Wiring diagram on my old 1300x900 laser... in process

[Gene Uselman]

I have sold my old laser to a friend and will be supporting it as long as I hold up I guess. The good news is he is the same age as I am so we are having a race to... the end I guess. The wiring was pretty funky on this machine and four years ago I don't think the Chinese were very concerned with our wiring problems, they have... improved, but still there are gray areas between what flies in China and the US consumer. I have never found what I considered a good wiring diagram for a laser other than Brother Tim in Oz and he is dealing with the virus and trying to protect his family and has larger problems. I know enough about wiring to have stayed alive so far after wiring in my commercial building for 25 years- but electrocuting myself and harming some other soul is my line in the sand. Hence my attempt at a good reliable schematic for this machine and also the one that is replacing it [with a different Ruida controller]. I am going to post this and update it as I make changes. This machine is 220V and the new one is 115V with a transformer to boost it to 220V single phase, so basically both are wired to run on 220V as China and most of the world seem to have as a standard. So here we go...

This is a jpg of my vector wiring diagram, so when I get farther along I will make the vector files available to anyone who would like them- they should be a good stepping off point for someone who wants to customize them to their machine. I will be connecting the 220V building power to the main diagram of course and I have separate detailed drawings for my version of Russ' Ult Air Assist and my control panel buttons.

This is my Air Assist system which has evolved over the years. I cut/engrave many things, many prototypes, and rarely do the same jobs over again. I often do not have the AAssist enabled when I want it and often have it enabled when I don't need it. By wiring the wind pin to my control panel [coming in a later thread] I can either turn off the AA if I don't want it [off switch] or turn it on if I need it [on switch]. I know... minor, first world problem... but it can be fixed, so why not? The LED indicator light is a good reminder of what you have set [I don't hear well so sometimes if it is noisy I cannot tell if the higher level air is on].
