TP 2209

Basic Parameters​

  • Input Voltage: 12V-24V
  • Suitable for: Marlin/Klipper/RRF Firmware
  • Motor does not easily lose steps
  • Supports Silent Mode
  • Large heat pad for fan, reduces drive operating temperature
  • Drive mode support: TMC: UART
  • Supports motor stall detection

FLY Mainboard Jumper Settings​

tip
  • TP2209 uses UART mode
  • TP2209 does not require drive jumper caps, only simple configuration is needed

TP2209 Reference Configuration​

dangerous

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               # Do not change the drive sampling resistor
stealthchop_threshold: 0

Infinite Limit Usage Instructions​

Infinite Position Usage Tip
  • Infinite position usage requires occupying a limit port, normally IO1 is used for the first drive position, IO2 for the second drive position, and so on.
  • When using infinite position, please make sure not to connect anything to the corresponding limit port.
  • For some FLY motherboards, the drive ports are directly connected, please pay attention to whether DIAG is directly connected to the corresponding pin.
Infinite Limit Usage Hint
  • The original endstop_pin: needs to be disabled or deleted, and add endstop_pin: tmc2209_stepper_x:virtual_endstop
  • After configuring diag_pin:, the limit status refresh is not triggered
  • Configure driver_SGTHRS: needs to test a suitable value on your own
  • Reference Configuration
