TMC Error Related

  • Unable to read tmc uart ‘stepper_x’ register IFCNT or Unable to read tmc spi ‘stepper_x’ register register

    1. Error Details

      Loading...

    2. Error Cause

      • Unable to communicate with the driver.

    3. Main Solutions

      • Check if the UART pin configuration for the corresponding driver is correct.
      • Check if the UART jumper is correct.
      • Check if power is supplied to the driver.
      • Replace the driver or change the driver port configuration for diagnosis.
      • If using a driver from another manufacturer, you need to determine if its UART pin is consistent with FLY's. The UART pin for FLY drivers is the fourth pin from the top on the left side.

      • If the UART pin of the driver you purchased is on the fifth pin, you can resolve it by using the jumper method shown below.

    2. Error Cause

      • Driver reset.

    3. Main Solutions

      • Poor contact in power wiring.
      • Motor wire break.
      • Connect the metal casing of the motor to the GND of the mainboard or toolboard.


  • TMC 'extruder' reports error: DRV_STATUS: c00d0103 otpw=1(OvertempWarning!)

    1. Error Details

    2. Error Cause

      • Driver overheating!
      • Not motor overheating!

    3. Main Solutions

      • Reduce operating current.
      • Remove holding current.
      • Check if the driver's sense resistor is correct.
      • Improve driver cooling, e.g., add a fan.


  • TMC ‘extruder’ reports error: DRV_STATUS: 601f1000 s2vsa=1(ShortToSupply_A!) csactual=31 ola=1(OpenLoad_A!) olb=1(OpenLoad_B!))

    1. Error Details

      • No image available.

    2. Error Cause

      • Incorrect driver current detected.

    3. Main Solutions

      • Check if the resistance of the two coil groups (A and B) of the stepper motor is consistent.
      • Check for loose or shorted wires inside the stepper motor or component motor.
      • Disable stealthChop mode.


  • TMC 'extruder' reports error: DRV_STATUS: 00190060 s2vsb=1(ShortToSupply_B!) ola=1(0penLoad_A!) cs_actual-25

  1. Main Solutions

    • Check if the resistance of the two coil groups (A and B) of the stepper motor is consistent.
    • Check your stepper motor and wiring.
    • Check the motor wire sequence to ensure the left side is one group and the right side is another group.
