Notes / Hints

  • The stealthChop operating mode is nearly silent.
  • The TMC22xx and TMC516x drivers have an improved stealthChop mode (stealthChop2), which works better on higher accelerations.
  • The resistance of the TMC22xx output drivers are a bit lower compared to the TMC21xx, which gives a lower power dissipation.
  • The TMC2130 and TMC516x drivers with SPI 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. without interpolation (microPlyer) [return]
  2. maximum motor phase current only possible with a heat sink and active cooling [return]
  3. Motor Supply Voltage (VM) is always needed, when the internal voltage regulator is enabled/used [return]
