Hardware Installation and Configuration​

Motherboard Jumper Settings​

The TMC5160 Pro uses SPI jumper mode:

  • The SPI pin for FLY drivers is the 4th pin from the top left (CS pin)
  • If using other motherboards, please confirm pin compatibility

Firmware Configuration​

Important Note
  • Sense resistor value: sense_resistor: 0.033 (Do not set incorrectly)
  • Choose only one configuration between spi_bus and spi_software

SPI Mode Configuration Example​

[tmc5160 stepper_x]
cs_pin:                    # SPI chip select pin
spi_bus:                   # SPI bus (choose one between this and spi_software_*)
# spi_software_mosi_pin:   # Software SPI data output
# spi_software_miso_pin:   # Software SPI data input
# spi_software_sclk_pin:   # Software SPI clock
run_current: 1.0           # Run current setting
interpolate: False         # 256 microstep interpolation (True to enable/False to disable)
sense_resistor: 0.033      # Sense resistor value
stealthchop_threshold: 0   # Silent mode speed threshold
driver_DISS2G: 1
driver_DISS2VS: 1

Sensorless Homing Configuration​

Infinite Position Usage Tips
  • Using infinite position requires occupying one limit port. Normally, the first drive uses IO1, the second drive uses IO2, and so on.
  • When using infinite position, please ensure that nothing is connected to the corresponding limit port.
  • Some FLY mainboards have directly connected drive ports. Please check whether DIAG is directly connected to the corresponding pin.
Usage Instructions
  1. Hardware Preparation: The 4-pin FPC cable must be installed.
  2. Configuration Modification:
    • Comment out or delete the original endstop_pin:.
    • Add endstop_pin: tmc5160_stepper_x:virtual_endstop.
  3. Status Confirmation: After configuration, the endstop status should show "not triggered".
  4. Sensitivity Adjustment: The driver_SGT: value needs to be adjusted based on actual conditions.

Reference Configuration​

[stepper_x]
# endstop_pin:                 # Comment out or delete original configuration
endstop_pin: tmc5160_stepper_x:virtual_endstop
homing_retract_dist: 0        # Set to 0 to avoid homing failure due to retraction

[tmc5160 stepper_x]
diag0_pin: ^!                  # Usually requires a pull-up resistor
driver_SGT: 1                  # Sensitivity value (adjust based on actual conditions)
Configuration Suggestions
  • diag0_pin: typically uses the ^ prefix to enable internal pull-up.
  • Sensitivity is affected by factors like belt tension and mechanical structure; the optimal value needs to be determined through testing.
  • The driver_SGTHRS parameter can also be set to adjust the sensitivity threshold.
