Starting over

The setup works on the parallel port but the same basic values are incorrect in the pncconf version. My pncconf assignments match the suggested configuration.

In this version, X & Z do nothing but Y moves the spindle up and down. Please review the enclosed configuration files and tell me where I am going wrong.

If this is for a G540 I would set the steplength on all axis to 2500 minimum (1000 will not work reliably)
If the axis are swapped that suggests that you are not using the proper FPGA configuration

To write the proper FPGA configuration you would:

sudo mesaflash --device 5i25 --write 5i25_g540x2.bit
sudo mesaflash --device 5i25 --reload

and to verify pinout you would:

sudo mesaflash --device 5i25 --readhmid

I realize I could get my existing hardware working after I do endless edits and hammer the forum with questions while you teach me esoteric HAL programming but I'd rather swim with rather than against the tide.

How are you enjoying the journey upstream?

It just occurred to me that we haven't really done much to prove that it is easy. But I am hoping that you are at least enjoying the process?

See it as like skid-pan training. It's not an easy way to drive a car, but you learn a lot about the car.

It is a 540 and I guess the readhmid file above doesn't reference that I uploaded the 5i25_g540x2.bit file. I'll try those steplength values.

I watched a guy drive a new shiny red Lotus a little too far under a guard rail shattering the front windscreen into smithereens. His rage at his ineptness was close to seismic - I'm not quite there yet.

The enclosure is the mesaflash reflash - no issues there, I just enclosed it for illustration - assuming there is not a version issue.

On steplength, 2500 does change a few things; "X" moves the Y axis, "Y" moves Z and "Z" moves X2 (aka A). This is a G540 so miswiring the drivers is almost idiot proof.
