What is the difference between TMC5160 and TMC2130 SilentStepSticks?
TMC5160 SilentStepSticks have no standalone mode and no internal pull-up resistor on the CS/SS pin. (SPI configuration is always needed)
The direction is not inverted on TMC5160 SilentStepSticks.
The software configuration is mostly the same, except the motor current calculation is different.
TMC5160 SilentStepSticks have an improved stealthChop mode (stealthChop2) and a higher motor current rating.
On TMC5160 SilentStepStick v1.3 the CLK pin has to be connected to GND.
Extra features of TMC2130:
- SPI configuration interface (up to 4MHz)
- up to 256 native microsteps (without interpolation)
- coolStep - current control for energy savings
- stallGuard2 - sensorless motor load detection
- dcStep - load dependent speed control
- Automatic stealthChop and spreadCycle switchover depending on velocity
Note:
This version is not required to be wired. It is used on the F6 board.
