x stepper keeps going up
Hi
i am in the process of building first printer, a rostock with custom dimensions. using arduino mega 2560 + ramps 1.4.
after configuring config.h on the website. managed to home and manually move the carriages with no problem. on my first test print, it starts fine but x stepper keeps going up, every time a little more, if i stop print and home it all goes back to normal, till i start printing again..
any ideas?

I found that the pololu x drive was set at 5 amps and the rest to 1.4 amps. So I adjusted variable resistor to 0.9 amp in passive state to all of the driver's which when homing deliver 1.6 amps and printer working like a charm!
