TP 2209

Basic Parameters​

  • Input voltage: 12V-24V
  • Suitable for: Marlin/Klipper/RRF firmware
  • The motor is not prone to losing steps
  • Supports silent mode
  • Large area fan thermal pad to reduce drive operating temperature
  • Drive mode support: TMC: UART
  • Supports motor stall detection

FLY Motherboard Jumper​

tip
  • TP2209 uses UART mode
  • TP2209 does not require driver jumper caps, just pure configuration is needed

TP2209 Reference Configuration​

dangerous

The drive sampling resistor is 0.110, please do not set it incorrectly

[tmc2209 stepper_x]
uart_pin: 
interpolate: False
run_current: 0.8                    # Motor running current value (unit: mA)
sense_resistor: 0.110               # Drive sampling resistor do not change
stealthchop_threshold: 0

Infinite Position Usage Instructions​

Infinite Position Usage Tips
  • Infinite position usage requires occupying a limit port; normally, the first drive position uses IO1, the second drive position uses IO2, and so on.
  • When using infinite positions, please ensure not to connect anything to the corresponding limit port.
  • For some FLY mainboards that are directly connected to the drive port, please check if DIAG is directly connected to the corresponding pin.
Infinite Position Usage Tips
  • The original endstop_pin: needs to be shielded or deleted, and add endstop_pin: tmc2209_stepper_x:virtual_endstop
  • After configuring diag_pin:, refreshing the limit status is not triggered
  • Configuring driver_SGTHRS: requires you to test a suitable value by yourself
