RE: [CAD_CAM_EDM_DRO] SPINDLE speed controller, collets, WAS re: Roland CAMM-3 ?

Hi Les,

A simple light dimmer? That's surprising. Surely there's more to it then
DC damaging the switch!

There is a Kress router with a variable speed, but I couldn't get
Techno-Isel to quote me on it. Probably can't afford it anyway!

For starters, I'll probably be happy running it at 30K.
