Hi,
The items in cause are Nema 34 motor 5.6A, 1200oz-in, and driver DQ860MA.
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.

In mach 3, in ports and pins, motor outputs, checking only the enabled column does nothing, as I,ve seen in some tutorials. Checking only step low active will get the motors running, and also checking both dir and step low active, seems to work.

In config, motor tuning, I,ve set a few different speeds and acceleration just to see the difference. What exactly should I set in there?

Now, I,m new to this, and I,ve surely missed something, as the motors get relatively warm after a 1-2 min of running a test gcode from the default mach3 folder.
The motors are not connected to the ballscrews, so there isn,t any load to carry.

What have I done wrong?


Regards,
Andrei
