The advantage of this mod is that it’s essentially free vs $150+ for SuperPID.
If I decide to spend money on an upgrade it will be for a real spindle with a VFD.
I would certainly go for a spindle when possible. A spindle upgrade is easily more than $150, the mount has to be changed out, and things need to be realigned.
For some, that is a lot of bear and SuperPID is a very viable option to gain flexibility… especially the lower RPM range.
I can’t say how well the Dewalt or any other router holds it RPM well under load. Closed loop should do a good job. SuperPID provides a close loop for all routers.
