-
Step-by-step
Assemble printer carefully
Tight frame = better prints
Loose screws = layer shifts
Update firmware (if applicable)
Many factory printers ship outdated
Level the bed
MOST IMPORTANT STEP
Paper method: paper should drag slightly
Set Z-offset
Too high = spaghetti
Too low = elephant foot
Load filament correctly
Cut filament at 45°
Push until you see extrusion
Print a calibration cube
Never print a big object first
Start with 20mm cube or Benchy
Tune temperature
Adjust in 5°C increments

Perfect first layer signs
Slightly squished lines
No gaps
Matte finish (not round strings)
Too High
• Filament round
• Not stickingFix: lower Z-offset by -0.05mm
Too Low
• Rough surface
• Elephant footFix: raise Z-offset by +0.05mm

PEI = Clean with alcohol
Textured = Slightly hotter bed
Cold room = Enclosure or brim
