X/Y/Z Axis Motor Not Moving or Making Unusual Noises When Homing
1.Motor cables are loose. Please recheck the connections.
2.The corresponding limit switch fails to trigger. Check if there is any interference with the movement of the
corresponding axis and whether the limit switch cable is loose.
Abnormal Extrusion from the Nozzle
1.Check if the extrusion motor cable is loose.
2.Ensure that the extrusion gear is securely fastened to the motor shaft.
3.Insufficient cooling for the printhead. Ensure that the printhead cooling fan is working properly.
4.Nozzle clogged. Attempt briefly heating the nozzle to 230°C and manually extruding filaments with force to help clear the
blockage. Alternatively, use a fine needle to clear the nozzle while it is preheated.
Model Not Sticking to the Platform, Warping
1.The key to model adhesion is whether the filaments adhere to the platform during the first layer printing. If the distance
between the nozzle and the platform exceeds 0.2mm during the first layer printing, it will significantly reduce adhesion to
the platform, and re-leveling is needed.
2.In MingDa Orcaslicer, set the platform adhesion by choosing the adhesion type as "Brim." This helps enhance adhesion
and prevent warping issues.
Model Misalignment
1.Movement or printing speed is too fast; try reducing the speed.
2.X/Y axis belts are too loose, or the synchronous pulley is not securely fixed.
3.Drive current is too low.
Excessive Stringing
1.Insufficient retraction distance; increase the retraction distance during slicing.
2.Retraction speed is too slow; increase the retraction speed during slicing.
3.Set retraction Z lift during slicing, lift height around 0.25mm.
4.Printing temperature is too high, causing strong viscosity of the filaments. Lower the printing temperature slightly.
Printer Cannot Connect to the Computer
1.Computer and printer are not on the same local network; connect to the same local network.
2.Device is offline; check if the printer or computer is properly connected to the network.
Device Cannot Power On
1.Power failure; check the power connection.
2.Hardware failure; contact the manufacturer for repairs.
10. Common Issues and Solution
9. Maintenance and Care
Cleaning the Nozzle:
After printing is complete, promptly clean the residue on the nozzle using a tool and taking advantage of the nozzle's residual
heat. Avoid touching the nozzle directly with your hands to prevent burns.
Replacing Filaments:
Timely replace filaments based on the type and actual usage. It is recommended to use filaments recommended by the
manufacturer. Seal filament not in use for an extended period, as excessive exposure to moisture in the air can make the
filament brittle.
Checking the Platform:
Regularly check if the print platform is flat. If there is deformation or damage, contact the manufacturer or dealer for repairs.
Regular Lubrication:
Periodically apply lubricating oil to the lead screw and guide rails. During the operation of the printer, friction between various
parts occurs. Without proper lubrication, it can lead to wear and damage.
Software Updates:
Regularly update the printing software to improve print quality and efficiency.
