Spent a lot of time researching stuff about cnc desktop mills and bought a Sable 2015. all seems to be going well with the learning curve ( only ever used a lathe in the past, not CNC). Only reald problem I had was with the EMF noise from the spindle motor butt I have that issue solved. Now I'm working on the spindle to get some control. I have built a manual speed controller that can be switched on and off via Mach 3 by using a speed controller from an old broken router and an SSR I had laying around, That's about the limit of my abilities as far as AC circuits go. Anyone got any ideas on PWM control? I know I can buy something suitable but I am an infernal fiddler. Too much time and an understanding wife ( or she's happiest when I'm in the shed?)

A more basic question. As CNC is new to me, Now I have a small mill and a large hammer, what other essential parts/ accessories do you think I need?)
