Unwanted overcutting advice please

Hi Lee,

It's a Spartan 1313 "from" Mantech, ive attached a generic image as I'm not with the machine right now.

I don't push the machine hard, cutters and material are expensive and I'm not trying to get cycle times as short as possible, certainly not in the case of my example photo as far as I know. It was only a 2mm cutter so I was taking it easy, I'll need to check what my feeds and speeds were.

CAD/CAM is Vectric V-carve 11.5.

The corners are sharp on the vectors but V-carve (should) automatically adjust the toolpath based on the cutter diameter to cut a radius in a corner the same as the cutter radius. (Though I'm sure you know that!).

I could do with running some more tests to see if I can establish if it's the machine or the operator but I'm so busy and time is running out I was hoping it might have been a common issue with a relatively straightforward cause. (Is it ever!)

Ok, try the same settings again but this time actually make the internal corners radiused (filleted) for the 2mm cutter, a 1mm radius should be great. I would then say its a hardware issue if the problem persists.
