Cautions

1. Do not place the printer in vibrating or other unstable environments, as the shaking of the machine will affect the print quality.
2. Do not touch the nozzle and heat it 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.

Packing List

Machine Installation

Attached U disk with an installation instruction video. Print head installation: Use 3pcs (PM3*14) screws to fix the print head through the holes of the metal plate from the rear 2pcs (PMM3*8) screws to fix the front of the print head.

Supplementary 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 this 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.

Operation Screen Introduction

Auxiliary cooling module instructions:
Users can click the fan icon to adjust the air outlet status of the rear cooling fan during the printing process. The fan has three modes: silent/normal / sport, please adjust according to the printing situation, as shown in the picture below.

Model Test

Print Head Feeding Check

1. First, push the filaments to the bottom of the print head.
2.  Click [Prepare] – [Extrudert], click [Load] , and 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 filament from the nozzle.
4. Clean the melted filament of the nozzle before printing.
   ‘ Notice: Consumables with different hardness have different requirements for the spring strength. The spring strength of the extruder can be adjusted! with an Allen wrench. When turning counterclockwise, the spring strength ‘is increased, and the spring strength is decreased clockwise.

Start printing

1. Insert the U disk into the printer’s USB port.
2. Click [Print on the main menu and select the model file.
3. When the nozzle and the heat reach the preset temperature, the X, Y, and 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.

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.

Software Installation
Tip: Copy the data in the U disk to the computer for saving. Our slice software is modified from Cura open source slice software, in order to better match with our company’s machines for printing and meet the needs of our customers. The software installation steps are as follows: Open the attached U disk file and select the path \ Software and Software Drivers folder \ ELEGOO Software folder \ Double-click the ELEGOO-Cura application to install it. Follow the prompts in the installation process to the next step. Finally, select the corresponding model of our company as shown below to complete the settings.

Troubleshooting Guide

A stepper of the X/Y/Z axis is not moving or making a noise when zeroed

• The stepper cable is loose. Please recheck the wiring connection.
• The corresponding limit switch does not trigger properly, please check whether there is any interference in the movement of the corresponding shaft and whether the limit switch wire is loose.

The nozzle kit extrudes anomaly
Check that the extruder stepper cable is not loose. ( Check whether the set screw of the extruder gear is locked to the motor shaft.

• The heat dissipation of the nozzle kit is not enough, make sure that the nozzle kit’s cooling fan is working properly.
• For clogged nozzles, try briefly heating the nozzle to 230°C and squeezing the filaments by hand to remove the clog, or use a fine needle to unclog the nozzle while it is warming up.

Model does not stick to the platform or Warpage

1. The key to whether the model can stick to the platform is the filaments are attached to the platform when printing the first layer. When printing the first layer, if the distance between the nozzle and the platform is more than 0.2mm, it will seriously reduce the model’s attachment to the platform, so it needs to be adjusted.
2. Set up the build platform attachment in Cura, and select the attachment type [Brim], which will help to enlarge the attachment surface and prevent warping and other problems.

Model misalignment

1. The travel speed or print speed is too fast. Please try to reduce the speed.
2. The belt of the X/Y axis is too loose or the synchronizer pulley is not securely tight.
3. The drive current is too low.

Severe wire drawing

1. Insufficient retraction distance, set the retraction distance larger when slicing If the retraction speed is too slow, set the retraction speed higher when slicing.
2. When slicing, tick the box “Z Hop When Retracted” and set the “Z Hop height” to about 0.25mm.
3. The print temperature is too high, which causes the filaments to become sticky.

Circuit wiring

1. Hotend thermosensitive (TH1)
2. Heatbed thermosensitive (TBO)
3. X-:X axis limit switch
4. Y-:Y axis limit switch
5. Filament detector (DET1)
6. Rear cooling fan/Model fan(FAN2)
7. Mainboard fan/print head fan(FAN1)
8. X/Y accelerometer interface(AC)
