Calibration can help you achieve excellent print results, so read this section carefully, or you may cause printer damage and print failure.Prepare a standard piece of A4 paper and lay the printer flat The ER-20 3D printer firmware turns on the automatic leveling function by default. The sensor Eryone developed enables the machine to automatically level. We can Level the printer easily by calibrating.Auto leveling❶ Preparation Home the printer to default location. ❷ Auto Home Click the LCD and click “Configuration” to enter“Calibrate Z” menu then level the printer according to the instructions.❸ Calibrate Z axis.

□ Bed: Heated bed temperature parameters setting.□ Fan speed: Fan speed control.□ Nozzle: Nozzle temperature parameter setting.Nozzle cooling fan speed setting, using PWM to adjust fan speed, the parameters are 0~255, corresponding to running at a rate percentage of 0~100%.Generally do not let its speed below 20%, otherwise situation that fans can not work properly might appear.□ Preheat PLA: Preheat menu. Preheat the nozzle, heated bed, or both. When using this feature, the heating component will enter the heating state according to the PLA preheating parameters preset in the firmware.■ Motion:Printer motion parts control menu to move every axis.Motion Menu ■ Temperature: Menu for nozzle temperature, heated bed temperature and cooling fan speed□ Move axis: Move each axis □ Move X: 3 type of mode,10mm/1mm/0.1mm □ Move X: 3 type of mode,10mm/1mm/0.1mm □ Move Z: 4 type of mode,10mm/1mm/0.1mm/0.025mm □ Move E: Extruder extrusion filament (need Preheat first), 3 type of mode,10mm/1mm/0.1mm □ Auto home: Auto home all three axes of the printer XYZ □ Level Bed: Using this feature to auto level the printer（The offset point needs to be set first, This will be explained on the Probe Z Offset menu) □ Fade Height: Fade the amount of Mesh Based Compensation over a specified height. At the specified height, no correction is applied and natural printer kinematics take over. If no number is specified for the command, 10mm is assumed to be reasonable.□ Disable the Stepper: After the stepper motor is disabled, the motor self-lock function is unlocked and the stepping motor can be moved manually□ Bed leveling: Enable the auto bed leveling or not(Default enable)12

□ Preheat ABS: Preheat menu. Preheat the nozzle, heated bed, or both. When using this feature, the heating component will enter the heating state according to the ABS preheating parameters preset in the firmware.□ Advanced Settings:Advanced parameter setting menu □ Set Home offsets: Sets the current printer's coordinate value as the home offsets□ Velocity:Printer speed parameter control menu□ Acceleration: Acceleration control menu□ Jerk:Accelerating arc parameter setting■ Configuration:This menu is the most complicated part of the LCD menu.

Advanced Settings includes advanced parameter setting, autoleveling sensor parameter setting, etc□ Vmax X: X-axis movement speed upper limit□ Vmax Y: Z-axis movement speed upper limit□ Vmax Z: Z-axis movement speed upper limit□ Vmax E: Upper limit of the rotation speed of the extruder□ Vmax Min: Maximum value of Printer moving speed □ Vtrav Min E: Minimum value of Printer deadhead moving speed□ Accel: The overall acceleration value of the printer □ A-Retract: Printer extruder motor retract acceleration setting□ A-Travel: Printer travel acceleration maximum value setting□ A max X:X axis moving acceleration maximum value setting□ A max Y: Y axis moving acceleration maximum value setting□ A max Z: Z axis moving acceleration maximum value setting□ A max E: Extruder acceleration maximum value setting13

□ Probe offsets: Auto Leveling sensor offset setting□ Steps/mm: Number of steps of motor rotation per millimeter printer moves□ TMC Drivers:stepper motor driver setting□ Probe X offs:Auto Leveling sensor X axis offset setting□ Probe Y offs:Auto Leveling sensor Y axis offset setting□ Probe Z offs:Auto Leveling sensor Z axis offset setting □ X Steps/mm: Number of steps of motor rotation per millimeter printer X axis moves. The parameter is related to the type of motor, the numberof teeth and the pitch of the synchronous wheel The parameter is related to the type of motor, the number of teeth and the pitch of the synchronous wheel □ Y steps/mm: Number of steps of motor rotation per millimeter printer Y axis moves□ Z steps/mm: Number of steps of motor rotation per millimeter printer Z axis moves. The parameter is related to motor type and Z-axis screw type□ E steps/mm: Number of steps of motor rotation per millimeter printerextruder rotates, the parameter is related to motor type and feeder gear type□ X Steps/mm:TMC drivers current setting □ Stepping Mode: Switch the working mode of the stepper motor driver, on means silent mode on, off means silent mode off□ Sensorless Homing: Infinite Limit switch function Settings, mainly to adjust the X/Y axis of the stepper motor driver sensitivity. The sensitivity of the driver to the resistance when the XY axis moving and homing.It should be noted that too high the value is likely to lead to higher sensitivity value, resulting in failure of the homing.14

□ Temperature: This option is related to the automatic temperature adjustment function setting □ Temperature: Filament setting□ Initialize EEPROM: Initializes the EEPROM data□ Autotemp: Whether to turn on automatic temperature adjustment (off by default) □ Min: Minimum value of automatic temperature adjustment □ Max:Maximum value of automatic temperature adjustment □ Fact: Automatic temperature adjustment temperature coefficient（related to firmware）□ E in mm3: This function is used to measure the consumption of filaments. Whether mm3 is used as the unit or not, off by default. □ Probe Z offset:□ Unload mm:Extruder unload length □ Load mm : Extruder load length Auto leveling sensor key parameter。Adjusting this parameter can change the offset height of the sensor，Offset point refers to the height between the nozzle and the hot bed by moving the Z-axis to 0 after the printer is returned to its position with the automatic leveling sensor. □ Calibrate Z： Auto leveling sensor calibration menu. Entering this menu can quickly adjust the offset height of the sensor without using other menus for homing and other operations. □ Bltouch: Ery sensor control menu. Enter this menu to check whether the function of the sensor is normal. □ Outage Recovery: Power resume print menu. You can turn it on or off.On by default .□ Preheat PLA conf: Preheating parameter configuration menu for printer PLA. On this menu you can adjust the heating temperature values of the nozzle and the heated bed. 15
