Recommended TPU 95A HF print settings?

Bambu Filament and Accesories
9

So I noticed the TPU HF settings are now available in the latest beta. And guess what … the only change is the maximum volumetric speed :rofl: I diff’d the JSON filament profiles just to be sure:

> jsondiff  Bambu\ TPU\ 95A\ \@base.json Bambu\ TPU\ 95A\ HF\ \@base.json  | jq
[
  {
    "op": "add",
    "path": "/filament_max_volumetric_speed",
    "value": [
      "12"
    ]
  },
  {
    "op": "replace",
    "path": "/filament_id",
    "value": "GFU00"
  },
  {
    "op": "replace",
    "path": "/name",
    "value": "Bambu TPU 95A HF @base"
  }
]

Currently doing a test print after drying overnight for 8+ hours. Last time I do admit I was a bit skimpy on the drying. My experience has been that I can get away with a four hour dry straight out of the silver bag – apparently not so this time! That first print came out looking like a total booger.

Here’s an interesting observation, before I could even get a print even starting to work: I had a ton of trouble getting the extruder to take a good grip on the filament! I ended up cleaning the 0.4mm nozzle with several cold pulls to make sure that was free of debris, then manually extruding and feeding the filament by hand until I could let go and see the extruder able to pull the spool by itself. It seriously took half a dozen tries. I have not experienced that with TPU on the X1C. It could be a foible of TPU on the A1M? Thought I would mention it in case anyone else struggles.

Pictures of the HF result forthcoming now that I have filament being laid down.
