Printer Custom TPU profile temp not being used (solved)

Bambu Lab H2 Series
1

After trying TPU for the first on my H2D and getting a lot of string, I saw the temp was 20 over manufacturer’s recommendation. I updated it in the TPU generic profile and saved it, when I choose that in the prepare section, and slice, the machine seems to use the generic settings temp anyway. Anyone else running into this?

Make sure you are setting it for the correct nozzle, standard and high flow have their own temps and settings in general. Also make sure you are setting it not just for first layer but for both first and subsequent layers.

Thank you. I am using HF nozzles but changing the standard nozzle settings. It never occurred to me to click that dropdown and see that there are separate settings based on type of nozzle. I will try those other suggestions as well.

Thanx again.

Also after a lot of testing with H2D with HF hot ends and TPU I found the best way to reduce stringing is by lowering the temps. I pretty much completely eliminated stringing with generic 95A TPU and Bambu TPU 95A HF by lowering the temp to 230c for HF and 220c for regular TPU.
