A couple of years ago I purchased a Bosch 1617 EVS router for use with my CNC machine. In general it works well but one thing that I wanted that it didn’t have was a way to better control the router RPM’s. Then I learned about a device called the SuperPID Speed Controller which retrofits a router to permit better spindle speed control, and it has the added advantage that it can integrate with the Mach3 CNC controller software.
Upgrading the router is not terribly difficult but it isn’t totally easy either. So as I was modifying my router I took lots of pictures of the process, partly to help myself remember what I did, but also to help someone else if they’re thinking about the SuperPID speed controller and have a similar router.
Here is a link to the build log.
Sorry there’s no descriptive text but I think you’ll find the pictures helpful enough on their own. One of the trickiest parts of getting it back together though was figuring out a way to hold the commutator brushes out of the way while I slipped the outer housing back on. I used a couple of pencils and rubber bands for this. When you get to that step, you’ll understand what I mean.
