We are looking at options for digital air pressure indication so we can accurately repeat pressure. Looks Thunder at one point sold this, however it is no longer for sale that I can see.
Does anyone have experience adding an air pressure readout? Thinking something line the SMC ISE20:

If you don’t absolutely need a digital readout, a simple air flowmeter might be better. I added a flowmeter with my solenoid-controlled dual flow air supply along the lines of Sadler’s example:
The stock air pump in my OMTech 60 W laser produces only a few psi, so a pressure gauge doesn’t have enough resolution to accurately indicate the air flow, particularly through the low-flow engraving path.
Bonus: the little ball rattles when the high-flow solenoid opens, so I know it’s working!
That is a thought. We are looking for a value to set to so we aren’t doing it by feel. thanks!
