Hi
Could anyone tell me briefly how the Low air pressure input works on the latest version of CNC12 , i have searched forum threads but can't find anything.
I'm still running the previous CNC12 version but suspect i may need to update to get this feature.
In brief i am running a homebuilt ATC on a small lathe that uses a pneumatic cylinder to open and close.
I want to add a pressure switch so i will get a warning if the pressure is too low to fire the cylinder , most likely as i have forgotten to turn the compressor on !
Ideally any program running would pause and i will get a warning message come up in a dialogue box before rectifying the situation and pressing start to continue ,
Does the "low pressure input" in the latest CNC12 version work along these lines ?

Re: Low air pressure input
From Acorn CNC12 v4.20 Acorn Wizard Input and Output “canned” PLC functions and M codes:
Input for Low Air Alarm, issue message when input is Active, finishes current G code job (does not stop current Job that is running).
works just like low lube….issues warning message, continues to run until job is complete

Ok , that's great thank you
looks like there are 2 options , issue a message and continue to run or issue a message and goes into E stop mode.
Ideally i wanted to avoid going into E stop and just to pause , but an E stop would be preferable to continuing to run.
I get the impression you can not modify these 2 functions in the PLC , can anyone confirm this ?

Re: Low air pressure input
You can modify the PLC program to do most anything you want, as long as you can define what you want.
If you want to stick to what is built into the wizard and the standard template, then of course you are more limited.
