RE: CORE One and soft TPU
I think you said you fed it from the top, how did you suspend the roll/etc., on the top?
I use this on other machines.

RE: CORE One and soft TPU
Right, I didn't mention that. I use a side spool holder and unspool filament from it so it didn't have mush drag. That's it, I just let filament hang on the side of the printer.
But Yes, I think I will design a magnetic spool holder that can be stuck on the top of the printer and remove when not needed.
RE: CORE One and soft TPU
I am printing 30D with a Bambu now, using a plywood platform and the polybox like I uploaded there. Not foolproof as it can free spool, but I will work on that too. It is easy to adapt that setup to the Core One.
As for why I don't print those on the Prusa, is the reasons you have outlined here.
RE: CORE One and soft TPU
I am using the Kit's core one and cheap TPU.
I am a beginner user and will share information with others like me.
My solution was to print the part from
https://www.printables.com/model/596608-nextruder-modified-idler-lever
(ABS infill 40%) and replace the part, and I reduced the printing speed to 70%.
To lower the printing speed, I added 'M220 S70 ; Will reduce all speeds in gcode to 70%' at the very bottom of the 'Start g-code' in Prusa Slicer. This has the same effect as lowering the speed to 70% with the knob during printing. (To set it to 60%, please change S70 to S60.)
Please note that all printing speeds will be at 70%
I haven't made any other modifications (I am supplying filament using a tube).
RE: CORE One and soft TPU
Maybe I don’t understand putting everything at 60%, why not change the speeds in the filament profile?
RE: CORE One and soft TPU
Has anyone tried this yet? It seems to be framed as the cure all for all of the nextruder’s TPU woes.

RE: CORE One and soft TPU
Separately, for what it’s worth I was able to print a full pair of kid sized Croc shoes using NinjaFlex (85A) on my stock core one. It required feeding the filament in by hand at the top of the nextruder after uncoupling the Bowden tube there.
I used the stock prusaslicer profile for Ninjaflex, (except lowered deretraction speed), and loosened idlers a lot.

Didn't you see my post on previous page? I explained what I did to manage to print 60A TPU, and this a one of the upgrade needed.
RE: CORE One and soft TPU
My bad didn’t realize it was the same part
RE: CORE One and soft TPU
I am doing this to simplify things without complicated settings. So, should I just write it in Firaments>Custom G-code>Start G-code?
