On a sensible note, my slicer sets the bed temperature at zero (ambient) for TPU and I’ve never had any adhesion issues. In fact, I’ve actually heated the bed to 50-60 after printing to help removal.
Which is exactly why I got my printer for free, the muppets that were using it could never get it to work so they bought a new one to replace it. I got it home, done the bed and nozzle height and had my first print out in half an hour
I have it slightly higher than with pla and PETG and have now resorted to pritt stick for that as well as pla/petg now. Works a treat. In using saints smart TPU. Windolene gets pritt stick off (or cheap home bargains blue window cleaner). Works well for me but there are other good bits of advice out there
