Hi I'm Peter and a member since March 23. I have a Computer Science background and do Digital stuff from Silicon atom up to the cloud since over 4 decades. As my job is my hobby and vice versa, I deal with embedded systems, currently on STM32 line. I also like to work on mechanical things, especially with metal. To brush up my old knowledge in lathing, I had two training courses in 2022 at the "Haus der Eigenarbeit/Ostbahnhof" on a big Weiler lathe. I have built the MAXYposi CNC belt driven mill as presented in Make magazine. After improving the mechanics I found out that the resolution of the steppers with microstepping is insufficient, so I am now developping a closed loop controller, using magnetic 21bit encoders, based on the SimpleFOC software, see https://www.simplefoc.com/
