Well, sometimes it ticks, but so far no movement...

- I finished pncconf and saved.
- Edited hal as discussed above
- Linuxcnc starts and finds the hal file
- Deselected the emerg stop button, and selected the machine power button
- Tried the jog button on each of X,Y,Z. (A is not shown)

When I jog the X and the Z with the jog button, I sometimes hear a tick from the stepper, but no movement. The Y is silent and their is no movement. The console's animation moves along happily - it thinks things are moving, but they are not.

The motors are warm (ie: powered). The Gecko's power light is on and the fault light is dark. The mesa card is pingable at 192.168.1.121, and that is the ip I used in the hal edit.

I've probably misconfigured something, just not sure how to figure out what. Tried to get some help from the debug settings, but they produced no messaging that I could see, and if there's a log I've been unable to find it.

Thoughts?

Thanks for your help with this!

- Bob

Can you do a
mesaflash --device 7i92 --addr 192.168.1.121 --readhmid
and paste the result.
That sounds like having step and dir pin reversed, but in your case that can be done only in firmware.

The most common issue I see with step motor drives not working
is too short steplength

I would set steplength and stepspace to 5 us (5000 ns) as a starting point

And that was it, I now have moving motors!
The original values were 1000/2000, changed to 5000/5000 in the .ini, and off we go.

Thank you, Tom and Peter!
