So, I contacted bobcad support and asked which post processor to use for grbl and the answer I received was “all of our standard post processors are on our website, you can puchase a support package to have custom posts made for you" not quite the answer I was looking for. I found this thread on here and would like to find out if the post above was good on the shapeoko? I have one on order and I also have a seat of bobcad v25 and a seat of bobart, I would like to know if this post works before I go and crash my new machine!

I worked with Al and made some additions to his GRBL_2 post processor.

This is basically what we added.

This post script, if you didn't read through the entire thread

Sets G21 or G20, if you are using Imperial verse Metric in BobCAD.
Raise the Z access automatically before moving to the first cut.
Then after finishing the tool path, returns to zero.
Finally resets the Shapeoko to MM so you can jog the Universal Controller in MM instead of Inches.

I couldn't upload a .MillPst, so you will need to change the file extension.
