TP 2209

Basic Parameters

• Input Voltage : 12V-24V
• Compatible With : Marlin/Klipper/RRF Firmware
• Motor is less likely to miss steps
• Supports silent mode
• Large fan heat pad, reduces driver operating temperature
• Driver mode supports: TMC: UART
• Supports motor stall detection

FLY Board Jumper

tip

• TP2209 uses UART mode
• TP2209 does not need a driver jumper cap, just simple configuration is needed

TP2209 Reference Configuration

dangerous

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

run_current: 0.8                    # Run current

Unlimited Endstop 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.

Unlimited Endstop Usage Tips

• The original endstop_pin: needs to be masked or deleted, and then add endstop_pin: tmc2209_stepper_x:virtual_endstop
• After configuring diag_pin:, the limit state is not triggered
• Configuring driver_SGTHRS: requires self-testing for an appropriate value
