Full Bed First Layer Test Bambu Lab P1S / X1C

This is a full-bed first layer test model designed specifically for the Bambu Lab P1S, but it also fits the X1C .

The model covers almost the entire build plate (239.02 mm x 228.46 mm) and prints a single-layer sheet at 0.2 mm height. It’s ideal for checking:

• Bed leveling accuracy
• First layer adhesion
• Flow consistency across the whole plate
• Nozzle distance calibration

This test is especially useful when switching filaments, adjusting flow ratios, or tuning Z-offsets. It helps identify cold spots, uneven leveling, or adhesion problems before committing to larger prints.

✅ Works great with PLA, PETG, TPU
✅ Recommended speed: slower for the first layer (20–30 mm/s)
✅ Designed to stick but be removable without tools on a clean textured or PEI plate.

Enjoy!
