B4 my laser crapped out, I was cutting 1/4 bluecor (fan-fold foam) at 60 ipm at something between 20-40 watts Co2 flowing gas laser.

closer to joy... AC servos are somewhat tuned. I get 200 in/min and 30 in/sec^2 acceleration.

Back to calibrating laser power/machine speed issues.

I have cut (though not real nicely) up to...

Get ready for an education and $$$....

Basically, lasers are "moved" similar to plasma cutters, so think plasma table (which ever size you want, mine has 2'x4' cutting area).

Next, consider...

The use of papermask is intriguing...

Yet, now a question remains concerning burning....

Ok, I'm an official lurker as I wanted to make sure I could do what I thought I could do...

I have a laser table with 2'x4' capacity, vacuum table, ac servo drives, and a flowing CO2 laser..
