Setup Guide

PLA Temperature & First-Layer Settings

The no-nonsense starting values and adjustment logic for dialing in clean first layers every time.

Most failed prints happen in the first layer. Get your temperature and Z offset right, and the rest usually takes care of itself. This guide gives you practical starting values and tells you exactly what to adjust when something looks wrong.

🌡️ Nozzle Temperature

Starting Range: 190–220°C

PLA prints comfortably between 190–220°C depending on brand and color. Start at 200°C and adjust from there.

Too cold (<190°C): Under-extrusion, weak layer adhesion, gaps in perimeters
Too hot (>220°C): Stringing, blobbing, oozing on travel moves
Dark colors often print better 5°C cooler; white/clear often need 5°C hotter

💡 Tip: Print a temperature tower (free on Printables) to find your filament’s sweet spot in one print.

🛏️ Bed Temperature

Starting Range: 55–65°C

A heated bed helps PLA stick on the first layer and release cleanly once cooled. Start at 60°C.

Too cold: First layer warps or lifts at corners
Too hot (>70°C): Print can stick too well and warp on removal
Glass beds: 60–65°C. PEI spring steel: 55–60°C. BuildTak: 55°C

✅ Verdict: 60°C is the right starting point for 95% of PLA on most bed surfaces.

📏 First Layer Height & Speed

Height: 0.2mm | Speed: 20–30mm/s

A slightly squished first layer is good — it creates mechanical adhesion with the bed surface. Your first layer should look slightly wider than subsequent layers when viewed from the side.

First layer height: 0.2mm (100% of nozzle diameter for 0.2mm nozzle, 50% for 0.4mm)
First layer speed: 20–30mm/s — slower gives better adhesion
First layer fan speed: 0% — let it stay warm to bond to the bed

⚠️ Common mistake: Running the first layer at full speed. Slow it to 25mm/s and you’ll fix most adhesion problems instantly.

↕️ Live Z Offset Adjustment

Dial This In Before Everything Else

Z offset is the distance between your nozzle and the bed at the home position. Too high and filament won’t stick. Too low and you’ll scratch the bed or clog the nozzle.

What good looks like:

Lines are slightly squished — you can see them merge at the edges
No gaps between lines
Surface looks smooth, not bumpy or raised

What to fix:

Lines not sticking, spaghetti, curling up: Lower Z offset (move nozzle closer)
Nozzle scraping, no extrusion, scratching bed: Raise Z offset (move nozzle up)

💡 Tip: Adjust in 0.05mm increments while the first layer is printing. Most printers let you do this live from the screen.

✅ Quick Settings Reference

Setting	Starting Value	Adjust If…
Nozzle Temp	200°C	Stringing → lower; under-extrusion → raise
Bed Temp	60°C	Warping → raise; won’t release → lower
First Layer Speed	25mm/s	Poor adhesion → slow down further
First Layer Fan	0%	Leave at 0% for first layer always
Z Offset	Per-printer	Not sticking → lower; scraping → raise

🏆 Bottom Line

Start at 200°C nozzle / 60°C bed / 25mm/s first layer. Dial in Z offset until lines are slightly squished with no gaps. That combination handles 95% of PLA on 95% of printers.
