I am having a serious problem with my Gen 3 electronics.
All my steppers will only drive forwards when jogged in the RepRap host.
When I reverse the direction and jog a stepper driver backwards (any number above zero), nothing happens.
I have tested the Dir pin, and it is being held low to indicate backwards movement, and high when driven forwards.
I have also used simple G-Code that just drives only the steppers forwards and backwards, the effect is that they are only going forwards, no backwards movement
I have also tried updating the firmware, same thing happens.
I'm using RepRap host 20090804 with Java 1.5.21
I have absolutely no clue why this is happening, and I could use some help please figuring this out.
