I've searched and read everything I can here on acrylics. From what I gather:
- Either burn the back side if it has transfer tape/brown paper backing (and reverse image)
or
- Place acrylic on black paper and focus on paper (no need to reverse)
- Burn full power
- Feed rate I've seen various posts, ranging from 30 - 150mm/s depending on the laser wattage.
My question to you guys, is that feed rate correct? If so, a burn very big will take forever! I loaded a simple image last night, about 6" square, raster, and at a speed of 30 it said 17 hours to burn!
What feed rate do you guys that have a 2.5w laser burn acrylic at?
Thanks!
