Notes / Hints

  • The TMC2208 drivers have an improved stealthChop mode (stealthChop2), which works better on higher accelerations. The resistance of the TMC2208 output drivers is also a bit lower, which gives a lower power dissipation.
  • The TMC2130 drivers with SPI have a few more features as the TMC2100, which can be used for motor current setting via software or sensorless homing when the driver is connected via SPI to the mainboard.
  • If the power up/down sequences for 3-5V SilentStepSticks can not be ensured, then we strongly recommend the SilentStepStick Protector.
