Dip switches set as OFF OFF ON ON OFF ON ON OFF , which sets the thing to 4.9A Peak, 3.5A RMS, Full Current from SW4 (i don,t really know how to set this), and 2000 pulse/rev. The next current setting is 5.7A peak.

Nema 34 motor 5.6A, 1200oz-in, and driver DQ860MA.

motor turning: acc at 50 velocity at 300 for the y axis (whole gantry), cause at a full stop, it does not shake the whole thing, and 400-500 velocity for the x, seems to not cause trouble.

I took apart the whole thing, and have it on my desk right now. I connected one stepper only directly to the driver and it works ok, but still it seems to lose a few steps here and there, at various speeds.

I.ll use it next with the long shielded cables and see how it works.
Will post some results, photos, videos soon.
