This is exactly the point we were trying to make on getting some Thumbs Up on this post to have OneFinity make an adapter plate for the Z-Axis to support actual Mulling Motors.
Trim routers like the Makita and every other brand on the market are not designed to run for hours upon hours of time. They are for trimming cabinets, or jobs that typically take <30min at a time. They do work for CNC machines (clearly as a ton of them across many brands are being used.) That does not however mitigate the fact that it is not what they are intended to do. In fact the second you put one on a CNC you void the Makita warranty.
