For my laser, I simply am using a IRLB8721. I milled a custom PCB for some easy wiring.

Oh, I like that too. Tiny.

Curious, what kind of laser are you using? I thought I would try to get my L-Cheapo running before I drop $$$ on a different one. I don't really know how often I would use a laser so not sure it's worth the money.

A 2.5 W 12V Laser.
Since the power circuit is all built into the module, there is no power control; simply on or off.

Cripes! That's a nice little laser for the money. Nice an compact. Working out well for you?

I ordered the mosfet and the other relays. Everything was so cheap. I'll repurpose the left-overs for some future jobs, I'm sure.

Yes, that was useful. Thanks a bunch, apspurgeon.

I did a quick test yesterday with curves, straight lines, and turning the laser off and on, and it came out great!

From a foot or more away, it looks like ink was printed onto the material. I was quite impressed.

It's going to be great to have another tool in the CNC tool box; parts can easily be labeled with text, graphics, etc!

Very nice!

I finally got mine working well. I still need to tidy up my wiring. The small 5v relay that you guys recommended from Spark Fun is working great. M03 S10000 turns the laser on at full power and M05 turns it off. Right now I'm using Inkscape 0.91 to produce my artwork with the J Tech Photonics gcode extension. So far so good. Thanks for the help everyone. ;)
