I have already built and assembled the electronics for a new line of ALMAZ-CNC engraving machines: an STM32-based control board driving a TI DRV8323RS three-phase stage and reading rotor position from an AS5047P magnetic encoder over SPI. What I still need is production-ready firmware—and that is where your expertise comes in. The goal is a closed-loop, Field-Oriented Control implementation that can deliver both precise positioning and very fast bidirectional swings in the 200–300 Hz range. Because the machine relies on high-frequency oscillating motion to achieve clean, chatter-free cuts, every millisecond of latency or overshoot matters. You will be writing C/C++ code for the STM32, bringing up the FOC algorithm, integrating the SPI encoder feedback, and then tuning current,...
