So I’ve recently started using PVC after @SteveMoloney showed off some excellent projects and gave me some wonderful tips. With PVC, I’ve noticed that I’ve gotten some unusual ridges where the bit stops and meets another bit stop. This spot that I’m talking about is in the image below, with RED arrows.
You can see this clearly in the finished carve images below:
You’ll see that the ORANGE arrows I put in my first picture actually carve through a section (as the bit does not lift), to carve out a tiny section at the top right of the 7.
Anyone have any tips? @SteveMoloney - Have you run into this?
It’s PVC board, so I’m doubting that the material is uneven (as it carves completely into the material…if this was the case, I’d expect a difference in height from one side to the other).
I’m using a 10% stepover, and used a 40% stepover in the image below (different carve).
You can even see above the stars above the RED…they were a different workpiece, so the machine was re-homed prior to that carve.
