What temperature should I print ABS on the Elegoo Neptune 4 Max?

Start at 245°C for the hotend and 100°C for the bed, then run a temperature tower across 235–260°C to dial in your exact filament brand.

What print speed works for ABS on this printer?

Around 84 mm/s is a safe starting point on the Elegoo Neptune 4 Max. It can go faster once the profile is tuned, but start conservative for clean walls.

What retraction should I use?

Use about 0.8 mm of retraction (direct drive needs very little). If you see stringing, raise retraction speed before distance and dry the filament.

Do I need an enclosure for ABS on the Elegoo Neptune 4 Max?

Yes — ABS needs an enclosure to avoid warping, and the Elegoo Neptune 4 Max is open, so add one or expect warping and cracking on larger parts.

ABS settings for the Elegoo Neptune 4 Max

Workable with mods

⚡ Quick answer: Print ABS on the Elegoo Neptune 4 Max at 245°C hotend, 100°C bed, 84 mm/s, 0% part-cooling fan and 0.8 mm retraction. Run a temperature tower to fine-tune your exact spool.

These are tuned starting settings for printing ABS on the Elegoo Neptune 4 Max. The Elegoo Neptune 4 Max has a direct-drive extruder with an all-metal hotend, so we set the hotend to 245°C and the bed to 100°C. ABS is a strong, heat-resistant engineering plastic that needs a stable, warm chamber.

⚠️ ABS warps and emits fumes — use an enclosure and ventilate the room. The open Elegoo Neptune 4 Max works for small parts, but expect warping on anything large.

Troubleshooting ABS on the Elegoo Neptune 4 Max

Problem	Fix
Stringing or fine hairs	Dry ABS before printing, drop the hotend a few degrees below 245°C, and raise retraction toward 1.2 mm. Damp filament is the No. 1 cause of stringing.
Poor first-layer adhesion	ABS slurry or glue on the heated bed; keep drafts away. Re-level the bed, set a slightly squished first layer, and wipe the sheet with IPA so it is grease-free.
Blobs, zits or rough walls	Slow the outer wall, enable coasting/wipe, and keep retraction near 0.8 mm. Keep the part-cooling fan low so layers bond and warping stays down.
