If your CNC machine has ever done something so weird you just stood there staring at it… this episode is for you.

Garrett and Liberty are joined by Alex Duffey from @DuffeyWoodcraft for a conversation focused on one of the most important parts of CNC success…

We’re joined by Alex Duffy of Duffy Woodcraft, who shares his experience with Next Wave machines, production work, craft fairs, and the kinds of strange machine behavior that most CNC users eventually run into. We also talk about spindle power, bit choice, O-flute bits for plastics, why previewing toolpaths matters, and how small setup mistakes can create big headaches.

If you’re a beginner trying to understand why your CNC keeps doing odd things, or an experienced user who wants to tighten up your process, this episode will help you troubleshoot smarter and work with more confidence.
