I had the time to get the unit out of the box.  I did find that two of the four caster wheels on the bottom were knocked off during shipping.  Also the final mirror was knocked off of its mount, with the mount bent.  I had time to reinstall the wheels, hope to straighten the bent mount tonight.

This mirror is simply the guiding mirror or is it the exit mirror of the laser?  I hope , for you that it is the former.

Electrathon, how is the build of the laser coming along?  I am hoping you will have some good info on that machine for us here in the very near future.

Thanks

I have been rearranging the shop and building a table as a permanent location.  Once that is done I will address the operation of the unit.

I got the bench finished that the laser will reside on today.  On to the next step.

Funny that this popped up today in my feed as I missed it when it was posted. I happen to be purchasing a laser engraver today. It's going to cost a wee bit more than that setup but i'm anxious (and a bit nervous) to see what I can do with it. My intentions were it to serve as a "ghost employee". Loading projects up, hitting send to printer and me going back to doing leather work while it's engraving something else. I have a spot picked out and all but a vent cut to exhaust the fumes. Please take ventilation into consideration if you end up engraving any plastics or metals. Leather stinks when it's burnt, but all the other stuff emits nasty stuff when engraved. Best of luck!

I used to work for a small Norwegian company that built and sold laser machines. We also did laser shows on advents/ big music advents etc. That time we used mostly tube lasers for big events, they needed a lot of power and water. The modern YAG (diode) lasers was still not powerful enough. These cutting Co2 lasers are puls lasers and that's what's make them that powerful. But I remember we had a 40 watt argon (tube) green laser that burned true a plaster wall on a steady beam. I know these tubes have a limited burning time and if the water supply fail you have big trouble. However, it's funny how cheap they have become. I think you should be careful about moving these around until they are cooled all the way down (if thats neccessary for one reason or another). That time there was only one computer program for lasers avaiable. That was made for Windows and we used windows bitmap pics on graphics, logo projection etc.  Good ventilation and steady water supply is neccessary of course, always use safety glasses. I does not matter how many mirrors the beam is reflected true, it still travels to the "moon" and burn your eyes. I remember we had to alert and have permission from air traffic control for outside events. Remeber, it's serious power. I look forwards to hear more about how these inexpensive units works out. Good luck
