Cool, thanks! I'll see what I can do.

If you're out of analog inputs (FRO & SRO already used), you can get pressure switches in various psi values instead of analog pressure transducers. A switch can turn on (or off if it's NC) a digital input on your BOB as a pre-M6 safety check.

Some are 2-wire, and some are 3-wire like proxys.

I'm out of analog inputs on mine, so I'm using an 0-5v miniature voltmeter with an alarm output. Transducer is hooked up to the panel, and the panel alarm goes to the BOB. I'm interested in knowing the pressure, but I don't need UCCNC to care about (and display or calculate) the pressure as long as it's above minimum.

Nice job on the ATC, by the way.

Some of the big routers I've used have had the air pressure switch as part of the E Stop circuit.

The old axyz didn’t have an air pressure switch
I saw the transducer on eBay and it got my interest.
I realise it only needs a switch but come on - having a psi guage on screen for £12 is pretty cool
Even if you only know how long until your compressed air supply is up enough to go !
I love how easy it is to add stuff to uccnc .
Ps use an arduino mega via modbus and get a further 8 analog ins if required

hi, I'm also putting a transducer to read the pressure on the screen but I don't understand what Getvar (150) reads in your macro?

set analog in1 to var#150

the macro then reads that var#
