Hi Poli, It sounds like one of the challenges in the membrane filtration step is preventing fouling. Back in the 1970s I worked at a company making zonal separation centrifuges (see attached ad from 1971) and I wonder whether this technique would be helpful. It's a pretty basic mechanism and doesn't rely on any exotic materials or fabrication technology. Even more basic would be batch centrifugby ChuckH - Polymer Working Group
Hi, I am new here and have started working on a RepRap-related project for OSE . The first iteration has been done with grbl on Arduino I have been thinking about converting G-Code to an intermediate PVT (position-velocity-time) waypoint format, then using Arduino to generate the step/direction (using cubic spline interpolation) from that. This is similar to some CANOpen DS402 motion control thaby ChuckH - Controllers
