Did you copy/paste or type it?

seems ok to me

SheetCam is a good app.

My setup has a pneumatic actuated probing switch, custom probing macro, screenset, external THC and various other bits and bobs.

I’ve never heard of a setup like that. Sounds complex! How does it work?

The probe switch is mounted on a small air cylinder, your one will use the nose of the torch to sense the material, my one uses a very delicate switch, in the macro the head is moved sideways a little to place the switch where the pierce will be, the switch lowers, the head then drops until the switch triggers, the Z position is set, the switch lifts up, the head lifts up, the head moves back to pierce position and away we go.

It sounds complex but its not and its pretty fast, the big benefit is that i can sense very thin material without the weight of the head/torch deflecting it downwards, IIRC I was the originator of the air cylinder probe and I'm glad to say others have used it as well now

Here's a video, it was early days then but functioning.

I tried using the MP1000THC PP and it seems the torch is jogging up to find the probe instead of down

I think there is a setting for that somewhere

Great, thats a step further.

Now you need to modify your code/post processor to add a probing routine before each pierce, sorry but i cant help here as my setup is mega-modified and won't be applicable to yours.

Someone will be along though

I deleted the file, made a new one with a couple of returns after the code.

Not had the issue again yet.

1st thing is to get the switch to show up in diagnostic screen on "probe" or "digitise" input.



Edit

beat me to it

Its always best when setting distances and checking them to use as much travel as you can measure accurately - it reduces errors/increases accuracy.

so you set the x and not the y?

you need to repeat the adjustment for the y axis, that should help

when you go to auto setting there are buttons for each axis - choose y and try that

once you get them working you need to repeat the settings with as much travel as possible - 14mm is far too short for accuracy

Yes LIMIT is a physical switch at the end of each axis travel, its optional, you could fit it as just a HOME switch or let mach3 use the limit as a combined home and limit switch.

I would install as a home switch as you only need one switch per axis and then setup soft limits.

If using limit switches you need one at the end of each axis.
