Wire Via SPI for Stealth Mode

  • Solder certain bridges on the driver - not easy
  • Change Marlin code in configuration_adv.h
  • Need to change pins_RAMPS.h file to tell which pins are being used
  • Debug allows M122 in serial monitor for status
  • Define sensorless_homing in config_adv !!! This is useful.
  • Disable endstops_pullup for sensorless homing
  • M914 in sensorless homing determines sensitivity of sensorless homing
  • Need to upgrade to Marlin 1.1.9 from 1.1.0 to do sensorless homing.

Analysis of Torque

  • According to test results at 36V - the torque is great in Stealth Mode up to to 250mm/s - [1]

Wiring Detail

Source 1

  • If smart controller is on Aux 3 - need to wire into Aux 2 headers - see Step 4 at [2]. Disclaimer - author questions validity of LCD working with TMC2130
  • Covers 3 parameters set in software - sensitity to bump stop; holding torque; conversion from 16 to 256 microsteps
  • Stealth chop gets you less power - how much less? Less speed. Unacceptable for fast bulk prints on large printers
  • Can run in hybrid mode to set Stealth mode only below a certain speed, and high speed is noisy.
  • Nothing about solder bridge on the driver to select mode?

Links

  • Marlin docs on TMC2130 - [3]
  • Hackaday post - summary is that it's a job to configure properly - [4]
  • Prusa forum - good list of references - and explanation of low torque is 12v operation instead of 24 or higher. 1A at 24V only is required to run all stepper motors??? [5]. See first response, Hardware point #9.
