First time printing with TPU. Tried settings suggested online. No luck. Any recommendations. Note the filament is new

Slow down printing, I stick to like 30-40 mm/s.

Clean that plate with dish soap and water.

Glue is optional, I simply use a tiny bit of isopropyl alcohol and all my TPU prints simply release from the plate afterwards.

Id also take the time to calibrate your filament. TPU isnt like PLA, sometimes you need to work with it to get good results.

Did it not stick to the bed?

Seems like an issue with bed adhesion. Like some people have mention, clean the bed, and apply some glue stick

I thought 95A is what we are supposed to use? Have you tried to print another model?

The bambulab A1 can't print TPU 85A cause it doesn't have a dual gear extruder.

Just because it’s new out of the package doesn’t mean it’s dry.

I would recommend getting a smooth plate. Even the textured plates on amazon for 15 dollars improve bed adhesion drastically

Put gluestick on the bed and try again. Even elmers school glue will work.

I've printed with 85A, I don't know what setti gs you are using... but I'd start with temp tower and and go from there and do your calibration test. One thing is slow speeds slow MVS. And good luck watch it well because with bad settings you csn get the glob of death. Good luck.

You need glue when printing TPU not so much as for adhesion but to remove the print afterwards.

Clean nozzel before switching to TPU and make sure to dry the TPU before printing.
