aye Hood How you going? I have voltages but they're all over the place. step pin on x is 4.3v direction pin @ 0.9v dont quite know how to jog in plasma yet but have ran a file i created on g code and voltages are constant on x but vary on y and z might look at chnging pin addresses

I would imagine you just use left/right Up/Down arrow keys for jogging X and Y and Pg Up/Pg Dn for Z.
 The voltages  could be right if they are constantly changing if it is the Step pins as they will be pulses so a voltmeter will only read the average and how much that is will depend on the speed of the jog/motion. The Dir pins however should either be 5v or 0v, your 4.3V is close enough to 5 :0

Its best to start at the port with the cable disconnected then if that checks out put the cable in to the port and again check at the other end, that way you know what is coming out the port and then getting to the breakout, testing while running at the breakout output will just tell you if there is a problem somewhere but you wont know where.

Hi Hood, Have check continuity of the cable and all is good. am going through the motions of testing the signals but not being able to jog makes it a bit hard. How do I get the jog working to test out the motion?

EUREKA I have movment. Well y and z movements. Have found out how to jog and it seems that I now have a problem with the port on the mother board. Step gives me 4.3 volts and dir 0.09 and changes to 0.091 when a direction is enteredwith the jog. Has any one come accross this before?

I Have now movement on all axis although they do not correspond to the board. Axis X is axis Z on the board, Axis z is axis A on the board and Y is Y on the board. Cannot seem to get x to work of the board. I have changed the pin addresses on the Motor output and nothing seems to get me there.  The Problem was not the mother board but the wrong pins. Has any one had this trouble?

Hi Guys Thanks for your help it is much appreciated. Still have not resolved the issue of the wrong axis configuration but will persist. Am Happy for the moment to see things rotating almost as they should. Still have a bit more fine tuning with the motors. It is great to know that there is a support base like this. I hope I can contribute to others once I have learnt a bit more about the wholle CNC bizzo.

Hi,

Don't know if you've solved the problem yet, but I had the same problem and discovered I had not wired up the enable pin to 5v when I initially set up my break out board.

I hope this helps.
