So many critical comments, with albeit legitimate critiques, that are missing the point. This is an open source hobby project that is designed to be built with a 3d printer and a few inexpensive off the shelf parts. I have yet to see another rotary table based cnc project like this. does it have some inherent design compromises and short comings? yes, but this is a starting point. The initial reprap project was (an ancestor of this project, no doubt) was also very flawed. This is the starting point of a pretty novel take on desktop cnc and if it gains some traction, will also evolve and iteratively improve.
- SeasonalEnnui 5y agoI think we simply rejected the point. There are many newcomers thinking they can disrupt the space with terrible designs. Open source shouldn't mean terrible design. There are many better open source CNC already.
- jjoonathan 5y agoMachining without rigidity is a Hard Problem. If someone expects to just iterate past it or trade away a bit of performance and ignore it, they are in for serious disappointment. This isn't necessarily obvious to people without CNC experience: just look at the number of people in this thread who think deflection compensation can solve rigidity problems. There's no shame in being new to CNC and not really understanding or believing the hype about rigidity, but the Polar Bear company has a financial interest in pushing people towards learning these lessons in an expensive & time consuming manner. That's exactly what they're doing. The people with CNC experience have seen this show before, have seen the burned customers, and are just trying to make sure that expectations stay in the ballpark of reality.
