Hi to all! Some days ago I cut the test tea tray from birch. Everything is fine (almost), but I got a strange “artefacts” (don’t know, how to describe that correctly) cutting arcs parts. Is that "normal"and I just should use sanding paper to get rid of them, or that is because of some wrong calibration? That is not the first time, when I got similar “cut in”. ![](https://canada1.discourse-cdn.com/flex009/uploads/inventables/original/3X/d/1/d10a3f5e469d8bcd66b6a3876a67d6493a01b994.jpg) ![](https://canada1.discourse-cdn.com/flex009/uploads/inventables/original/3X/b/9/b9b7a257242ad2da69ea589c826a0a8e4bc23d1d.jpg) ![](https://canada1.discourse-cdn.com/flex009/uploads/inventables/original/3X/0/4/042f6a25b7375d5502006a245717bf52acdee4b6.jpg) PS. X-Carve 1000 (bought in march 2017), G-Code for 3D tray sent from Aspire, cut in Easel. ---

Thank you. Will check geometry and belts today. Just not sure about how tihjt belts should be. (will try to find now in forum threads) ---

Use 3d tabs to stop getting tab witnesses If you have a single line, that’s dwell plunge and the cure is ramping your plunge (another toolpath option in aspire) ---

> [@JeremySimmons](#): > > Use 3d tabs to stop getting tab witnesses will try that. thank you for advice. I assume, that that marks appears in place, where router “goes deeper”. ---

Cutting was pausing only when spindle needs to dive deeper, or in place, where it changes radius (cutting pockets etc.) ---

Yep. That’s a dwell witness. 3d tabs will solve the pair of dwells on the edge/side of tabs Ramps solves the single dwell at the start point of a pockets.
