[Tom Mccullough]

Can anyone instructions/schematic of how to properly wire an e-stop on a DIY CO2 machine?

Tom,

PM’s don’t seem to work for me here.

I’m in Bennington Vermont. You cAn give me a call if like, 802-379-6252 or work # 802-585-6425.

I am a master electrician, state electrical inspector and have wired many automated production and packaging machines.

To call what is on these machines a Safety E-stop is a stretch! In the world of machine building the way the E-stop switch is wired is definitely not a safety circuit. It can interrupt the laser operation if nothing fails, but does not have the redundancy of a true safety circuit that would be required of a machine manufactured in the U.S.. I have retrofitted mine with a true safety relay and dual contact E-stop switch that will disable the laser and servo movement.
