Bambu Studio 02.08.02.61, macOS, command line with the full A1 system profiles (0.4 mm nozzle, 0.20 mm Standard, Bambu PLA Basic, Textured PEI; inherited settings merged as the app does), supports off. The message prints verbatim with exit code 156. Nothing was printed.

What is going on

Bambu Studio raises this when it plans the print and finds no extrusions at all (source). Slightly different sizes fail differently: a 0.3 mm cube stopped with the empty initial layer error instead, and a part thinner than the first layer gets "No layers were detected". PrusaSlicer uses the same wording (source).

FixSTL reported every part here as a clean solid and showed its size; it does not thicken walls or scale parts.

What was actually wrong

How to fix it

  1. Check the object's size in Bambu Studio: parts under about 1 mm may have nothing printable.
  2. Make walls, pins and text at least one line wide (0.4 mm with the standard nozzle) in your modelling program.
  3. If the part was scaled down by mistake, scale it back up and slice again.
  4. Check the file in FixSTL: it shows the part's size, but it does not thicken thin features.
