MACH is changing my Z zero on its own after the first m05 code.

Pretty certain Mach will not be doing it, something else, but not Mach, if it were then nobody would be using it and there are thousands of users.


I guess I’m just lost, I don’t know where to look next

Could it possibly be the work offsets? I can’t set them to 0.

It needs a careful, methodical approach, step by step.

I would try disconnecting or turning off Proma, fit two switches - Z-up & Z-down to the points where the proma was connected.

Now, with the plasma turned off and code loaded, try running the code and you should be able to jog the torch up/down manually as it goes.

At the end, after M05, issue G0 Z0.5 in MDI and the torch should be 0.5 above the metal.

Don't worry about WO,they will give you a headache, they are rarely zero and only indicate the difference in position from machine home to where you set XYZ zero.

Concentrate on the odd behaviour ;)

My codes all end with
 
G00 z1
M05 M30

Also what is MDI, sorry

I’ve messed with the setting on the PROMA a little bit, and I have noticed: if I leave the delay timer on proma for a period longer than the duration of the cut itself, the z will work fine. If I lower the delay time, for a period shorter than the duration of the cut (PROMA makes adjustments to Z in Mach) the Z then doesn’t compensate for the distance traveled by the PROMA.

Not what i asked, but ok, when your code has finished running(torch off) enter G0 Z0 into the MDI and press enter

MDI = Manual Data Input - its a line/box where you can type G code directly and it will run as soon as you press enter

That is correct = by setting a long delay you are effectively turning THC OFF

The delay is a Pierce delay - it must be set JUST long enough for the pierce to happen and the torch to start moving, no longer, no shorter.

So, I fitted 2 switches to manually jog Z, it did the same exact thing that the proma was doing, so I adjusted my Z axis motor tuning as maybe it was losing steps? It is working perfect manually, I am going to hook the PROMA back up and try it now.

I believe the Z axis is losing its steps. Or something in this nature. I have my Z axis tuning : velocity is 15 and accel is 1. It is working with the PROMA just kind of weird. Needs fine tuning I think
