I dont think the BoB requires a enable signal. I have the "KL-DB25 Breakout board" from kelinginc.
The dip-switches shouldnt matter though I cant get a pure signal (+5V / +0V at P3, dir-pin), correct me if Im wrong.
With no output signals from mach the voltage over P3 is like 5.13V and when I change jogging-direction in mach3 the voltage lowers to about 4.87V.
Makes no sence, shouldnt it be near 0V?
