The eBay one is interesting. 20 Watts is not a lot of power but the price is right. With the lower power it would take longer or more passes. It would be interesting to find someone who had one? The really big issue is the Seller. I have had Chinese eBay venders lie to me and then the...

Thanks for all the help, I generally find searching and reading is more productive that getting on a new forum and asking a bunch of stupid questions. I known that commercial fiber lasers are very expensive, more than I can justify. Anyway I will continue on with my currant 6 watt CNC project.

Thanks DTR so from what I am now understanding the source of the 6 watt or so LD is pull outs from projectors. So unless someone is tossing or selling surplus projectors with say a 8 or 10 watt LD then there will be nothing offered for sale. Is a higher power laser diode made just for a...

Yes, I saw that elsewhere. I purchased PicSender and since the last upgrade its been great. Also have a driver coming from both J Tech and X-Wossie. I have been to your website and was very impressed. I just hate to spend a couple hundred right now and three months from now there is a 8 or 9...

DTR, as soon as I get this compact CNC project done I think I am going to do a much larger one. What is the largest practical LD available as far as power goes in a 445? What do you see in the future like a year down the road? I am not a kid building a star wars laser but someone who sees the...

Yes maybe a 9 volt power supply would work, or my other thought was the 9 volts a signal voltage to the driver? ... kind of a bit over the usual 0-5 volt.

I am not even close to an expert level on lasers, but been a electrician and in ham radio for over 30 years. There is no way a 9 volt standard battery can drive a laser to 3 watts. Not enough current available. Maybe .3 of a watt?

I own a 50 watt ULS commercial CO2 laser, it will not engrave metal except maybe anodized aluminum. It can mark stainless and polished carbon steel with a special spray applied to the metal first. YAG or Fiber lasers will do what you want, but starting prices for a Chinese machine are about...

I own a ULS 50 watt CO2 laser but I am revamping a 6 watt diode CNC purchased off eBay for portable use. The eBay vender laser control system was C R A P so redoing with one I have detailed above. After getting another non working Chinese driver board from a vender who is on here I have two...

I am working on building up and getting to run a 6 watt blue light diode laser CNC. I purchased a Chinese built 6 watt one on eBay and it worked but the gcode software was really fussy and the image software had a virus, thanks Chinese venders. The controller was a one of a kind, Chinese...
