Brother TC-225 / TC-229 adventure!

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.

The belong to "milltask" and have been there since version 2.6:
linuxcnc.org/docs/2.6/html/man/man1/milltask.1.html

Though there are more in 2.7:
linuxcnc.org/docs/2.7/html/man/man1/milltask.1.html

"milltask" is (indirectly) loaded by a reference in the INI:

[TASK]
TASK = milltask

I think that there was originally an intention to have different versions of "task" for different applications.
Note that milltask is user-space. This means that it might well not update reliably if you change values from G-code.
(And it isn't clear when the system updates its internal opinions from the values).
You might well still have to use the "W extends Z" approach.

hmm.
