Machine Installation

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. Supplymentary Introduction 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

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 49-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.

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 filaments 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 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.

As shown in the picture

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.

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

1. Check that the extruder stepper cable is not loose.
2. Check whether the set screw of the extruder gear is locked to the motor shaft.
3. The heat dissipation of nozzle kit is not enough, make sure that the nozzle kit’s cooling fan is working properly.
4. 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 X/Y axis is too loose or synchronizer pulley is not securely tight.
3. Drive current is too low.

Severe wire drawing

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