Nylon Settings for Longer LK5 Pro

Temperature Settings

Start with the nozzle at 260°C and the bed at 80°C. If you see poor layer adhesion, increase the nozzle temperature by 5°C increments. If you experience stringing, decrease the nozzle temperature by 5°C. For the first layer, you can increase the bed temperature by 5°C for better adhesion, then let it drop back to 80°C for subsequent layers.

The Nylon filament has a recommended nozzle temperature range of 240-280°C and a bed temperature range of 70-90°C. The Longer LK5 Pro supports nozzle temperatures up to 260°C and bed temperatures up to 110°C, which fully covers the recommended range for this filament.

Speed & Quality

For the Longer LK5 Pro, a print speed of 30-50 mm/s works well with Nylon. The first layer should be printed at 15-25 mm/s for solid bed adhesion. Outer walls at 70-80% of the main speed produce cleaner surface finishes.

For quality-critical prints like miniatures or display pieces, reduce the speed to 30 mm/s and use a 0.12-0.16mm layer height. For draft or rapid prototyping, you can push the speed to 50 mm/s with a 0.24-0.28mm layer height. The standard 0.2mm layer height at 40 mm/s provides the best balance of speed and quality for most prints.

Bed Adhesion

Nylon is notoriously difficult for bed adhesion. Use a PEI sheet with glue stick, or a Garolite (G10) sheet for the best results. A brim is essential for most nylon prints. Some users also find blue painter's tape with glue stick works well.

Common Issues with Nylon on Longer LK5 Pro

Here are the most common problems you may encounter when printing Nylon on the Longer LK5 Pro, along with proven solutions:

• Warping: Use an enclosure, brim, high bed temp, and ensure a draft-free environment
• Bubbles or popping during printing: Filament is wet -- dry for 12-20 hours at 80°C
• Poor layer adhesion: Increase nozzle temperature, reduce fan, and ensure filament is thoroughly dry
• Stringing: Almost always caused by wet filament; dry it thoroughly before printing

Tips for Best Results

Follow these expert tips to get the best possible prints with Nylon on your Longer LK5 Pro:

• Drying is absolutely critical -- even new sealed spools benefit from 12+ hours of drying at 80°C
• Print from a dry box or active filament dryer; nylon re-absorbs moisture during the print
• Garolite (G10) sheets provide the best bed adhesion for nylon
• After printing, you can boil nylon parts to moisture-condition them -- this triples impact strength
• Start with PA12 if you are new to nylon; it is much easier to print than PA6

Support Settings

For prints requiring supports with Nylon, use tree supports for easier removal and less scarring. Set a 0.15-0.2mm Z-distance between support and model. If you have a dual-extruder setup, consider PVA (for PLA/PETG) or HIPS (for ABS) as dedicated water/solvent-soluble support material.

Longer LK5 Pro Specifications

The Longer LK5 Pro features a 300 x 300 x 400 mm build volume with a maximum print speed of 180 mm/s. It uses a Bowden extruder system, which is lighter on the print head but may require additional tuning for flexible filaments like TPU. The hotend can reach 260°C and the heated bed supports temperatures up to 110°C.
