I have been cutting/engraving a lot of MDF on the laser. I use 1/8" and 1/4" material. In the past when I cut or engraved the MDF it had a nice light brown edge and the engraving were a light brown. Now the edges and engravings are almost charred. Even if I slow thing down. Has anyone else noticed with the MDF purchased at Home depot?
Thanks,
Bruce
