Hi,
Quite new to RAMPS, but not to arduino. I'm trying to get a small china 2020 CNC machine working
- I have an arduino mega + a ramps 1.4 and 3 a4988 drivers. I have tested each driver 1 by 1 with a simple arduino sketch, they all work fine
- I upload Marlin-1.0.2-2 and try with ramps + repetier-host-1.6.2 and motors make high pitch noise on X, Y nothing (no amps used), Z worked fine > 1/3 working, i must have some step setting problems (set DEFAULT_AXIS_STEPS_PER_UNIT to 2560)
- i connect 1 driver to arduino following the ramps PIN, send some Gcode to X axis and get it to work a F at 25, send same command in repetier and it works fine using the X controls
- put back the ramps board on arduino, put back driver : X axis is not working ?? Does this mean that the ramps board has problems ? since the driver connected directly to arduino works ?
Not sure if making a wrong conclusion here ?
