TPU  

RE: TPU

Sorry, I spoke too soon. Jams happened later.  Gotta find the right settings, like retraction minimal, detraction slow, Get the right setting on the idler.  I still love the printer for all the other filaments, though. I'm starting to think that the gear set up isn't ideal for TPU. In the meantime, my very long TPU print time on my MK3s+ is running smoothly along with never an issue. Don't have to babysit it at all.  So, maybe those long print times are OK since I can sleep through them.

RE: TPU

I always slow TPU prints way down without issue. Like all speeds at 40 slow.

My XL does print TPU well if I slow right down - so slow that for pure TPU it's as 'quick' and easy to use my MK3 while the XL gets busy with something else; a very good reason not to update every MK3.

Cheerio,

Ahh - Great info and great thought. Thanks guys.  I wish they made cars this way - upgradable for years and still robustly useable even when a new model is released. 

RE: TPU

I don't bother changing my print speeds for TPU, but I do limit speed using a low volumetric flow rate (last time I calibrated volumetric flow for flexibles was on my MK3 for NinjaFlex and came up with 3.61mm^3/sec). By using the filament setting volumetric flow rate I don't need to have a separate print setting for flexibles as the filament setting will take care of that for me. As always, YMMV.
