MKS TMC2209 V2.0 support SENSORLESS_HOMING function

MKS TMC2208 and MKS TMC2225 are used in exactly the same way.The only difference between TMC2225 and TMC2208 is package.The package of TMC2225 is HTSSOP,and the package of TMC2208 is QFN, so TMC2225 have better heat dissipation performance.

  • Driver current regulation
    • Suitable for MKS TMC2209, MKS TMC2225, MKS TMC2208
    • Verf measures the voltage of Gnd and potentiometer middle
    • Please DO NOT connect the motors when measuring the voltage, or it's easy to burn the drive
    • Please connect the power supply when measuring voltage as well, do not connect only the USB power
    • I=Vref Default I=1.25A

Uart mode

  • Since the MKS Robin Nano V1.x motherboard does not reserve the TMC UART interface, so, if you use the TMC UART mode, special processing is required for flying leads. This tutorial on Extended use
