I am really going crazy about what is going on, I need your help
- new ramps 1.6 + mega + a4988 (only one motor connected to one driver , nothing else is connected ) = motor not moving, stuttering, buzzing, tried everything, motor coils connection is correct, test code, vref, jumpers, end-stops, changed motors, changing to x,y,z, new cables, same result
so
new ramps 1.4 +new mega + a4988 = same thing as above, ok the driver is the problem then, (motor moves with test code but very badly, seems random movement )
ok time for a new driver installed but hell no!, same result as before.!!
ok I get a new driver again from working printer, install, same result
put it back to the printer I took it from = not working printer, so driver is gone
so what is going on, can the first setup destroyed the driver, then the same driver destroyed the second setup ??
