Ok just looked and there is nothing connected there on mine, have just read the manual as well on Arc Euro's site and it says 5v on the enables actually disables the drives and if you dont want to have that feature just keep connected. So connecting 5V would do no harm but unlikely it will help unless your drives are the opposite.

I am wondering, do you have the dip switches set correctly? If you have the max microstepping set your motors may be moving just that slow you dont see anything. For example if you had the dips et for 51,200 micro steps it would take 10,240,000 pulses to move one rev, if you have Mach set to the default  2000 steps per inch then that would 5120 inches worth of pulses to move one rev of the motor. If you have the default velocity, 120IPM then it would take the motor 42.6666 mins to do a rev, in other words kind of slow ;D

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

The dip switches on the drives determine things like max current , step/dir or CW/CCW and also the microstepping.
Just had a look at your drives specs and they have a max of 1/64th so not likely the problem :( think the guy in the vid said 1/4 stepping was what he recommended so that would be switches M1 On, M2 Off and M3 On

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.

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.

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.
