So my air compressor died at the start of a long cutting job, the compressor didn't stop running, it just had 0 output pressure. I didn't pick up the problem until after the job had finished, 1 hour of no air pressure out of an air cone means 1 damn good, expensive lens ruined. This isn't the first time this has happened to me and I'm now determined it will be the last. I'm going to add a pneumatic pressure switch into the laser circuit, I don't think putting it into the 240v supply line is a good idea so was thinking of splicing it into one of the interlock switch lines, no air pressure therefore no laser beam.
Anyone else done this and maybe placed it elsewhere?
