Re: PID Closed Loop Spindle Speed Control for Quiet Cut Spin

Here are two great resources on a similar project to measure the speed of the DC spindle. They have code in there as well if you'd like to see how they did it.

Re: Best Vacuum for CNC

This is the vacuum that I'm currently using. It works well and isn't quite as loud as other shop vacs I've used. It has a pretty powerful motor rated at up to 5 peak HP with a 5 gallon capacity.
