Is the grbl code on github directly compatible with the grblShield, or does it need to be patched? I see references to patches on the grblShield github, but it doesn’t appear that it has been updated for a while.
The grblShield is compatible with the current grbl releases from 0.7 onward with no patches. We work closely with the grbl project to ensure this is true. Thansk for pointing this out.
