Laser Material Guidelines

The goal of this page is to give you a good starting place for speed/power settings for various materials. The values were determined by looking at the average values from the laser logs (which is one reason why you should log your work).

If you see something that looks really out of range with its neighbors, probably bad data entry, so use some critical thinking skills. I tried to do some basic sanitation of the data, but no promises on completeness.

Also, this won't be well formatted because it's too much trouble for me process and gather the data, and then write automation to deal with wiki table formatting.
