So then....PLEASE don't leave us hanging. lol
What was the guilty culprit ?
Glad you got it going !
RC

That's the point I didn't do anything I hadn't tried before. When it finally worked the motor outputs were set low active although I had tried that before and it didn't work. And I have since changed the x & y axis to not low active to get them to travel in the corresponding direction to the keyboard buttons.

I would be happier if I knew what was the problem but its great to have it moving.

She's running

Thanks to John at kelinginc.net

He sent me excellent instructions on Mach3 I just went through all the steps and redid everything.

Kind of startled me when the motors turned.

Thanks to Hood and the rest of you guys for your input.

That's me sorted till the next prob crops up.

I have been all over it again for the umpteenth time

24v to each driver

5v to each driver

step & dir to each driver

4 wires from each driver to each motor

out put v from breakout board to drivers

I guess the only thing is to get another driver to test with.

I guess you are going to have to tell me about dip switches if you don't mind.

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.

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 ?

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.

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.

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.

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
