Hello,
I have not had a bunch of time to experiment, but it seems like all of the signs I have made so far are exhibiting a symptom I can only describe as 'corner tunnels'. My first guess is that my Z depth may be slightly off. If so, it is off the same amount, every time. I am using a Techno Isel gantry router with a touchoff pad that I can guarantee accuracy to at least .005 inches. I will post a couple of pictures so you can see what I mean. Any suggestions would be appreciated. I am sure it is just a matter of getting a few tweaks down.
Also, I am using a 90 degree V bit that is pointed.
Thanks, Mike
