some power tests?
Quotesome power tests?What do you mean?It's stated as a 40W tube (maybe 40W if I keep it a decent cool temp) and it seems somewhere near that from the holes I've made so far (I've used a 60W and an 80W laser cutter before).The unit itself is rated as 250W but I'll measure that at some point when I have it running.
My only concern so far with your mods is the replacement of the window; that amber color is likely a filter for the wavelength of the laser, so that any spurious reflections while looking at the cutter work don't damage your eyes. Then again, that's just a guess (based only on using special safety glasses/goggles with a 200mW green laser pointer).I might have to check ebay again - see how much the prices have come down since I last looked...Well, I just looked - and prices are down; really down since the last I looked. Your particular machine costs about $800.00 USD (+s/h); 40W laser tubes can be had for around $150.00 USD (+s/h). Much better pricing from when I last remember; of course, those prices are "drop-shipped from china" - and I don't quite trust dropping nearly a bill to a chinese supplier (I might be willing using escrow, though - did you use an escrow service?). I did find one guy selling from florida - but he only had local pickup (no shipping). Interesting, all the same - can't wait to hear how your mods and such turn out!
