Common Debugging Commands

tip

• This tutorial focuses on the Fluidd webpage
• This tutorial assumes that the printer is already properly connected and is used for debugging purposes
• This tutorial provides commonly used commands, but may not be fully comprehensive due to various reasons

Driver Related

Note

• Please note that drivers that are not configured or have issues cannot be checked
• Please ensure all drivers are powered, and that the mainboard power supply, driver jumper settings, and configurations are normal!!

Check Driver Status

• This command verifies the TMC driver status in SPI/UART mode

  DUMP_TMC STEPPER=stepper_x
  DUMP_TMC STEPPER=stepper_x1
  DUMP_TMC STEPPER=stepper_y
  DUMP_TMC STEPPER=stepper_y1
  DUMP_TMC STEPPER=stepper_z
  DUMP_TMC STEPPER=stepper_z1
  DUMP_TMC STEPPER=stepper_z2
  DUMP_TMC STEPPER=stepper_z3
  DUMP_TMC STEPPER=extruder

Force Driver Movement

• Add the following command in printer.cfg

  [force_move]
  enable_force_move: true

• Command to force movement back and forth by 1mm

• Must be executed in the console

  STEPPER_BUZZ STEPPER=stepper_x
  STEPPER_BUZZ STEPPER=stepper_x1
  STEPPER_BUZZ STEPPER=stepper_y
  STEPPER_BUZZ STEPPER=stepper_y1
  STEPPER_BUZZ STEPPER=stepper_z
  STEPPER_BUZZ STEPPER=stepper_z1
  STEPPER_BUZZ STEPPER=stepper_z2
  STEPPER_BUZZ STEPPER=stepper_z3
  STEPPER_BUZZ STEPPER=extruder

• Enable this option to control movement via manual controls

• Please note that only one motor can be moved at a time

• If multiple axes are involved, such as dual Z axes, homing is required before control

  

Force Set Nozzle Position

• Enter the following command in the console to forcibly set the nozzle position. After setting, movement can be directly controlled

  SET_KINEMATIC_POSITION x=100 y=100 z=100

Stepper Motor Step Value Calibration

• First, ensure the extruder is functioning properly, then verify that full_steps_per_rotation and gear_ratio are correct, otherwise extruder step value calibration is not possible

• After obtaining the new rotation_distance, round to three decimal places

• Calibrate step value: rotation_distance = old rotation_distance * actual extrusion length / requested extrusion length

  full_steps_per_rotation: 200        # Steps per revolution (200 for 1.8 degrees, 400 for 0.9 degrees)
  gear_ratio: 50:10                   # Gear ratio (Galileo gear ratio is 7.5:1 and this line should be commented out; BMG is 50:17, output shaft first, input shaft second)
  rotation_distance: 22.522           # Drive pulley circumference in mm

Heating Related

PID

tip

• In the command, TARGET= sets the temperature. Set it to the temperature you normally use for printing
• This command can be used for PID tuning if you have multiple heating devices

• Extruder

  PID_CALIBRATE HEATER=extruder TARGET=245

• Heated Bed

  PID_CALIBRATE HEATER=heater_bed TARGET=100

• PTC

  PID_CALIBRATE HEATER=PTC TARGET=70

Temperature Error Related

tip

• If heating takes too long, refer to this method Click to jump
• If temperature is unstable, use this method to resolve errors caused by unstable temperature Click to jump

Endstop Related

tip

• Updating in progress

Standard Endstops

• Endstop check command
• Ensure the endstop has only two wires. If it has three, verify the wiring sequence to avoid damaging the mainboard!!!
• Ensure the endstop is in the open state and not touching anything
• Enter the following command in the console. If normal, it will return the message below

  QUERY_ENDSTOPS

  
• Ensure all endstops are open, then manually press the endstop and enter QUERY_ENDSTOPS
  
• If the endstop status changes, the wiring is correct

No Endstop

• Please note that the no endstop state must be open, otherwise there is a configuration or wiring issue
• Enter the following command in the console. If normal, it will return the message below

  QUERY_ENDSTOPS

  

Probe Related

BL-TOUCH

• pin_down: Probe extended
• pin_up: Probe retracted
• touch_mode: Sensor verification

BLTOUCH_DEBUG COMMAND=pin_down
BLTOUCH_DEBUG COMMAND=pin_up
BLTOUCH_DEBUG COMMAND=touch_mode

Probe & TAP

• Normally in untriggered state
• It is recommended to add ^ when configuring the pin

QUERY_PROBE

Repeatability Accuracy

• Ten times

  probe_accuracy

• One hundred times

  probe_accuracy samples=100

Special Types

Servo Motors

tip

• Servos are available in 180-degree and 360-degree versions, please distinguish accordingly

• Example configuration

  [servo my_servo]
  pin:PE6

• Example commands

  SET_SERVO SERVO=my_servo ANGLE=360
  SET_SERVO SERVO=my_servo ANGLE=180
  SET_SERVO SERVO=my_servo ANGLE=0
