2092 Error Troubleshooting

1. Phenomenon description

The temperature of the nozzle or heat bed exceeds the configured minimum or maximum (e.g., -14°, -100°).

2. Cause analysis

Thermal sensor disconnection on the heat bed or nozzle.

3. Troubleshooting and solution

Reconnect the thermal sensor wires for the heat bed or nozzle.

Check the screen for current temperature readings or manually heat the nozzle/heat bed to identify the issue, and replace the corresponding parts (nozzle kit/heat bed kit).

2561 Error Troubleshooting

b. Update to the latest firmware. If the error persists, identify when the error occurs and provide logs.

2. Screen Assembly Wobble After Mounting

1. Phenomenon description

After unboxing and attaching the screen to the machine, it was found that the screen had severe vertical wobble.

2. Troubleshooting and solution

You can stick the available sponge adhesives on the back of the screen and then reassemble the screen onto the base casing.

3. Poor Printing in Silent Mode

1. Phenomenon description

Silent mode printing has problems with insufficient heat dissipation and motor streaks.

2. Cause analysis

Printing speed and fan speed are reduced in silent mode.

3. Troubleshooting and solution

It is recommended to use the recommended parameters for printing/the printing speed must be above 200mm/s and the model fan speed should be 100%.

4. First Layer Adhesion Issues/Model not Sticking to Build Plate/Nozzle Scraping Infill

1. Phenomenon description

1.1 Model does not adhere to platform during first layer printing;

1.2 Model detaches from platform during printing process;

1.3 Nozzle scrapes fill during model printing process.

1.4 Leveling detection abnormal, nozzle too high from build plate.

2. Cause analysis

2.1 The Platform contamination, residual print marks on the surface, not properly cleaned.

2.2 The actual printing material does not match the slicing parameters; for instance, used non-Hyper PLA but selected Hyper PLA material parameters for slicing.

2.3 Long-term high-speed printing can easily cause vibrations that affect the platform.

2.4 Did not use official printing parameters (jagged filling), self-set parameters (other filling styles) resulted in nozzle scraping issues.

3. Troubleshooting and solution

3.1 Check the platform for any debris. If there are remnants of printing materials, heat the build plate to above 80 degrees Celsius to soften the material for easier cleaning.

3.2 If using third-party printing materials, select generic types, e.g., Generic-PLA; it is recommended to use Hyper printing materials for optimal results.

3.3 Before each print, it is advised to activate the print calibration function to prevent the issue of the first layer not adhering.

3.4 If there is a problem with the nozzle scraping the infill, please check if the infill pattern in the print parameter settings is set to zigzag infill, or directly print a pre-sliced file that comes with it for verification.

3.5 Compensation in the Z-axis direction can be achieved through Expert Mode - Z-axis offset. (Applicable only for the current print.)

3.6 Compensation adjustment in the Z-axis can be performed through the slicer software Gcode (Z) offset.

3.7 Automatic generation of edges/smearing solid glue for the print bed adhesion option can effectively prevent issues with models not sticking.

3.8 Ensure there are no foreign objects on the build plate and Y-axis motion area, no wiring is touching the build plate, and re-level the platform.

11. Camera Turns on Night Vision in Daylight

1. Phenomenon description

The camera's night vision mode activates even during the day.

2. Cause analysis

2.1 The night vision detection sensitivity is high; if the front detection area does not detect enough brightness, night vision mode activates.

2.2 The current firmware does not support disabling night vision.

3. Troubleshooting and solution

The current firmware does not support modifications. A future update will include an option to disable night vision.

12. Screen Freezes or Goes Black After Modifying the Mesh Bed via Fluidd

1. Phenomenon description

After modifying the mesh bed in Fluidd, the program becomes unresponsive, causing the system to crash and the screen to freeze or go black.

2. Cause analysis

The current firmware does not support modifying the mesh bed.

3. Troubleshooting and solution

Access the Fluidd web interface, delete all configuration files, then shut down and restart the machine.

13. Extruder Abnormality / Extruder Jam / Extruder Abnormal Noise

1. Phenomenon description

1.1 The extruder makes obvious abnormal noise, and no filament flows out of the nozzle.

1.2 The printed model has defects such as stringing, lack of material, virtual layers, and insufficient extrusion.

2. Cause analysis

2.1 Analysis of Abnormal Noise Causes:

• Filament tangled on the spool, causing the extrusion motor to lose steps.
• Filament residue stuck in the front casing of the extruder.
• Filament jammed between the extruder gears.
• Filament clogged in the nozzle throat.

2.2 Analysis of Model Issues:

• Incorrect slicing settings.
• Damaged extruder gear.
• Misaligned extruder gear installation.

3. Troubleshooting and solution

Resolving Abnormal Noise:

• Check if the filament is tangled and ensure the anti-tangle material rack is installed correctly.
• Verify if the filament is stuck in the extruder or blocked in the throat.
• Heat the nozzle to 240°C (depending on filament type), unlock the extruder gear, and pull out the Teflon tube.
• If the filament can be manually pulled out, it indicates a throat blockage. Refer to after-sales video for nozzle cleaning.
• If the filament cannot be pulled out, it indicates an extruder blockage. Refer to after-sales video for cleaning the extruder.
• After cleaning the extruder, inspect the gears for damage and proper alignment.

Resolving Model Issues:

Check if the extruder gear is damaged or misaligned. If so, contact after-sales service.

14. Motor Port Clogged by Filament While Printing

1. Phenomenon description

The motor port is clogged by filament during printing.

2. Cause analysis

2.1 Incorrect filament input method.

2.2 Motor wires interfere with filament. Standard motor wire length is around 70 mm out of the bottom shell hole.

3. Troubleshooting and solution

• Refer to the operation video to correct filament input method.
• Check if motor wires are too long.
• Use the latest side material rack.

15. Printer Restarts While Hotend/Hot Bed Heating

1. Phenomenon description

The machine restarts during self-check or printing when heating.

2. Cause analysis

2.1 Improper power gear adjustment during assembly.

2.2 Insufficient switching power supply.

2.3 Short-circuited hotend kit.

2.4 Short-circuited hot bed.

3. Troubleshooting and solution

3.1 Adjust the machine to local voltage specification.

After adjusting voltage, if the machine restarts during heating, perform the following checks:

3.2 Isolate heating of hotend and hot bed to identify which causes restart.

3.2.1 If the hotend causes restart, unplug hotend kit flat cable and test.

• If heating is normal but the machine reports an error, replace the nozzle kit.
• If the machine restarts, check the mainboard or power supply stability with a multimeter. A stable 24V indicates a motherboard problem, otherwise a power supply issue.

3.3 If the hot bed causes restart, unplug hot bed heating wire and test.

• If heating is normal but the machine reports an error, repair the hot bed kit.
• If the machine restarts, check the mainboard or power supply stability with a multimeter.

Uneven Mesh Bed

1. Phenomenon description

The bed levelling appears uneven as shown in the picture.

2. Cause analysis

2.1 Loose strain gauge wiring.

2.2 Uneven torque on strain gauge fixing screws.

3. Troubleshooting and solution

3.1 Check and clean any debris under the strain gauges, ensure wiring is tight.

3.2 Slightly loosen all fixing screws for strain gauges, clean nozzle and platform and retest leveling.

3.3 If the issue persists, replace the leveling plate and strain gauges.
