Hey NewsVan,
the other day I wrote this, with links on comparison regarding choice decision between buildbotics-derived Onefinity Controller on Original/PRO Series and MASSO G3 Touch on Elite Series, specifically
Note that you may also use some CNC Controllers other than Onefinity offers. The original Buildbotics CNC Controller from buildbotics.com should work out of the box (posting which describes the differences). Here in the forum they also use the Centroid Acorn, like shown here and here.
I think people who switched to a spindle would never go back. It’s also a matter of safety. You can’t say that a hand trim router used outside of its scope is a reliable CNC milling motor. And it’s a matter of effectivity. A hand trim router produces much less mechanical power for the electric current drawn than a spindle, because of its poor efficiency, and it emits noise and electromagnetic interference through its carbon brush commutators (a spindle has no such). But it depends on what you want to do. If you only make name signs for thanksgiving table once a year, possibly you don’t miss a spindle
