Usage Tips and Best Practices:

Getting the most out of your Prusa MK3S+ involves more than just hitting the print button. Here are some tips to ensure consistent and high-quality prints:

First Layer Calibration is Crucial: Spend time calibrating the Z height for the first layer. This is the foundation of a good print. Use the built-in calibration wizard and fine-tune until the filament is properly squished onto the PEI sheet, forming a solid and consistent line. Don’t underestimate the importance of this step. Small adjustments can make a huge difference.
Maintain Your PEI Sheet: Keep the PEI sheet clean. A quick wipe down with isopropyl alcohol (IPA) before each print is usually sufficient. For tougher residues, consider using acetone sparingly, but only when the build plate is cool. Avoid touching the printing surface directly with your fingers, as oils can affect adhesion.
Filament Storage: Store your filament in a dry environment. Moisture can cause various printing issues, including stringing, bubbling, and poor layer adhesion. Use airtight containers with desiccant packs, especially for materials like Nylon or PETG that are particularly hygroscopic.
Slicer Settings: Experiment with slicer settings to optimize for different materials. PrusaSlicer is the recommended slicer, as it’s specifically configured for Prusa printers, but Simplify3D and Cura can also be used with appropriate profiles. Pay attention to temperature settings, print speeds, retraction settings, and cooling fan settings for optimal results.
Bed Adhesion Aids: If you’re struggling with bed adhesion, consider using a brim or raft. These can provide a larger surface area for the first layer to adhere to, preventing warping or detachment. You can also experiment with bed adhesion additives like glue stick or hairspray, but use them sparingly and clean the bed regularly.
Regular Maintenance: Regular maintenance is essential for long-term reliability. Lubricate the bearings periodically, check belt tension, and clean the nozzle. Following the Prusa maintenance guide is a good idea.
Firmware Updates: Keep your printer’s firmware updated. Prusa regularly releases firmware updates that include bug fixes, performance improvements, and new features. Check the Prusa website for the latest version and instructions on how to install it.
Troubleshooting: Utilize the Prusa knowledge base and community forums for troubleshooting issues. The Prusa community is very active and helpful, and there’s a wealth of information available online.
