Its been a while since i did this, but I think you are close.

Some named parameters exist without the prolog code, look in the G-code parameters docs.

Ok m6 tx working perfect. Adding on z motion now.
How do I move the z soft limit on the fly?

I can't find the reference I saw before. On my phone in front of the machine googling. Haha.

while were on the swapping limits... swapping to servo spindle mode or the equivelant for orienting...

ive looked at the drawing, it makes sense I think, but how do I implement it?

Linuxcnc wont let me assign 2 axes to one output, so clearly that's not the way its done :P

thanks

I can't find which module they are documented in either. But I imagine you would use these pins:

O_o

now I'm just more confused, haha.

so,
ini.2.max_limit would be our z axis upper soft limit which we could change on the fly from the toolchange subroutine?
ini.z.max_limit is also there. odd.

while were at limits... when I home the machine, randomly, on any axis, it will occasionally give an f error. the machine is finding the switch, then the index. it always give the error when hitting the index.

any thoughts? at the speed its running, I cant see how it would be exceeding the f error, especially since it never does at any other speed.

is the per axis index_enable signal wired to the PID component?
If not this can cause a thump when index is detected

Also I've seen this when the thread order is wrong. Handling index detection is a bit tricky since the position
is zeroed when index _enable is true and the index is detected.

all I did was check use index in pncconf wizard. ill have to check the hal/ini to see what its actually done. there definitely seems to be a thump though.

Ok on the homing.

After setp stuff the next line is about using index.

Net x-index-enable <=> pid.x.index-enable

Should this move?

Now how am I dealing with the z limit. I don't see the pins andy wrote in there already. Where would I ad it and how do I use it? Thanks.
