M303 - PID autotune - Marlin Firmware

m303BÖHLER M303 is a pre-hardened martensitic chromium steel with very hh toughness, wear resistance and machinability. It is suitable for tools processing corrosive moulding compounds, e.g. PVC, and for food and beverage contact.Further pure mathematics (M303) starts once a year – in October. This page describes the module that will start in October 2025. We expect it to start for the last time in October 2029.
