  2. Do not touch the nozzle and heatbed when the printer is working to prevent high-temperature scald and personal injury.
  3. After printing, please take advantage of the residual temperature of the nozzle and clean the filaments on the nozzle with the help of tools. Do not touch the nozzle directly with your hands during cleaning to avoid scald.
  4. Please do product maintenance frequently, and regularly clean the printer body with a dry cloth to wipe away dust and sticky print material under the situation of power off.
  5. 3D printers contain high-speed moving parts, so be careful not to get your hands caught.
  6. Children must be supervised by adults when using the machine to avoid personal injury.
  7. In case of emergency, please cut off the power directly.

Troubleshooting Guide
A stepper motor of the X/Y/Z axis is not moving or making a noise when “zeroed”

  1. The stepper motor cable could be loose. Please recheck the wiring connection.
  2. The corresponding limit switch may not be triggering properly, please check whether there is any interference in the movement of the corresponding shafts and ensure the limit switch wiring is not loose.
  3. Loose timing belt may result in rough motion or abnormal noise in the X/Y axis. It can be resolved by adjusting the tension of the timing belt using the rotary knob.

Nozzle Head Assembly is exhibiting Extrusion Anomalies

  1. Check that the extruder stepper motor cable is not loose or disconnected.
  2. Check whether the set screw of the extruder gear is firmly engaged to the motor shaft.
  3. The heat dissipation of the nozzle assembly may not be enough, verify temperatures and check cooling fan operation.
  4. For clogged nozzles, try first heating the nozzle to 230ºC and pushing the filament by hand to remove a potential clog, or use a fine needle to unclog the nozzle tip while it is heating up.

Model does not Adhere to the Build Platform (PEI Sheet) or is Showing Warping

  1. The key to whether a model can adhere (stick) to the build plate is the largely based on the printing of the first layer. When printing the first layer if the distance from nozzle to platform is more than 0.2mm, it will seriously reduce print adhesion
  2. Try  setting the build model first layer option in Cura to [Brim] to improve first layer adhesion, this should also be used to reduce any cases whereby the edges of the printed model are warping or lifting off the build platform.

Model shows signs of Misaligned Printed Layers

  1. The travel speed of the Printer hot end assembly or Print Speed is set too fast. Please try to reduce the Print Speed
  2. The belts of the X/Y axis may be too loose or the synchronizer pulley is not secured tightly. Check these components.
  3. The current to the Drive may be too low.

Severe Issues in Printed Model of “Stringing” or “Ringing”

  1. Insufficient retraction distance is causing issues, increase the retraction distance in Cura prior to Slicing.
  2. In many cases, if the retraction speed is too slow, you may need to set the retraction speed higher in Cura prior to Slicing.
  3. When slicing your model, check the box for “Z Hop When Retracted” and set the “Z Hop Height” to about 0.25mm.
  4. Print temperature may be too high, which can cause certain filaments to become sticky and stringy.
    If the printing temperature is too high, it can cause the filament to become too fluid and sticky, resulting in poor 3D printing quality.
    In this case, lowering the printing temperature slightly can help.

Supplymentary Introduction

Special Case :
The bottom slide block has been adjusted before leaving the factory, but the pulley of the machine may become loose due to the transportation. If the build platform of the machine is shaky and loose, an open spanner can be used to slowly twist the eccentric isolation column under the platform until the slide block slides smoothly and does not shake.
Similarly, if the print head is shaky or loose, the corresponding eccentric isolation column can also be adjusted until the print head slides smoothly without shaking, and the pulleys on both sides of the gantry also have corresponding eccentric isolation columns that can be adjusted.ELEGOO 3D

Operation Screen Introduction

Auto Leveling

When first running the machine, the distance between the platform and the nozzle needs to be calibrated in the leveling mode, which is about the thickness of a piece of A4 paper.

  • When the printer is powered on, select 【Level】
  • Each axis of the printer automatically returns to the origin. After entering the leveling interface, place a piece of A4 paper between the nozzle and the printing platform, and click the compensation value to adjust the distance between the nozzle and the  printing platform (See picture 2), by pushing and pulling the paper with the friction generated to complete the center point calibration. Then click the auxiliary leveling [ ], and use A4 paper to calibrate the remaining six points of the platform by hand- tightened knobs, and each point can be completed by generating friction on the A4 paper.
  • After completing the auxiliary leveling, enter the automatic leveling for automatic calibration.
  • The machine will enter the heating state:the nozzle is heated to 140°C, the hot bed is 60°C.(Please preset the hot bed temperature according to the temperature of the consumables to achieve a more accurate leveling value.)
  • After reaching the preset temperature: start the 63-point automatic calibration.
  • After the leveling is completed, set the Z-axis compensation: place a piece of A4 paper between the nozzle and the printing platform.
    Click the compensation value and push and pull the A4 paper to complete the compensation and leveling when friction is generated.

Note that the leveling sensor only detects the metal platform plate, for example, replacing the glass platform for leveling will not produce detection effect, which will cause the nozzle to squeeze the platform. ELEGOO 3D

Similarly, you can directly click the automatic leveling [ ]to calibrate the printing platform (See picture 4). After the leveling is completed, set the Z-axis compensation: place a piece of A4 paper between the nozzle and the printing platform, click the  compensation value and push and pull the A4 paper to complete the compensation and leveling when friction is generated. (The front auxiliary leveling is to improve the evenness of the platform and make the compensation effect of automatic leveling better.)

Model Test

Print Head Feeding Check

  1. First push the filaments to the bottom of the print head.
  2. Click 【Prepare】 – 【Extrudert】, click 【Load】, the temperature of the nozzle will be automatically heated to 200°C.
  3. After the nozzle is preheated to 200°C, click the feed to extrude the filamentsfrom the nozzle.
  4. Clean the melted filament of the nozzle before printing.
    NOTE: Filament with different hardness have different requirements for “spring” strength. The spring strength of the extruder can be adjusted with an Allen Wrench(within 2.5mm). When turning counter-clockwise, spring strength is increased, while  spring strength is decreased when turned in a clockwise direction

Start printing

  1. Insert the TF card into the card slot of the printer.
  2. Click【Print】 on the main menu and select the model file.
  3. When the nozzle and the heatbed reach the preset temperature, the X, Y, Z axis will return to zero, and then start printing.
    Notice: When printing the test model, please observe the first layer printing. In cases A and C, the compensation settings are not properly adjusted. Compensation adjustments can be made during printing to adjust the distance between the nozzle and the  platform. In case B, the nozzle and the platform have reached a proper printing distance and can continue printing.

Normal Extrusion State
Rotating the button counter-clockwise:
The extrusion force increases, which means that the filament is pushed out of the nozzle with more force.
Rotating the button clockwise: The extrusion force decreases, resulting in a reduction of the force with which the filament is pushed out of the nozzle.

ELEGOO 3D Neptune Max Printer - Description

When fine-tuning, please switch the moving distance to 0.01mm or 0.1mm to prevent the nozzle from extruding the platform excessively or filament hanging in the air.

Resume Printing Description

Power Loss Recovery:If you want to continue printing because of a sudden power outage or accidentally turn off the power of the machine, this function does not need to be set manually. When the printer is reconnected to the power supply and turned on, just  click resume to continue. (Please note that the PEI platform has a better adhesion effect when it is heated, but it will cool down if the power is turned off for too long, causing the model fall off easily, and the resume printing cannot be completed.)
Filaments Detection:This function is to remind the user to replace the filaments before continuing printing when the model is half-printed, which effectively prevents the model from being scrapped due to insufficient consumables.
