We found a problem cutting our masks w/ a laser. The edges of the mask are burnts and weakened. this cause a erosion of the mask which is not even. I would use a photo resist. Or have the masks cut out with a plotter cutter.

Sounds like you are using masking tape, is that correct? We use a Poly film that is safe for the laser and and it has never burned the edges.

No. We use a poly vinyl film.
I would be interested to find out the laser rated film you use. It could come in handy for some of our projects.
Thank you for that information. Much appreciated.

If it is a poly vinyl it is probably PVC based which is a definite no no. The fumes creared will damage the laser.
We use Rayzist's LazerMask. We have a 40 watt laser and use a setting of 60 speed and 100 power which according to Rayzist is overkill but since it works for us that is what we use.
Hope this helps,
Dave
