All machines that are driven by belts - are complete fail when we would try to do small and precise work.
there are only two working solutions: ballscrew and magnetic guide. See the price of the magrails - there is only one left)

Cutting more Aluminum on my MPCNC

A solid success cutting aluminum on the MPCNC, with a 17"x13" volume. I included the feeds, speeds and settings below (and in the video): [Milling an Aluminum Plate on my MPCNC] This isn’t a stock MPCNC though. If you want to see the upgrades I made to it, see this video: [Boss-level upgrades to my CNC machine #mpcnc #hackaday] Cut settings: Bore holes: 1.9mm single-flute carbide 34,000 RPM Feed rate: 300 mm/min Ramp angle: 2 deg Contour/Profile cuts: 3.175m…

Thats one of the examples and with a way less rigid machine than the lr4.
It all depends on how well you build yours and how well you dial in your cutting settings
