Bowl and Tray bit doesn't render correctly in simulation
I have a SpeTool Bowl and Tray bit that is included in the SpeTool tool spec download for Carveco Maker. But it doesn't render correctly when doing a simulation - it doesn't show the rounded bottom. I've tried googling the problem, and I saw someone with the same problem on an Infinity forum from 2024, but it had no responses, and I can't find anything else relevant. It's set up in teh database like this screenshot. I've also tried a different SpeTool bowl bit and it does the same thing. It has sharp corners at the bottom.
This is how it renders in the simulation -
Anyone have any idea what the problem might be?

Hi Rich,
The problem is at the tool's settings. As you can see in your screenshot, the shape next to 'Notes', it seems to be flat. I tried to create a similar tool (check image below). The Arc radius should not be less than 0.375 (half of D at least) in order to get the rounded shape you need. Also, the inner diameter should be 0.
I am not a tool/toolpath/g-code expert... but I think that should solve your issue. Give it a try!

Thanks for responding Elina. I don't know what 'd' (inner diameter) refers to (maybe the shaft diameter?), but 'R' I believe is correct at .25". The bit has a flat bottom and rounded edges. The radius of the rounded part is .25".
Now that I think about it, maybe inner diameter (d) is the flat bit - which would also be 0.25". I'll try that next time I'm on my laptop.
This does appear to be it. Inner Diameter (d) is the flat bit, which has a diameter of 0.25". This seems to render correctly. Hopefully it machines correctly too (don't see why it wouldn't).
Hi Rich,
Not sure if I helped, but I'm glad you worked it out! Hope you get the desired results :)
Indeed Elina, your response was inspirational. 😀
Thanks.
Experimenting usually works.. Glad I helped! 😊
