Small error with the PlasmaRotary Mach3 Post

Hi,

There appears to be a small error with the PlasmaRotary Mach3 Post. I haven’t quite figured out how to fix it. Here is the file… The problem in red.

That is being inserted before every G28.1 and I believe it should only be inserted when there is no G28.1 (reference) The z rapid is down to pierce height.


I believe this is showing up because of the OnRapid. I’m thinking that there should be an “if” statement in that part of the post… Something like if reference distance. is less than xxx … it should either output the z rapid down to the pierce height or do a g28.1 and no z rapid before the g28.1


I hope I explained that well enough!

Could you give me a copy of the job file so I can run it hare and see what is going on. Is this on the stable version or the development version?

This is developmental ver 6.1.38 But it also does it in the stable release. It is definitely in the post processor and not sheetcam itself. It should ignore the pierce height move G0z.15 if it is doing a G28.1 Reference. But do the G0z.15 if it is not doing a G28.1 Reference… I tried a few changes in a test post but I’m definitely not a coder! :slight_smile:

Here is the Job file.

Thanks!

Hi Les,

Have you had a chance to. Look at the post?

Thanks!

If this helps any, one thing I noticed is when I do a Drill Pierce it works correctly (doesn’t have the extra Z move before the G28.1)

Oops, sorry about that. Give this version of the post a try.

That’s looks like it works perfect!! Thanks!!!
