Notes / Hints

  • The TMC22xx and TMC516x drivers have an improved stealthChop mode (stealthChop2), which works better on higher accelerations.
  • The resistance of the TMC22xx output drivers (RDSon) are a bit lower compared to the TMC21xx, which gives a lower power dissipation.
  • The TMC2209 drivers with UART interface have a few more features, which can be used for motor current setting via software or sensorless homing when the driver is connected via UART to the mainboard.
  • The TMC2130 and TMC516x drivers with SPI interface have a few more features, 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 SilentStepSticks with variable logic voltage (3-5V) can not be ensured, then we strongly recommend the SilentStepStick Protector.

  1. no standalone mode ↩︎

  2. without interpolation (microPlyer) ↩︎

  3. maximum motor phase current only possible with a heat sink and active cooling (no heat sink for TMC5160) ↩︎

  4. Motor Supply Voltage (VM) is always needed, when the internal voltage regulator is enabled/used ↩︎
