Just a small discrepency betwwen text and linked source. https://ellis3dp.com/Print-Tuning-Guide/articles/determining_motor_currents.html **Different stepper drivers have different maximum currents.** - For example TMC2209 drivers are rated to **2a RMS**, but I would generally not exceed 1.4a RMS. Looking at the [provided link](https://learn.watterott.com/silentstepstick/comparison/), the TMC2209 drivers are actually rated for **1.7A RMS**.
