You can use logic components such as and2 to connect multiple signals to one. But I'm not sure I see the advantage of doing so with an e-stop. Generally an e-stop loop is all in hardware, and the e-stop input to Linuxcnc is merely to inform it of the loop's state.

I could use this PDF manual too - if it even exists, of course.

What was the doc pertaining to? Maybe the information can be found elsewhere?

Linuxcnc allows you to create a Python filter that processes the Gcode when the file is opened, Not sure how qtplasmac does it.

Yes, sorry its gone. I'm working on a similar document for Trixie. Its still a draft but its here

There is a small charge for it AUD $2 to cover costs. That really only covers the payment processing costs. I will send final versions once its complete to anybody that buys it while its in draft.
Its hot off the presses as I just wrote it today. Any feedback will be appreciated.

i have an Old Abb irb2000 thats just sitting there, that i want to revieve.
it seems that this could be a way forward.
What kind of setup are you using for the rest of the control chain ?

estop-latch is the right way to go  with these but a better way is to use joint.N.amp-fault-in IN BIT   Should be driven TRUE if an external fault is detected with the amplifier for this joint.

This will halt motion.
Your drives may also have a estop input which disables the drive on an estop.

Perhaps the information in this post would be helpful for you.

There's a couple of ways, you could use the Mesa Configuration Tool or you can add the estop_latch component yourself.

I'm not with the machine right now, so cannot run any tests (perhaps later today) but looking at the various hal state dumps I posted previously, spindle-at-speed seems to be showing false all the time, whether the next move works or not.
It does look like I need to check spindle-at-speed, but it doesn't seem like it is the deciding variable (at least not on its own)

Hello,

I am running a thre axis CNC mill with stepper motors with mesa 7i76eu. I wanted to connect stepper driver alarm outputs to mesa and have them triger emergency stop. I am also planning on adding two additional Estop buttons. I wired them up but then noticed that linuxCNC setup wizard only lets me select one output as emergency stop. Is there a way I can select multiple inputs as emergency stop, or do I have to wire the buttons in parallel and connect them to one input.
