Description of Special Function

Continue: For any further assistance or queries, please contact our customer support team.

• This function allows you to resume printing if you want to continue printing after the model has been interrupted by a misoperation.
• First click 【Tool】-【Home】, observe if the model will collide by setting the X/Y/Z axis to zero in sequence. (If a collision occurs, turn off the power immediately, this function cannot be used.)
• Then click 【Back】-【Move】, move the Z-axis to the height of model interruption, then move the X/Y axis again, and move the nozzle to the top of the model. Observe whether the nozzle is level with the model section or there is a gap of about 0.1mm. (The print head should not be lower than the height of the model interruption position, or model collision will occur during printing.).
• Finally, select 【Settings】 on the menu, click 【Continue】, and then select the model file you want to continue printing.
• Wait for the temperature of the nozzle and heatbed to reach the preset temperature, in the meanwhile, start to read the previous printing information up to the height of the interrupted printing position, then the X and Y axes will back to zero one after another, and then it will start printing.

Continue: 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.
Filaments Detection: This function is designed to effectively prevent the model from being scrapped after running out of filaments during the printing process by alerting the user that filaments need to be replaced before the model can be printed again.

Platform Leveling

• In the process of printing, we need to level the platform in order to make the base of the model stick to the build platform and not falling off.
• The best distance between the nozzle and the platform is 0.1mm-0.2mm, and you need to prepare an A4 paper to assist in leveling.

1. First, make sure that all the cables are connected, and then turn on the printer.
2. Click【Tool】in the main menu to enter the tool interface and then click【Leveling】.
3. Place a piece of A4 paper between the nozzle and the platform. Click the leveling point, and the nozzle will move to each point of the platform accordingly. Adjust the leveling nut under the platform. (Loosen the nut clockwise, then the platform will rise; otherwise, the platform will fall).
4. Make sure the nozzle and A4 paper just touch, the paper can move smoothly and there is friction force when moving the paper.
5. Level the point 2, 3, 4 and 5 in the same way.
   • After the leveling is completed, the distance between the platform and the nozzle must be verified (1-2 times) according to the above steps ① → ② → ③ → ④ to avoid scratching the platform plate.

Supplementary Introduction of Leveling

Special Case 1:

1. When the machine returns to zero, the nozzle is far lower than the platform. (Even if the four leveling nuts below the platform are tightened, the nozzle is still pressing against the platform.)
2. When the machine returns to zero, the nozzle is far higher than the platform. (Even if the four leveling nuts below the platform are loosened, the nozzle is still a certain distance from the platform.) Solution: Adjust the limit screw of Z axis to a suitable position.

Special Case 2:

1. The backboard of X axis is pre-adjusted before shipped out but during transportion it might get loose. If you find the printing head shaking or loose please use the open-end wrench to fasten the hexagonal isolation spacer until it moves smoothly without any wobble.

Model Test

Extrusion inspection

1. Push the filaments to the bottom of the print head.
2. Click【Tool】- 【Extrude】 , and then click 【In】, the nozzle temperature will be automatically heated to 200°C.
3. After the nozzle is preheated to 200°C, click [In], and the filaments can be spun out normally from the nozzle. The speed of extrusion can be selected as low, medium or high.
4. Please clean off the extruded filaments from the nozzle before printing.

Start printing

1. Connect the USB flash drive with printer.
2. Click 【Printing】 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.

Tips: When printing the test model, please observe the printing situation of the first layer. If the situation of A and C appears in the first layer, it proves that the five-point leveling is not well adjusted, so it is necessary to fine-tune the leveling nut under the platform or reset the platform. If the situation of B appears in the first layer, it proves that a good printing distance has been reached between the nozzle and the platform, and printing can be continued.

Software Installation

Tips: Copy the data in the U drive to the computer for preservation.
Our slice software is modified form Cura open source slice software, in order to better match with our company’s machines for printing and meet the needs of our customers.

If your antivirus software determines that it is a virus, you can close your antivirus software for a while and then continue to install the driver software.
• After the driver installation is complete, reconnect the USB cable, open the ELEGOO slicing software, and then click on the monitor, if it display the printer model and other information, the computer has been successfully connected.
• After importing the model, set the print temperature, layer thickness and other relevant information, and then click on the 【slice】, select the USB online printing.
• The power cannot be cut off and the computer cannot go into screensaver or hibernation mode when connected to printing via USB cable to prevent data transfer failure.

Troubleshooting Guide

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

1. The stepper cable is loose. Please recheck the wiring connection.
2. 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.

• Nozzle kit extrude 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 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
  • 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.
  • 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
  • The travel speed or print speed is too fast. Please try to reduce the speed.
  • The belt of X/Y axis is too loose or synchronizer pulley is not securely tight.
  • Drive current is too low.
• Severe wire drawing
  • Insufficient retraction distance, set the retraction distance larger when slicing
  • If the retraction speed is too slow, set the retraction speed higher when slicing.
  • When slicing, tick the box “Z Hop When Retracted” and set the “Z Hop height” to about 0.25mm.
  • Print temperature is too high, which causes the filaments to become sticky.
