Hi Les/All
I'm having a wierd problem where when i set Z zero the torch lifts up and the torch is cutting air. It seems to be raising half the thickness of the box section - not wall thickness.
P.S. Using PlasmaRotary Mach3 and it is edited according to my machine and Mach 3
Please help

Rotary plugin torch height
Re: Rotary plugin torch height
I think z zero is supposed to be the center of the tube, not the surface.

Hi
Yes I understand that but when you want to zero the machine you get a torch crash as it tries to plunge to zero. Or am I missing something

Sorry, I'm not sure what else it could be. I haven't used the rotary plugin yet. I'm sure Les will be along shortly to assist.

Hi Les
I think I made a mistake by making my ref 0 for z at the top. Does that make sense?
Should I have the limit/home be at the top of z or the bottom?
So confused as the gcode also has a G28.1 in there is this correct?
Sorry to sound so dumb. I haven't had any problems with sheetcam on my 8x4 plasma. Just sayin

Re: Rotary plugin torch height
Yes, for rotary cutting, Z0 is the center line of the tube. If you have a touch-off switch and the post is configured correctly (see below) this should be automatic.
There are two ways you can set up your machine:Should I have the limit/home be at the top of z or the bottom?
- touch-off uses home input. This has the advantage of using one less input but you can't use soft limits. In your post set refHome=true. Thsi will touch off using G31.
- Home switch at the top of travel and touch-off uses the probe input. In your post set refHome=false. This will touch off using G38.1
