How to improve printing TPU on Ender 3 V2 and other Bowden Printers - reduce or remove stringing.

I have formulated a simple 3 step process that you can run when you get a new reel of TPU filament, to get the best out of each reel, since they seem to vary so much!

So watch it and hopefully this 13:35 (I know...I should have added 2 seconds of blank space..) video will save you hours of guesswork on how to print TPU on your ender 3 or whatever bowden printer you have (actually it should work on direct drive too).

6:20 - How to print a retraction distance calibration tower in cura
7:50 - How to print a temperature tower in cura
8:33 - How to print a retraction speed calibration tower in cura
9:20 - Why you may need to roll back the settings a bit from the best ones
9:28 - Why TPU bends in the extruder or pops out of the side or spins without moving
10:40 - Final settings
10:52 - Before and after the process.
11:07 - Why would you actually even print TPU with retraction turned off?
12:55 - Wrap up and conclusion.
