A guide to sensorless homing for RP2040 microcontrollers, showing no limit switches are needed with these components.
By Lewis February 24, 2026
In this video, I’ll show you how to set up sensorless homing using a TMC2209 stepper driver — no mechanical limit switches required! Perfect for 3D printers, CNC machines, robotics, and other DIY electronics projects. I’ll guide you through the wiring, Arduino code, and how to tune StallGuard for accurate, reliable homing. Whether you’re building a CoreXY, a custom motion control system, or just want to learn more about stepper motor drivers, this is a great place to start. Let’s build smarter! Why would we want to use sensorless homing? Well first the Pros…. There’s no need for extra mounts, additional components or running long dangling cables to one or both ends of the carriage or other moving component. And there are always cons, so in this case you’ll need a stallguard-capable driver (they cost a little more and are only manufactured by Trinamic) and accuracy isn’t great at slow speeds.
