As Gerry says no mention of the enables, I cant find any wiring info on the guys site or any info about the actual model of the drives. I am almost certain you are needing the 5v and 0v to the enable pins but best bet would be to email the guy to make sure or if you have the model numbers of the drives we could probably find the correct leadshine docs.

It says on the drivers.

Keling Technology inc

KL-4030

Heres the manufacturers diagram

http://www.kelinginc.net/KL-4030Wiring.pdf

I appear to have everything wired correctly except the interface on the diagram has four power input connections and mine only has three.

gnd,  5v and ena

I have 5v to the 5v and ground to gnd should I put 5v to the ena

According to the wiring diags he has you do not need the enable connected. Best bet is to email the guy you got them from or Keling himself.

I emailed the guy who made the videos this morning.

Now I have 5v to the en on the breakout board. The motors lock up with a nice thunk, but alas still no movement from them.

Attached pic of the end of the cable as it plugs into the breakout board.

Pins 7, 9 and 11 show 0 or 5v when I move the axis on the keyboard.

is this as it should be.

Ok, you shouldnt get 0 to 5v toggle on these pins when jogging the axis if you have it configured as in the video, the Dir pins in the vid were 3 5 and 7 so jogging the X one way then the other should toggle pin 3 between 5 and 0v. Same goes for Y axis and pin 5 and Z axis and Pin7. Are you measuring directly on the computers port or at the end of the cable? If the cable then check it is a straight through cable, sounds like it may be a crossover.

I had some spare time this morning and did some "troubleshooting"

I think the lpt1 outputs are ok now on 3,5 and 7

And there is output from the breakout board.

pins 3,5 and 7 switch between 0.08 ( probably inaccurate meter) and 6,25.

pins 2, 4 and 6 between 0.08 and .2

The motors are locked up.

I am tempted to run a 5v to the enables on the drivers. Could it do any harm to try ?

Thats exactly what you should see (voltages a bit high on the Dir, but  as you say probably meter) so the BOB is OK, the Port is OK, only really leaves the drives.
Personally I would hook up the 5V but thats me, docs are not great so not sure exactly what they mean, wiring shows theres nothing connected but docs seem to suggest there should be.
Dont think you would do damage but not an expert so cant say for sure.
If you hang on 10 mins I will go look at the coil winder and see what I have there, its got similar drives too yours.

Ok I am standing by.

I guess the weather isn't so good where you are, my son is in Dundee but coming home for Christmas.

I am undecided, It would be nice to have him home but he is probably safer where he is.
