Hey,

One more question.

In the Motors tab under Control configuration, What do I set all the parameters to there ? (Counts per unit, Velocity Units/Minute, Acceleration Unit/(sec^2) ?

Hey,

I thought I had set it to Step/Dir, but apparently not. I set it to Step/Dir in the software, and restarted the drive (power off and back on).
Connected it back to ESS, and we have motion now!

Now I just need to tune it.

Thanks for all the help, Craig

Hey,

Sorry, I misunderstood your question above. I haven't really programmed the drive. I downloaded the software from dmm-tech.com and tried it to test the drive and ran the Auto-tuning.
That's pretty much it. Is there more programming I should do before proceeding ?

I tried to connect the Step/Dir signals to the drive, but I still get no movement at all.

Hey,

Programmed the drive how?

Hey,

I tried to connect the driver, like you said.
If I'm measuring voltage between pin 15 and pin 1, I get 0V when motor is disabled and 13,78V when motor is enabled.

Ok,

What am trying to do with the enable signal? Get 24v output?

Hey,

I tried removing the DYN4 driver from the equation, like you said.
I have connected a multimeter to XD+(poistive pin of multimeter)/XD-(negative pin).

In the Mach4 ESS plugin config, I set motor0 to CW/CCW, and tested the voltage.
When moving X-axis in positive direction I get 2.9V, and 3.5V in negative direction.

Then I tried to set motor0 to Step/Dir, in ESS plugin config, and tested the voltage again.
When moving X-axis in positive direction I get 3.5V, and -3.9V in negative direction.

I tested the Y-axis too, and it's the same.

Ok.. I just tried beeping the pins on the ribbon cable, and it's not the same layout as the Driver.. So I've plugged all pins in the wrong places.
Hope I didn't destroy anything by this dumb mistake. I'm gonna try rewiring everything tomorrow.

Hey,

I should have clarified that better. I have a DB25 to idc26 ribbon cable connected to the DYN4 driver, and then I insert the jumper wires into the idc26 connector.

XD+/XD- measure 3.5V with a positive axis move and when staying in place. With a negative axis move, they measure 2.9V

The enable pin, measures only 1.6V, so that means the motor doesn't even enable, correct ?

Hey Craig,

I've been trying to wire the motors up to the MB2/ESS last couple of days, but I can't seem to get it running with Mach4.
I tried using the USB cable to the DYN4 driver, and that worked fine.

What I've done so far: (I'm using breadboard jumper cables, to connect to the idc26 connector, that's connected to the DYN4 drive)
XS+(on MB2) -> pin11(idc26 connector)
XS-(on MB2) -> pin23(idc26 connector)
XD+(on MB2) -> pin22(idc26 connector)
XD-(on MB2) -> pin10(idc26 connector)
Y301(on MB2) -> pin15(idc26 connector) = this pin is configure as active low on Mach4, for the enable pin
24v(onMB2 -> pin16(idc26 connector) = 24VIN pin on the driver
GND/0V(on MB2) -> pin1(idc26 connector)

Any help on this would be really appreciated.
