I’d like to build a small CNC system using grblShield, but on the website is stated that the grblShield doesn’t support the Arduino Megas. Is this a pin problem? Is this solvable by not directly plugging the shield on the Mega / DUE?
Technically, it’s grbl that doesn’t support the MEGAs; grblshield would run fine. I think there are some people porting to the mega – so I’d check out the grbl github and issues.
