Machine Installation

Attached U disk with an installation instruction video.
Print head installation: Use 3pcs (PM3*14) screws fo 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.

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.

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.

The ausiliary cooling module can be turned off during silent printing,

Auto Leveling

When firstrunning 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 .

• Whenthe printeris poveredon, select [Level]
• Eachaxisof theprinter automatically returns to the home position, after entering the leveling page, place a piece of A4 paper between nozleand the platform, and click the compensation value to adjust the distance between the nozzle and the platfom (See Picture 2), push and pullthe A4 paper, when there s frction generated, the center point calibration can be completed. Click on the auxilary leveling ( } . calibrate the 6 points of the platform with the A4 paper by hand-twisting nuts, and push and pull the A4 paper, when the paper canbe pulled out but not pushed in, the auxliary leveling can be completed.
• After completing the auxilary leveling, enter the automatic leveling ( ) for automatic calibration
• The machine will enter the heating state:the nozzle s heated to 140°C, the hot bed is 60°C.(Please preset the hot bed temperature according tothetemperature of the consumables to achieve a more accurate leveling value)
• After reaching the preset temperature: start the 121-point automatic calibration.
• Afterthe levelingis completed, set the Z-axis compensation: placea piece of A4 paper between the nozze 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.
• Clickthe saveicontosave.[ ]

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 ofthe nozzle will be automatically heated to 200°C.
3. Afterthe 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 1 for the spring strength. The spring strength of the extruder can be adjusted 1 ith an Allen wrench.
When turning  ounterclockwise, the spring strength the spriii Start printing

1. Insertthe U disk into the printer’s USB port.
2. lick [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 1printing. 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

As shown in the picture:

When fine-tuning, please switch the moving distance to 0.0Imm 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

Astepper 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 shaftand whether [GIo1E) 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 kitis 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 itis 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 thefirst layer, i 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. Setup 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 s too fast. Please try to reduce the speed.
2. The belt of XY axisis too loose or synchronizer pulley is not securely tight.
3. Drive currentis too low.

Severe wire drawing

1. Insufficient retraction distance, set the retraction distance larger when slicing
2. Ifthe 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.

Circuit wiring

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