I have a first-generation Maslow (without the ring). I’d classify it more as an ongoing group project than functional tool right now. The accuracy was pretty bad for me even after a few rounds of calibration. They (Maslow and the community) are very active in improving the Maslow and are trying to address the biggest issue with the router basically being a pendulum between the two fixed points on the sled that the chain attaches to. There are several solutions to this being tested that make the chains behave as if they terminated exactly at the router bit, reducing computing and error. this requires either linkage systems on the sled, rings and rollers, or other complications to the system.
It’s a pretty fascinating project, however, and there are several very smart people in the community working on it, but it’s never been a fully functional tool I could just use. I didn’t have time to test out the ideas that were thrown around, and it never really addressed the fundamental problem for me: it’s a sled that rides on your workpiece. If you want to cut near the edge or a milled pocket, the sled might tilt. 3d carving is basically out of the question. Little bits that get kicked up interfere with the sled. Etc etc.
Was drawn to the mpcnc and lowrider initially thinking I’d just make a floating XY frame out of the components for my Maslow for it to hover above the work, but then thought better of it and am going to try out a modified low rider to replace my Maslow. I don’t want my cutter riding on the worksurface - because then I can surface plane, carve, and use small bits of scrap easily instead of full sheets of plywood.
I still have an idea for the Maslow: using the geared motors for a power-tilting table for the lowrider. We’ll see…
