Regular calibration, especially after transporting or making changes to your printer, is a key step to ensure consistently high-quality prints.

Checking for Mechanical Issues

Every intricate machine, like our Anycubic Cobra 3D printer, relies on the seamless operation of its mechanical components. Regular inspections can prevent bigger issues.

Belts: A primary culprit of layer shifting. Inspect for any signs of wear or slack. They should be taut but not overly tight. A plucked belt should resonate like a low-pitched guitar string.
Pulleys and Gears: Ensure they are free from debris. Over time, dirt or bits of filament can accumulate, causing irregular movements. Tighten any loose pulley screws.
Stepper Motors: These drive your printer’s movement. A malfunctioning motor might skip steps or overheat. If a motor feels too hot to touch, it may be failing or overworking.
Bearings and Rods: They should glide smoothly. If you notice any grinding or resistance, clean and lubricate them. Make sure rods are straight and free from dents.
Endstops/Sensors: Ensure they’re functioning correctly. If the printer doesn’t accurately detect its limits, it can easily result in layer shifts.

Examining the Print Bed

The foundation of any great 3D print is a well-prepared bed. Let’s ensure it’s in top shape.

Cleanliness: Any debris or oils (even from your fingers) can affect print adherence. Clean the bed using isopropyl alcohol and a lint-free cloth.
Leveling: While we touched on this in calibration, it’s vital to emphasize. A perfectly leveled bed ensures the initial layers stick well, preventing warping or detachment.
Adhesion: For trickier prints, consider using adhesion helpers. This could be painter’s tape, glue sticks, or specialized sprays. They ensure the print sticks but can also be removed easily post-printing.
Surface Inspection: Over time, print beds can get scratched or damaged. Ensure there are no noticeable divots or bumps which might affect the print quality.
Bed Temperature: Ensure the heated bed (if your model has one) reaches and maintains the right temperature. An unevenly heated bed can lead to print warping.
