Loading...

Basic Parameters

• Input Voltage: 12V-24V
• Compatible with: Marlin/Klipper/RRF firmware
• Motor is less prone to losing steps
• Supports silent mode
• Large-area fan heat pad reduces driver operating temperature
• Driver mode support: TMC:UART
• Supports motor stall detection

FLY Mainboard Jumper Settings

Tip

• TP2209 uses UART mode
• TP2209 does not require driver jumper caps; only 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:
interpolate: False
run_current: 0.8                    # Running current
sense_resistor: 0.110               # Driver sense resistor, do not change
stealthchop_threshold: 0

Limitless Usage Instructions

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.

Limitless Usage Tips

• The original endstop_pin: needs to be commented out or deleted, then add endstop_pin: tmc2209_stepper_x:virtual_endstop
• After configuring diag_pin:, the limit status will refresh as not triggered
• The configuration for driver_SGTHRS: requires self-testing to find a suitable value
