Verify Stepper Motors

This section explains how to use the STEPPER_BUZZ command to verify the connectivity of each stepper motor. Start by manually positioning the given axis to a midway point. The STEPPER_BUZZ command will cause the given stepper to move one millimeter in a positive direction and then it will return to its starting position. If the Endstop is defined at position_endstop=0 then at the start of each movement the stepper will move away from the endstop. It will perform this oscillation ten times.

• Testing the X Stepper Motor;

  • With the Hot End/Extruder physically located in the centre of the printer;

    • Send a STEPPER_BUZZ STEPPER=stepper_x command in the Console;

X Stepper Motor

• Looking at the Hot End/Extruder, you should see it shift left and right 1mm, 10 times;

• Testing the Y Stepper Motor;

  • With the Heater Bed physically located in the centre of the printer;

    • Send a STEPPER_BUZZ STEPPER=stepper_y command in the Console;

Y Stepper Motor

• Looking at the Heater Bed, you should see it shift forward and back 1mm, 10 times;

• Testing the Z Stepper Motor;

  • With the Hot End/Extruder physically located in the centre of the printer;

    • Send a STEPPER_BUZZ STEPPER=stepper_z command in the Console;

      • The movement is only 1mm, but make sure you have enough clearance between the Hot End/Extruder and the Heater Bed before running this command;

Z Stepper Motor

• Looking at the Hot End/Extruder, you should see it shift up and down 1mm, 10 times;

  • You may notice that only one of the Z Stepper Motors will move, this is normal behaviour.
