I have the router controller. It let’s you dial down the free speed, but it does not control the speed. When you start cutting, it will slow down. Probably not measurably in foam.
Something like the super pid monitors the speed and adjusts the current to keep it steady. The 611(lowrider) and makita also do this. Imo, it’s a game changer. I also did nicely for kind of a long time on the 660 with just the router speed controller.
If you have a good ear for pitch and most of your cuts are similar loads(adaptive/trochoidal is good for that), you can set the speed and measure with a cheap optical doodad, then adjust on the fly once it starts cutting and be good’nuff.
Definitely worth it imo, especially for foam unless your just BLAZING through it and need the speed. That thing really quiets down in a hurry when you start turning the knob.
that makes sense. With foam there won’t be as much resistance as wood. When I do wood I can dial it up.
The main purpose for my router is to carve RC plans out of construction foam and will really be the only material I cut. There will be some wood, but only 1/4" for wing spars. So I could find the sweet spot and mark it with a marker.
