Auxiliary Cooling Module Instructions

Users can adjust the rear cooling fan via a fan icon on the screen. The fan supports three modes: Silent, Normal, and Sport, selectable based on printing needs. The module can be turned off during silent printing.

Print Mode Description

The printing mode can be adjusted by clicking a speed icon. Three modes offer different settings for speed, acceleration, drive mute thresholds, and fan speed percentages during printing.

Auto Leveling

Calibrate the distance between the platform and the nozzle, aiming for the thickness of a piece of A4 paper.

1. Power on the printer and select "Level".
2. The printer's axes will home. On the leveling page, place an A4 paper between the nozzle and the platform.
3. Click the compensation value to adjust the nozzle-platform distance. Push and pull the A4 paper; when friction is felt, the center point calibration is complete.
4. Click the auxiliary leveling icon ?️. Calibrate 6 points on the platform by hand-twisting nuts. When the A4 paper can be pulled out but not pushed in, auxiliary leveling is complete.
5. Enter automatic leveling for calibration. The machine will heat up: nozzle to 140°C, hotbed to 60°C (preset hotbed temperature according to filament type for accuracy).
6. After reaching temperature, start the 121-point automatic calibration.
7. Once leveling is complete, set the Z-axis compensation: place an A4 paper between the nozzle and platform. Click the compensation value and adjust until friction is generated.
8. Click the save icon ? to save the settings.

Note: The leveling sensor only detects metal platform plates. Using a glass platform for leveling will prevent detection, potentially causing the nozzle to scrape the platform.

First Layer Adhesion Visuals:

• Case A: The nozzle is too close to the platform, resulting in insufficient extrusion.
• Case B: The extrusion volume and distance between the nozzle and platform are proper, with uniform adhesion.
• Case C: The nozzle is too far from the platform, leading to insufficient adhesion; the model may detach during printing.

When fine-tuning, switch the moving distance to 0.01mm or 0.1mm to prevent excessive nozzle pressure or filament hanging.

Model Test

Print Head Feeding Check

1. Push filaments to the bottom of the print head.
2. Navigate to Prepare > Extruder, click "Load". The nozzle will heat to 200°C.
3. Once preheated, click "feed" to extrude filaments.
4. Clean any melted filament from the nozzle before printing.

Notice: Adjust extruder spring strength with an Allen wrench for different filament hardness. Turning counter-clockwise increases strength; clockwise decreases it.

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 heatbed reach preset temperatures, the X, Y, Z axes will home, and printing will commence.

Notice: Observe the first layer during test prints. Adjust compensation settings during printing if needed to fine-tune the nozzle-platform distance.

Resume Printing Description

Power Loss Recovery

If power is interrupted or the machine is accidentally turned off, the printer can resume printing upon restoration of power. Simply click "resume". Note that while the PEI platform offers better adhesion when heated, it may cool down during extended power outages, potentially causing the model to detach, which could prevent successful resume printing.

Filaments Detection

This function alerts the user to replace filaments when a model is halfway printed, preventing print failures due to insufficient material.

Troubleshooting Guide

Stepper Motor Issues (X/Y/Z Axis Not Moving or Noisy)

• Cause: Loose stepper cable. Solution: Recheck wiring connections.
• Cause: Limit switch not triggering properly or obstructed. Solution: Check for movement interference and ensure limit switch wires are secure.

Nozzle Kit Extrusion Anomaly

• Cause: Loose extruder stepper cable. Solution: Secure the cable.
• Cause: Extruder gear set screw not locked to the motor shaft. Solution: Tighten the set screw.
• Cause: Insufficient heat dissipation for the nozzle kit. Solution: Ensure the cooling fan is working correctly.
• Cause: Clogged nozzle. Solution: Heat the nozzle to 230°C and squeeze filaments by hand, or use a fine needle to clear the clog while warming.

Model Does Not Stick to Platform or Warpage

• Cause: Excessive nozzle-platform distance (over 0.2mm) on the first layer. Solution: Adjust leveling and Z-axis compensation for proper adhesion.
• Cause: Insufficient build platform attachment. Solution: In Cura, enable "Brim" for enlarged attachment surface and to prevent warping.

Model Misalignment

• Cause: Travel speed or print speed is too fast. Solution: Reduce print speed.
• Cause: Loose X/Y axis belt or insecure synchronizer pulley. Solution: Tighten belts and pulleys.
• Cause: Drive current is too low. Solution: Adjust drive current settings (consult advanced documentation if needed).

Severe Wire Drawing (Stringing)

• Cause: Insufficient retraction distance or speed. Solution: Increase retraction distance and speed in slicer settings.
• Cause: "Z Hop When Retracted" setting not enabled or Z Hop height too low. Solution: Enable "Z Hop When Retracted" and set "Z Hop height" to approximately 0.25mm.
• Cause: Print temperature is too high. Solution: Lower the print temperature.
