If i measure directly at pins on the cable from the parallelport I will get 3.3v and 0v. With the BoB connected I do not have 5v one way and 0v the other (at P2/P3)

Already done that and its 3.3V. This BoB shouldnt have a problem with it though.
Note that I had  this setup up and running a while ago.

Thx

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?

Hi,

I have this problem with the connection between PC<->Driver. You can se how I hooked up the drivers and BoB in the attachment.
The drivers and Bob are supposed to be wired like this: http://www.brundin.biz/images/datasheets/CW230Elschema1.pdf and i cant find anything wrong with my wiring.
If I short-circuit the P2 and GND the motor will step and If I short-circuit P15 (eStop) to ground the eStop gets triggered so it seems like I have a connection.

Lets get to the problem..
When I jog, the DRO is counting but the motors wont move. I hope anyone here could help me

(I have checked the active low checkbox.)

Thanks in advance
Niclas
