External Jogging

Thanks. Sadly that config is very complicated and needs exactly the right hardware and all your custom components.

Back to trying with the sim, I think.

Spend a lot time to get this machine to run

I can tell.

Even testing the jog is tricky, as you seem to be jogging with the parport?

Is it screen-jogging that causes the problem, or parport jogging?

If I move the Axis by Keyboard ( Cursor up down left right and picture up down )
all is OK
Only with the buttons ( conected by Parallel port ) the Y Axis move instead the Z

The keyboard and HAL jog commands take a different path through the code.

Can you confirm that when you attempt to jog Z that the pins

halui.joint.0.select
halui.joint.1.select
halui.joint.2.select
and
halui.joint.0.is-selected
halui.joint.1.is-selected
halui.joint.2.is-selected

Show the expected values?

I am going to try a simple version, but it is quite likely that what I remove will be the critical bit..

but Y is moving

Which axis.n.motor-position-cmd pins change value?

OK, I have managed to reproduce the problem.
I think this is good news for you.

I am now changing to 2.5 to check that it isn't a problem there.

that means you find the Problem?

I have found that there definitely is a problem. I haven't found the solution yet.
It looks like Seb did a lot of hacking last night, and has located the commit that caused the issue, but we are still not sure why:

Might make interesting reading.
