A-Star for CNC?


Is there any software similar to Grbl that could be used in the A-Star?
Hopefully one that can use the SD card to load GCODE files and the LCD for simple display?
Could it use the Arduino shields available for stepper motor drivers?



I do not have any specific recommendation for software that has all those features. The A-Star uses the ATmega32U4 microcontroller, which is the same microcontroller as the Arduino Leonardo, so if you can run it on the Leonardo, you can probably run it on the A-Star.
