XXXX). I have been zero’ing G54 from the Machine menu because I think that is how I had screwed up my tool offsets a couple days ago. How would I use MSG and named parameters to get that?
