Quiet Cut Spindle Upgrade for the Shapeoko 2 (#28)

Let's talk spindles: I've been weighing a couple options for awhile now (ex. Dremel 4000, DW660), but Inventables was so keen to show off their own upgrade kit that they put one in my hands and said "Go forth and Make things." So here's a brief overview of my experience with the Quiet Cut Spindle... The upgrade kit consists of the following: [Essentials] 300W Quiet Cut Spindle (https://www.inventables.com/technolog...) 48V Enclosed Power Supply (https://www.inventables.com/technolog...) Motor Speed Controller (https://www.inventables.com/technolog...) Sacrificial Power Cord (https://www.inventables.com/technolog...) Relay Circuit* (https://www.inventables.com/technolog...)
