So this might be a simple process for most of you, (electronics isn’t my strong point) but does anyone have a tutorial/instructions on how to add a microswitch to the lid of the laser so it won’t fire if door is open?

I have the 50watt version, k50?

I get the basic concept but want to make sure I do this right.

These are the ones I’m looking at getting, not sure what spec I need so suggestions welcome.

Thanks

I would connect it in series to the enable laser button. Thi switch has 3 legs, 2 of the marked as NC / NA and another COM. You should then connect the NC and the COM to those on the fire laser enable button. NC stand for normally closed so when the lid is closed its enabled

Thanks @Ariel_Yahni_UniKpty , are the ones I’ve linked above suitable?

Yes

@Ariel_Yahni_UniKpty NC normally closed when switch is untripped. NO normally open switch is untripped. NO is the one you want to use for lid switches so when it’s activated (the lid closed) it is in the closed or conducting position. On my Laser power supply, I unhook the G wire going to the laser switch, solder a wire on the wire I just took off, cover the joint in heat shrink, and route the wire to the lid switch and solder is to the NO connector. I solder another wire from the COM on the switch and run it to the G terminal where you took the wire out of. So now the connections are: power supply to laser switch on control panel, to the lid switch and then back to the power supply.

You can also add a keylock in there as well up on the panel. You just unsolder a wire on the laser switch, move it to a leg of the key switch, and run a little wire between the key switch and the laser switch. Putting the key on a hook high up on the wall keeps little fingers from grabbing it.

This is what I used on my 1st K40, and I’m going to add to the second.

@Nigel_Conroy ​ my mistake is the inverse of the naming, ​ @Robi_Akerley-McKee ​ is correct

I like that a lot @Robi_Akerley-McKee ,as mine is in a classroom setup.

You’ll have to take photo’s or draw me a diagram…

No worries @Ariel_Yahni_UniKpty , I appreciate you helping me out.

I’ve already bought the key switch @Robi_Akerley-McKee

@Nigel_Conroy Mine is in a maker space, so being able to disable with key is a plus.

@Nigel_Conroy Tomorrow I will be taking pictures. I’ll post a picture of the keylock hookup right now.
