Ok, Its now alive. Thanks to all that contributed. As stated the DIR- wasn't connected so I bridged it with PUL- and I'm now in business. Its a pity the wiring schematic didn't show it and I didn't notice the slave axis as Im not using it. Some finishing touches through the week and I should be making dust by the weekend..........................Hopefully.
Thanks again
Carl

The drives come pre tuned and I think they sent that cable in the kit. That is the company I purchased everything from and hopefully will be open tomorrow for some support.
Thanks for looking

I have re wired everything and checked again. Interesting that you mentioned about the earthing as the DIR- post has nothing mentioned in the company diagram of which I have followed except for the slave axis. Is this the key to my solution? I have attached a diagram, not sure if it will work. I'm not forum/PDF savvy.

I have tried your suggestion and the voltages are what you said they should be. I also adjusted the pulse width too, with no results. Back to google and pulling my hair out.
I forgot to mention that I am using an older computer with XP if thats of any help

My Name is Carl, Just nearing the completion of my first CNC Router. I'm a Fitter and Machinist and love DIY anything. I have owned a CNC Plasma in the past and operated CNC Lathes. I'm looking forward to getting this thing going once I iron out a major problem (posted in other area). I will frequent here regularly as I do with other forums relating to other interests.
All the best and MERRY CHRISTMAS.

General Mach Discussion / Steppers will not reverse

« on: December 24, 2014, 04:22:20 AM »

Hello all,, let me begin by stating that I am quite fresh to Mach 3 having just purchased the full licence tonight. I am nearing completion of my 4 x 8 router and cannot get the steppers to reverse in the MPG screen. I have searched the web,youtube etc with no results. Both keys + and - on the vitual handpeice spin the steppers in the same direction on all three axis. I am running Leadshine encoders and the steppers rotate in both directions when in test mode. I cannot get any support from the company that I purchased it at the moment due to the time of year. I have also been through the pin menu a dozen times and I'm at my wits end. Sorry for the first post request, however I intend on doing an intro later with a few pics. All the best, thanks in advance and MERRY CHRISTMAS!!!!!!
Regards Carl
