It’s certainly one of my favourites. Wouldn’t want it all over my printer bed though. 
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. 
The thing with 3D printing is there is no right way or wrong way its finding what works for you 
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 
Yeah, most important thing about 3D printing is the 1st layer. 
its the foundation for the rest of the print.
This has gone way off topic now we should jump over to the new thread I’ve just created.
@PingSpike Rich if you want to tidy up this thread a bit and move the last few posts over to the general chat.
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
I have an ultimaker 2+ for some time now and I get excellent results
You won’t regret , I love mine and only had for 2 days lol Well done taking the step!!
It won’t be unboxed until the 25th May though, his retirement day.
Don’t you need to test it first?
Imagine your his disappointment if it didn’t work 
Tempting! 
Just Imagine all them plastic things you can make !!! I made my wife a Ipad stand and she is so happy, and quiet now, it works a treat !!
Like you’ve never said that before
That would be my 600mm lens, that I’m still not supposed to be using till the 26th of this month 
Ender 3 S1 is a superb machine, mine printed straight from out of the box and works everytime I use it.
Lol, it’s not even been unboxed yet. he we unbox it on the 25th
