Help with setting up 6XD CNC for the first time

p8blr

This is my first time setting up a Duet flavored CNC and I'm needing a bit of help. So far I've been able to get my spindle to turn on and off with a M4/M5, but I can't get my axes to move.

The machine is a Indymill build and I'm upgrading from an Arduino running GRBL.
Stepper drivers are RTELLIGENT T60's wired exactly according to this diagram: Duet6XD Wiring (I tried with and without connecting the alarm wire but no difference)

GRBL settings:

Any help would be greatly appreciated!

@p8blr ~~I don't see a M906 command to set the axis motor currents in your config.g file. This will cause the drivers to give them only a few tens of milliamps, not enough to move them~~.

p8blr

@dc42 How much current would you recommend for external drivers? I actually had it in there and removed it because I thought it didn't apply to external drivers.

Here it is added in there and unfortunately it still doesn't move the axes. I can see the status light on the drivers come on but still nothing.

@p8blr I'm sorry, I missed that you were using a 6XD.

Ordinary moves won't be allowed before the axes have been homed. To test the axis motors, first send G91 to select relative movement. Then send G1 H2 moves, e.g. G1 H2 X10 t move the X axis +10mm. These moves are allowed even when the axes haven't been homed.

Another thing to check is that the drivers are enabled (so the motors will resist turning by hand) when you send M17, and disabled (so easy to turn by hand) when you send M18. There is a jumper on the 6XD to set the enable polarity.

@dc42 Thank you so much, it was that jumper that did the trick!
