Hi, My system frequently resets the z cutting height midway through executing a file. It doesn't happen all the time. Can anyone shed light on this ?
Cheers

Do you have an external  button that will set the Zheight?

just the ones within mach3.

Have had similar experience - but it always appears to be the result of something I have screwed up.  Generally this has occurred when when producing G-code in LCAM and I failed to notice a "Z" height or depth change.  Now, I make it a practice to edit the G-code and look for changes in the "Z", parameters.

OK good suggestion.At least it will stop it happening.Thanks

Found the problem which was interference from cad program minimised in tray bar.

Is this a closed case? Will you confirm that it is fine now and the error was caused by

interference from cad program minimised in tray bar.

?


Just trying to keep up.

Yes Problem solved. It was definitely some call the minimised cad programme was making.
