Following instructions to prevent harm during 3D printer operation.

Inserting filament into the hotend of the 3D printer.

Choosing the appropriate voltage (110V or 220V) for the 3D printer based on local standards.

Adjusting the 3D printer bed for consistent printing.

Settings controlling the 3D printing process, including temperature and software settings

Settings affecting the temperature during the 3D printing process

Settings within the software controlling the 3D print process

The part of the 3D printer that melts the filament.

Adjusting the height of the print bed to ensure it's parallel to the nozzle for accurate printing.

Using the Z-axis adjustment nut to fine-tune the height of the nozzle relative to the print bed.

A software used to prepare 3D models for printing on 3D Printers.

Importing a 3D file (STL, OBJ, etc.) into Cura software for printing preparation.

Removing any prior print model from the 3D printer platform in Cura.

Rotating, scaling, repositioning and viewing 3D models in Cura software before printing.

A Cura function to ensure a 3D model's flat surface is correctly positioned on the print bed, reducing adhesion issues.

Formats such as STL, OBJ, DAE, and AMF that 3D models can be saved and imported as in Cura software.

Locking the scale feature in Cura prevents uniform scaling along the X, Y, and Z axes. This ensures the model's proportions stay consistent during scaling.

The 'Layers View' in Cura allows you to visualize the individual layers of your 3D model before printing. This helps identify potential problems like skipped layers or gaps in the print path.

When saving GCode files in Cura, file names should only contain English letters, underscores, and spaces. Special characters are not recognized by printers.

The wire diameter refers to the thickness of the filament used for 3D printing. A common diameter is 1.75mm.

The nozzle size determines the width of the filament stream that is extruded onto the print bed. A common size is 0.4mm.

The speed at which the printer moves during the printing process, typically measured in mm/s. A recommended speed is 50-60mm/s.

Lowering the print speed for the outermost layer (the shell) helps create a smoother and more even surface finish.

The CH341SER driver is used to connect your 3D printer to your computer via USB. This allows for online printing control.

The printer can continue a print job after a power interruption, resuming from the point of interruption.

A device that detects when the filament is present and feeding through the printer, ensuring filament is flowing properly.

The nozzle can get blocked by melted filament, preventing material from flowing smoothly.

The ability of the first layer of a print to stick firmly to the print bed.

The amount of filament being pushed through the nozzle, controlled by the slicing software.

The temperature of the nozzle, which needs to be set correctly for the specific filament type.

Adjusting the height of the print bed so it's perfectly parallel to the nozzle, ensuring consistent print quality.

A setting that controls how much filament is extruded, calculated as a percentage of the default.

The top layer of a 3D printed object has visible gaps or hollow areas.

The 3D model is printed with too few layers, resulting in gaps and a less detailed final product.

The Fill value in the slicing software is set too low, leading to gaps in the object's internal structure.

Not enough filament is being extruded during the print, causing gaps and incomplete layers.

When filament is pulled too hard during retraction, resulting in visible stringing or thin strands on the printed part.

The retraction speed is too slow, allowing for more molten filament to be drawn out, leading to stringing.

The printed object starts to melt due to excessive heat from the hotend.

When the print head moves incorrectly, leading to misaligned layers and a distorted final product.

Uneven lines or bands appearing on the printed surface, usually caused by inconsistent filament extrusion, temperature fluctuations, or Z-axis misalignment.

The print bed or nozzle is not perfectly level or straight, leading to inconsistent layer heights and surface irregularities.

Sharp corners or edges on a printed object that appear jagged or uneven, often due to insufficient cooling or excessive printing temperature.

Visible lines or traces of the print path on the surface of the object, indicating excessive filament extrusion or Z-axis uplift.

Unwanted folds or creases on the printed surface, often caused by poor filament quality, temperature fluctuations, or a vibrating print bed.

Inconsistent filament flow causing uneven layer heights and surface irregularities, potentially due to feeding problems, clogged hotend, or incorrect settings.

A 3D printer motor making unusual noises or vibrating excessively, often indicating loose connections, obstructions, or technical issues.

The SD card used to store and print 3D models is not working properly, potentially due to corrupted files, unreadable formats, or physical damage.
