I'm sure it was user error, but need to find out how to correct it.
I created a part in Solidworks that is 10" x 7 5/8". The width of the "edges" of the part is 1/8" wide, and all corner radii are 1/8" to match a Ø1/4" diameter bit (pic 1). Next I saved it as a .stl file.
Imported it into Cut3D and sized it correctly. You can see the results done in Pine in pics 2 & 3. Instead of smooth lines along the edges, you can see where the router bit stopped and started. It left a bunch of curvy arcs instead of smooth ones.
Not sure if it's because the roughing pass was skipped and it went straight to a finishing path.
Here are the bit perimeters used on finishing pass:
Ø1/4" bit
Pass depth: .2"
Stepover: .1", 40%
Feed rate: 100"
Plunge rate: 30
Raster angle" 45°
Cutout toolpath was the same.
Is it because there was no roughing pass, or what else looks wrong? Also, what is a good feed rate for a roughing pass and a finishing pass? One last thing, would a horizontal or vertical pass have been better?
