I bought this set from Ebay:
3 PCS Wantai Nema 34 stepper motor 85BYGH450C-012 ,with 1600oz-in dual shaft i
3 PCS Wantai Stepper Driver DQ860MA with 80VDC,7.8A, 256 Microstep,
3 PCS 350W,60VDC,5.9A Power supply,
1 PC Breakout Board,
1 PC DB25 Cable.
I have a lot of difficulties to get it work.. Does anyone have this same kit? I should have everything wired correctly, it wasn't easy as i got 3 different wiring diagrams. I use my Ibm thinkpad t41, and mach3. I got this set work for short moment, and without a reason it stopped working again.. It works super slow speed now.. For a moment it was "fast". Sherline 1/2 pulse mode is doing some problem i think. Sometimes when its on, it works good, and sometimes need to change off to get working..
So if anyone have this same kit, I would be happy to get some tips. Thanks. I have tried so many different settings.. tried many different set from driver (sw1, sw2 etc.)
I am building a cnc machine with these dimensions: X=3000mm Y=2000mm Z=1500mm. I use pro rack and pinion sets from cncrouterparts.com..
Also 2,2kw watercooled spindle motor.

What it would be better you have posted prior to purchasing those beefy motors. Nema23 ~380Oz-in motors would be enough to run your X3.
