Wire an air pressure sensor switch into the e-stop circuit, same as you
would any other
Pete,
look at the toolchangers we did for the orac and triac.
and the interaction between stages to see that each is completed ,. far far
easier than remap
in fact i hate remap , but i dont know why if i'm honest , it just does not
seem to dig deep enough .
and even the triac and orac changers

It depends.. For that toolchanger, definitely.
For a rack-toolchanger that

Indeed, but I don't have one. The entire mill was built around three

One way should be run multiple instances of LCNC (Xenomai rt patch I heard
about). On commercial CNC is possible have multiple CNC channels that can
share informations between them.

Still working on spindle orient but that will be the next step. Connor
seems to think he has a solution for this but we have yet to try it out he

Yes, I think you are a prime candidate for a G-code subroutine that

Well we have a low pressure sensor already in the machine and it is not yet
implemented in the toolchange setup but it will be. Now not sure what you
mean about the G-code subs is that remap? what actuators are you talking
about? Detecting failures is already built into the machine with

Coding a timeout in G-code should be easy, though I have never tried.
M66 (for example) sets #5399 if it times-out, and the remap structure
introduces both the (abort, )
