So I upgraded to a water-cooled spindle — and got the VFD wired up in its new home and configured properly. Here's what I learned. Switching from an air-cooled router to a water-cooled spindle isn't just a power upgrade — it changes how you work. No more manual RPM dial. No more overheating on long jobs. Speed is set through g-code, which means consistent, repeatable cuts every time. This video covers the reasoning behind the switch, how to wire and configure the VFD safely, and what to watch out for — including why the VFD can still kill you after you've turned it off. ⏱️ TIMESTAMPS 0:00 The promise and the problem 0:50 Three reasons I chose a water-cooled spindle 2:35 VFD safety — why it's still dangerous after shutdown 3:38 Enclosure prep and considerations 4:59 Wiring overview 9:30 Initial settings 9:42 Failed first attempt 10:15 Parameter settings and PDF download 11:35 Success!
