USER MESSAGES:
1. What are some good settings with normal pla and .4 nozzle to print flat parts on an adventurer 5m using orca
2. Im not having any problems with bed adhesion . I just want the top layer of the plat nice an smooth

ASSISTANT RESPONSES:
1. Here’s a solid “normal PLA + 0.4 nozzle + flat parts” setup for an Adventurer 5M in OrcaSlicer, tuned to reduce warping, keep bottoms clean, and get good dimensional accuracy. Profile baseline (good starting point) Layer / quality - Layer height: 0.20 mm (use 0.16 if you want prettier top surfaces) - First layer height: 0.24 mm - Line width: - Default: 0.42 mm - First layer: 0.45 mm - Perimeters (walls): 3 (2 is ok, 3 helps flat parts stay stiff) - Top / bottom layers: 5–6 (at 0.20mm) Temps (PLA) - Nozzle: 210°C first layer, then 205°C - Bed: 60°C first layer, then 55°C - If corners lift: keep 60°C the whole print Cooling - Fan: 0% for first layer, then 100% - Aux fan (if you use it): keep low/off for large fl…
2. Perfect — if adhesion isn’t an issue, then this is all about top-surface quality. On the Adventurer 5M + Orca, PLA can get *very* clean tops with a few targeted tweaks. Below is a top-surface-focused setup (no adhesion changes).. Key settings for a smooth top layer 1. Layer height & top thickness (most important) - Layer height: 0.16 mm *(0.20 is fine, but 0.16 noticeably improves tops)* - Top layers: 6–8 layers → Target ≥1.0–1.2 mm total top thickness (Prevents infill ghosting / texture bleed-through). 2. Top surface speed (slow this way down) This is usually the 1 fix. Orca → Speed → Top Surface - Top surface speed: 25–35 mm/s - Top solid infill speed: 35–45 mm/s The 5M can go fast, but smooth tops need slow…

EXTRACTED KNOWLEDGE / HOW-TO
- Layer height: 0.20 mm (use 0.16 if you want prettier top surfaces)
- First layer height: 0.24 mm
- Line width:
- Default: 0.42 mm
- First layer: 0.45 mm
- Perimeters (walls): 3 (2 is ok, 3 helps flat parts stay stiff)
- Top / bottom layers: 5–6 (at 0.20mm)
- Nozzle: 210°C first layer, then 205°C
