Motors wont turn

[moto21]

Im going nuts here. I have 3 G201's, automationdirects 434 steppers, a 24vdc 6.5 power supply, winford brakout board, and running mach3 mill. I did have these motors turning fine and working great but I rewired everything because I moved it to a bigger control box. now sometimes they will move just for a second or two and then they stop. Ive checked my wiring 5 times along with my power out puts on all supplys and everything is good. Im almost postive its mach3. Ive changed around my step,dir pins and I can get them to run in one direction, Other times they buzz. Ive played with motor speeds and active lows but still nothing. I figured I would ask for help before I start jumoing up and down on it.

Did you have it all working in Mach3? Have you looked at the videos at http://www.machsupport.com
It sounds like the acceleration may be too high, or their is noise on the step and direction lines.

I had them working with mach3. I tried all speed settings. They only make sounds some of the times most the time nothing. I did change the type of wire I used do you think that could be it.

Also the motors are not lockingup all the way. They get harder to turn when the controller is on but I can still turn them. Before I couldnt turn them at all.

Alright I played around and stripped it down to only one axis wired. I got it working in one direction but now I cant get it to go in th reverse direction. Would that mean my dir signal is messed up? I did try switching pins to.

[moto21]

I rewired everything with more direct routing. This seemed to help some. I played with the program a little and now I have all 3 axis moving in one direction. Im running in active low and the pins are defualt. any ideas

[ger21]

increase the direction pulse width?

Replace the breakout board, I had the same problem!

If you have a break out board, bypass the unit and go direct to the Gecko's.
There is a post with a really great wiring diagram that you could use to reference:

Have you tried to check the voltage at the motor windings for the reverse direction, or even swap the coil for the one that works to the reverse direction coil?

Well I got a new breakout board and that didnt work. I even tried wiring it direct and still only one direction. I starting to think it mite be the geckos. Any new ideas.

Put a separate supply voltage to the dir pin on the gecko manually.

[moto21]

you mean another 5vdc line directly to the dir pin.
