I am about to hook up an air compressor to my 60W CO2 laser (manual connection, bypassing connection to the controller).
THINGS I’VE READ: FACT OR FICTION::
The micro air pump that came with the machine puts out approximately 5psi? I have found no formula to convert CFPM to PSI.
It is better to have the air blowing from outside of the cone as opposed to thru the cone. That does not make sense to me, maybe if the laser always traveled in one direction that could be true.
The reason for an external air supply is that (according to my readings) different materials cut/engrave better at different air pressures. I can only find general information about this. Plexi cuts well at 5psi but engraves well at 35psi. Wood, which is a broad generality, cuts better at 10psi. Nothing about engraving wood at any psi. I have yet to play with any high grade stone, ceramic tile or coated metal.
So my question is: Has anyone produced a chart on the general characteristics of air pressure on various materials, cut and engraved?
I’m 7 months into my laser and still learning/observing. Any advise would be welcomed.
