Setting up a plasma cutter and looking for some help.

Oh by the way I did find a bug in the PNCconf wizard. If you tell it you have a para port and then on the page for that para port tell it that it is set for input it ignores it when you actually write the files. It sets the pins correctly but at the beginning of the hal file I have to change it from "out" to "in". And of course because the wizard overwrites any changes I have to do it every time I rerun it. And I ran it a lot setting up homing and limits.

You should report this on the pncconf section of the forum.

Done.

So this is the mag head. Currently looking to see where to put the break away switch.

While looking for a viable break away switch I did find a stack of dc opto relays So thats good.

Quick question. Can the breakaway and home switches be the same? I am not using limits on z.

The switch on that linear stage is a www.ia.omron.com/product/item/2229/ which senses when something is passing through its slot. I plan on attaching a piece to the head so that it is in the slot all but the very top of Z. Only time it should come out of the slot is if it breaks away or during homing. This sounds viable but I figured id ask before doing it.

There is a pin joint.N.homing which goes true when homing.
I would try using and2 with your input and this pin and use the output as input for the homing signal

Typos excluded, something like this (excluding loadrt and addf lines) then use the mysensor signal for the float switch input

HINT: I always like to check the function of a new pin (eg. joint.3.homing) in hal show before doing something like this to make sure it functions as expected.

If you are already using and2, you will need to add an extra instance of it which might change the index (eg. and2.0 might become and2.1)

Using names for them sorts this out, it makes for easier reading as well.
