TP 2209

Loading...

Basic Parameters

• Input Voltage: 12V-24V
• Applicable Firmware: Marlin/Klipper/RRF
• Motor less prone to losing steps
• Supports silent mode
• Large area fan thermal pad, reducing driver operating temperature
• Drive mode support: TMC:UART
• Supports motor stall detection

FLY Motherboard Jumper Settings

Tip

• TP2209 uses UART mode
• No driver jumper caps required for TP2209; only simple configuration is needed

TP2209 Reference Configuration

Danger

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

[tmc2209 stepper_x]
uart_pin:

run_current: 0.8                    # Running current
sense_resistor: 0.110               # Do not change the driver sense resistor

Instructions for Using Without Endstop

Infinite Position Usage Tips

• Using infinite position requires occupying one limit port. Under normal circumstances, the first drive position uses IO1, the second drive position uses IO2, and so on.
• When using infinite position, please note: do not connect anything to the corresponding limit port.
• Some FLY motherboards are directly connected to the drive port. Please check whether DIAG is directly connected to the corresponding pin.

Tips for Using Without Endstop

• The original endstop_pin: needs to be commented out or deleted, then add endstop_pin: tmc2209_stepper_x:virtual_endstop
• After configuring diag_pin:, refreshing the endstop status will show as not triggered
• Configuring driver_SGTHRS: requires testing for a suitable value
