I’m not really sure how to answer that question. I’m still not totally sure what the post processor is. I thought it was grbl. I’ll just tell you exactly how I get from design to machine. I do the Manufacture process in Fusion 360, I have Grbl set as my post and have it run as an .nc program. Then I take it straight from my design computer, to the one hooked up to my cnc machine, where I’m using gSender to run the program. I don’t do anything else in between.

Not sure if I answered your question or not?

Yes

There is a generic grbl post processor.

With that post selected, your post process window looks something like this?

You want to change the setting for “Safe Retracts” to “Clearance Height”.

You can also change line 49 in the current version of the PP from
value: "G28",
to
value: "clearanceHeight",

That way, you won’t have to mess with it again.

I will make sure to start changing that setting when I do this from now on! Thank you so much for your help, again. It is greatly appreciated!
