    Hi all,
    Currently putting together the Root 3 machine from Thingiverse. I’m planning to control it with a RAMPS1.4 board (designed for 3D printers but more powerful than OpenSource CNC motherboards). Now, I got myself a Moss 710W router for it. It seems to be based on the Makita router.

    So I opened this thing up, pretty standard inners with 1 phase AC motor, smoothing capacitor and thyristor speed control.

    I want to control the spindle speed remotely from my RAMPS1.4 board, which would do so via PWM.

    So how do I control such an AC motor via PWM? Figured someone on here must have experience with this!

    Many thanks :)
