Hi All, i'm building a cnc router using arduino with cnc shield build almost complete, starting to use openbuild control but coming up with 2 types of errors most likely user error as i'm new to this if somebody could explain what the 2 errors are and how to fix, but need to understand them 1) error:NaN - undefined [$j=G90G21X0.000 Y0.000 F5000] 2) ALARM NaN - underfined [G0 Z5]
Probably not Grbl 1.1f on that arduino. Upgrading to 1.1 will not match the pinout on the chinese clone shield.
