Hi all, as the title suggests really. I don't often use Fusion for CAM so I've not had to deal with this issue, but I have job coming up and it needs addressing.

I noticed the issue recently when cutting an adaptive pocket, it basically spirals out from the centre. The curves are a really jerky movement and I had to stop it.
I don't have the same issues when using Aspire.

Here's the processed code (deleted the majority in order to meet character limit)..

Code: Select all

Any help appreciated.

Loosen up your CV tolerance settings.

Hi Gerry, is this done in UCCNC? I haven't ever changed it so what would be a good amount to change by?

Thanks
