All fair points. I havent seen much about it. My only thought was that with my MPCNC I have to go pretty slow because the z axis is not as rigid as just holding the router right by the work piece. Pockets that take 10 minutes to cut out on my mpcnc take 2 to just hog out with the router by hand. But I am using old parts, a tall z axis, and some cracked parts that I couldn’t print replacements for over the summer.
