I have RAMPS/Mega2650 running for 3D printing. I'd like to run GRBL on a second Mega with RAMPS for CNC. I can compile and load, but nothing runs. I read that GRBL is for Atmega 328. And RAMPS is for the '2650. A new UNO and CNC board is on the way from China...
I tried a GRBL_RAMPS 1.4, but I can't get it to compile. It doesn't seem to set up a library, or have an GRBLupload .
EDIT: I found GRBLforCyclone, and it compiles and runs on the 2650! Laser GRBL talks to it! Still no compile on GRBL_RAMPS 1.4.
