Is there a GRBL/arduino shield post-processor?

Hi,

Can any tell me if there is any GRBL/arduino controller post-processor for Path projects?

GRBL looks like a very interesting project. I found a hint in the docs where it says that more information about the GCodes could be found on the linux_cnc homepage. So you may try this post processor.

I use GRBL for my machining and have a post processor for it at home. It it's not much different from the linuxcnc, IIRC the biggest thing is to not emit some of the g-codes, like M2. Given the small differences I never thought it being worth to be included in the distribution.

Anyway, I can post it once I get home.

Hi mlampert,

That would be nice!

Attached, hope it works for you.

I was just looking for that...
I've been using linuxcnc post processor too. I had my first issue, though: canned drill cycles (G81) aren't supported by GRBL, but they're generated by the drill operation. Watch out; it errored out in the middle of my in-air practice cut. It was easy enough to translate to G0/G1 commands by hand.
On quick look, I don't see translation for G81 in the post processor.

What do you use for a g-code loader?

I'm using bCNC and that might filter those out for me which is why I never had a problem with those.

I use bCNC too (on macOS 0.9.9 March 24, 2017).
I haven't looked into enough bCNC settings; may be it has filter/translate capabilities.
