I have started a Cnc laser cutter with the hopes of building something good enough to cut SMD solder stencils.
Laser head:
I started with a 300mW IR laser salvaged from a CD burn; later I bought a 1W IR laser off ebay and a glass focussing lend. I turned a holder for the laser diode; and mounted it it in aluminum heatsink. I put the whole thing on a CDROM sled mounted on a ink jet printer carriage
Pics and video below.
For the driver I'm using stepper control modules from Pololu; I have laid out a carrier board for them and sent it off to be fabbed; should be in next week. Fully optically isolated; two relays for spindle control; 3 inputs for limit switches. Provides upto 2A of current per stepper coil (up to 35V)

Wow is just the simple word that may explain that how much I liked it. It was nicely stuffed with the material I was looking for. It’s great to be here though by chance.Laser cutting machine price
