Hello all I am having a problem with my cnc/3 D printer build, I am using a Arduino mega 2560 r3 with a RAMPS 1.4, I am using repetier software, in the manual movement test, I move y axis forward, then when I try move the y axis back, the z axis moves forward? I read some where the firmware for my mega 2560 r3 might be old for my board?
I have disabled all end stops in configuration h,
Where can I find the correct firm ware for this board?
Thank you Melvin
