Brushless Battery powered dewalt router on Maslow 4?

Hardware
1

One of the biggest complaints newbies have with CNC machines powered by the dewalt palm routers is the brushes wear out and need to be replaced. When one is using the router by hand the motor starts not running smoothly and an experienced wood worker can hear the brushes are about done. However, when left on a cnc it is harder to tell. Newbies often put the speed at fastest and this makes the brushes wear out faster.

So why not use a brushless router? Well because the only ones that are brusheless are the battery powered ones and it would suck to have the cut stop in the middle of a job. One can make an AC power adapter like this:
Cordless Power Tool Conversion 18VDC to 120/240VAC : 10 Steps (with Pictures) - Instructables

I also noticed the speeds for the battery powered dewalt are a bit fast?
DIAL RPM
1… 16000 rpm
2… 17500
3 …19100
4 …20700
5 …22300
6 …23900
7 …25500

The makita battery powered router goes slower 10K to 30K RPM and costs less.but one will need a 2mm thick shim to make it fit the Maslow4

Also got the issue that the control board fits on top of the router (is physically attached) so can’t just be easily removed to do a battery swap. There is also some reasoning that the rotor fan provides some cooling to the control board which wouldn’t occur with the battery or adapter in the way.

those are minor issues easily solved with velcro or some 3d printed holder IMHO.

That wouldn’t fix the cooling air flow issue ??

I believe, correct me if wrong, Bar said somewhere that he had added a cooling fan and it wasn’t as dependent on the router for cooling anymore.

yes the board has an internal colling fan.
