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.
Wiring Detail

- If smart controller is on Aux 3 - need to wire into Aux 2 headers - see Step 4 at [1]. 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?
