I am a new shopbot owner. I got this idea that I can engrave with it. I am having a lot of trouble with the integrity of the letters. For instance the 8's or the o's are very deformed. I have bought engraving bits down to .015. I am trying to use a .030 bit. I also used a 3/32 end mill bit. The first time I did it the letters looked ok. But now it seems no matter what type face I use the letters come out lousy. I can literally see the bit jump and move as it cuts the letters. Like on the edge of the upper left portion of the 8 the bit will move ever so slightly and cut out a portion of the letter that it shouldn't. I know this isn't a lot of info but if you could help a little I would appreciate it. I have a porter cable router on the 4'x8' prt shopbot table. I am using the Rowmark 1/16 plastic engraving stock.
I have 187 of these 1" x 7" plaques to make and I don't want to be held hostage by the engraver that I usually use. He takes forever to do anything. I figured that I could get these done by now.
Thank you!
