@maziggy I started looking into this and a lot of the files already refer to the H2D Pro. I need to figure out what's actually missing since it's not available as a selection.

printer_models.py:

# Map from 3MF printer_model strings to normalized short names
PRINTER_MODEL_MAP = {
    "Bambu Lab X1 Carbon": "X1C",
    "Bambu Lab X1": "X1",
    "Bambu Lab X1E": "X1E",
    "Bambu Lab P1S": "P1S",
    "Bambu Lab P1P": "P1P",
    "Bambu Lab P2S": "P2S",
    "Bambu Lab A1": "A1",
    "Bambu Lab A1 Mini": "A1 Mini",
    "Bambu Lab A1 mini": "A1 Mini",
    "Bambu Lab H2D": "H2D",
    "Bambu Lab H2D Pro": "H2D Pro",
}

@maziggy That didn't work. It's odd it's not showing. Everything looks correct. I'll keep digging.

Oh, I see the problem ;) Haha

cd to bambuddy folder, then

git checkout feature/192 && git pull && cd frontend && npm run build

then (re)start Bambuddy.

I've tried it and it works.

@maziggy The printer is showing an error once the job was sent:

fail_reason = 117473298 print_error = 117473298 mc_print_error_code = 32786 reason = "Cann't find" Command that failed: extrusion_cali_get

H2DPro-Error.json

Add: Support Bundle

bambuddy-support-20260130-115736.zip

Going to see what I can figure out.

This is what I learned so far:

If I print using "Any H2D Pro" it fails as soon as Filament loading starts.
If I print by picking the specific printer, it gets past the Filament loading step to Nozzle cleaning.

What could be different in the new feature/printer_model_queue that would result in different behavior between these 2 methods for the H2D Pro?

I'm quite sure that has something to do with the ams slot mapping. We'll find out. Let me look into this tomorrow morning first.
