hey guys, does anyone here have any experience with the roland egx line of rotary engravers? I have been trying to figure out how to use the end mills, and whatnot and cant seem to get the speeds or feed rate correct. Im using a soft plastic to try and cut out of, and it keeps breaking the bits off. I have 1/32 and 1/64 bits, so they are very small. Any help would be awesome! Trying to cut out some pretty intricate things, and its impossible to do with the profile cutters. I did check out the www dot2linc.com site and they have a bunch of nice tools there. Anyhow, any help at all us much appreciated.
