Laser crosshair

Postby woodworker2001 » Sat Nov 19, 2016 9:56 pm

Designed this for a laser crosshair for the table at the school I teach at. 3D printed and bought the two 5v line lasers from eBay. Haven't had a chance to get it wired to see how it works but clams up nice and seems like it will work.

How are you going to deal with the smoke and spatter of piercing?

Why pierce it when you can punch it!

We shall see how it holds up to the sparks.
I appreciate the info on wiring. I am not running Mach 3 though. I just wired it to an old phone charger that puts out 5v. I have run it a couple times and seems like it should be ok.
