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
