I am so amazed at the difference a lead screw driven machine (The OpenBuilds Sphinx) has made vs. my belt driven (OpenBuilds OX) machine. I can actually set some pretty aggressive cut settings for the feed rates and depth of cut. I figure I have increased things by a factor of at least 4.
did you convert your belt machine or got a new one?
Last I checked, Brandon still had a used R7 in his set of stuff he is selling off…
Yeah, still listed for $1K, minus controller, at:
I built a new one. Sold the OX to pay for the Sphinx.
