How to reproduce

1. Load AMS with Bambu TPU 95A HF and PLA.

2. Select the object "Gasket 1.step" in the attached .3mf and configure the filament for TPU.

3. Print the object. The print head will extrude the calibration lines. The print head will then go through the entire print process, without extruding a mm of filament.

4. Select the object "Test Object 20x10x1.5mm" in the attached .3mf.

5. Print the test object in TPU. The test object will print fine.

6. Seriously confused, select both objects to be printed in PLA.

7. Both objects print fine in PLA.

8. Select both objects to be printed in TPU.

9. The test object will print fine. Only half of the "Gasket 1.step" object will print, other than the outside walls, which will print in full. See attached photo.

Actual results

• No extrusion takes place while the print head goes through the motions of printing the entire object.

• When adding a second object to be printed, the print head will extrude filament for about half of the desired object, but not for the other half.

Expected results

Filament should be extruded during the entire print process of the object.
