I am having trouble with the extruder in sb3. I tried calling shopbot and they did not seem familiar with the tool. I am trying to cut an arched casing from a sheet of MDF. I will attach the I saved. I was unable to post the vcarve file so I will include a pic of my screen. In the extruder i am using a .125 ballnose bit. The x and y radi are 67.355 degrees. I was centering the x axis at 48" and the Y at-50 inches and cutting from 320 degrees through 40 degrees. I think the arch is correct I just cant get the profile correct. I have been zeroing to the top of the material.
Thanks for any help
Todd
