"print successful" but skipped the last 20 or so layers

Bambu Lab P1 Series Troubleshooting

10/2 update:
Last night I took about a 30 degree section of my model that included the threaded opening, exported it to STL and STP and sliced it in Bambu studio. Both of these models printed through to completion(sorry forgot to snap a pic). I’m stumped. Is it possible that the Model was corrupted in the export process? all of the successes have been net new exports of the exact same model(or small sections of it) The only other variable is that I am trying to print this in ABS and all my tests were in PLA. This morning I started a print of the full model in ABS after re-exporting it to STP. stay tuned, and Thank you all for your idea’s and expertise.

Thanks for the update. This is exactly the outcome I was hoping for. To answer your question, this may be a model complexity issue or simply a corrupt model. Exporting and reimporting using different programs can apply different algorithms, which, although time-consuming due to the trial-and-error process, often yields results.

Given your model picture, if it fails again, here’s what I might suggest. Since this section(picture below) of your model is different from the rest, try one of two approaches:

  1. Cut out the section with this feature and print the remaining model to see if it reproduces the error.
  2. Cut out that section and print only that part to see if there is some kind of interference.

Update 10/7
Every test I printed with some subsection of this model(with and without the threaded opening) printed without any issues, only the Full model would fail.

I wish that I had the opportunity to test all of these individually to get a definitive root cause but given life, one or more of the following things solved this issue for me:
1.) Modified my model to reduce the pattern density, (slightly fewer holes)
2.) Modified my model and added 2 1mm rings to stabilize the vertical columns and improve print quality.
3.) within Orcaslicer I clicked “fix Model”(Just because, Just in case it was a corrupted model)
4.) Sliced and printed via OrcaSlicer

I’m going to consider this resolved and move on with my life :wink:
appreciate everyone’s feedback and assistance.
