Hal configuration 7i96s + 7i85 + whb04-6

Are you using encoder position feedback?

( Because a stock hal file / firmware will not work if stepgen feedback is used )

I use stepgen pos feedback. I put encoder feedback there once and one of the axis liked to wander as (i presume) it tries to do the pid loop in lcnc while it is being done in the servo drive. The encoder signals are hooked up however.

If you use stepgen feedback and standard firmware, homing to index will not work
as the stepgen feedback position is not cleared on index like the encoder position.

To use index with the stepgen, you must use firmware that supports a stepgen index.
(7i96s_7i85dsdi.bin for a 7I96S+7I85) This may also require using LinuxCNC master.
In addition, the hal file for this configuration must use the stepgen index enable pin
rather than the encoder index enable pin.

I just tested this and it works great!

I finally got both my Y axises hooked up again.
But i expirience an issue with tandem homing and Index homing combination.
The index homing works well on my X and Z axis. but on Y axis it does not work well.

It does the normal tandem Y sequence, finds index on Y, stops Y tries to find index on Y1 (but y1 is standing still, but mesa thinks it is moving. Eventually you just get timeout or out of rang error for Y1. When i disable index homing, it works well. Any idea what could be wrong?

Did you manually verify index operation on both Y and Y2?

Did you intend to have index homing enabled for Y but not Y2 in the ini file?

 Could the "ASDA Gantry mode" interfere with LinuxCNCs homing?
(normally LinuxCNC would handle all homing operations)

I commented the Gantry mode part out and it was still doing it wrong. But I'll double-check on the Delta servo control software.
I will also double check if the index is working well on Y1/2. This would ignore any of the Y1/2 commands if it is on tho (as it just regulates itself vs Y).

Did you intend to have index homing enabled for Y but not Y2 in the ini file?
When I was doing it; I put them both on YES; It might have changed by the time I uploaded it.

I will double check.

Nevermind it seems to work. I configured an IO incorrectly so the gantry was always in GANTRY mode.
Now it seems to work :")
