It sounds like you should at least boost your power to 100%.

What Frequency are you using for vectoring?

You might want to experiment with some higher frequencies. 500 is what I use for wood. For acrylic I usually go up around 2500-5000. I haven't done much Rowmark, so haven't spent any time experimenting. ...Dave Dave Jones Design

Gary, quote: Also, I have been using flourescent fixture "eggcrate" for my cutting grid. You might want to check the content on the "eggcrate" material - PVC is very harmful to the machine & humans............... It also burns and has a lot of "crud" buildup and in general, messy. "I know, been there and done that". You have already seen that one of our forum members sell the grids, and so does: www.benecorinc.com - these have no frame around them, just an "insert" if you will. ~ John http://www.creative-awards.com creativeawards@msn.com

Funny, I never even gave it a thougth as to what the eggcrate was made of... I'll check into it - hopefully it isn't pvc!

Anyone know what they are made of?

Also be sure it is not styrene. My two laser fires were caused by that. The beam goes out of focus as it goes to the bottom of the grid, and styrene WILL catch fire eventually.

I am now using Mike's grid and find it very good.

When you finally understand it completely... it changes.
