Thanks for the effort on fixing this.
Why is the G8* translation not the default. GRBL does NOT support these GCODEs . Did I mis-understand?
Does git-hub master build correctly now ? Yesterday it failed when opening Path work bench.
I just deleted my local copy of PathScripts/Post and got a clear copy with:
git reset --hard origin/master
I still seem to get the old versions with grbl_G81_post having execute permissions for all.
EDIT. OK, not sure what was going on with versions. I deleted the tree, got fresh copy and only see the new grbl file. However xxx permissions, is that intentional?
