My First CoreXY

[curious aardvark]

Okay I really have to post the 'difference between us' photo's at some point lol.
There's you buying the latest all singing and dancing, extruder and there's me just having stripped an old mk8 out of my original flashforge creator - 'cos with a couple tiny bits of ptfe (which it already has), it will outperform the sapphire's current bondtech for flexible filaments and I doubt it will be any worse for harder filaments either :-)

Just got to design and print a mount for it and I'm good to go. lol

In the meantime a little epoxy putty has modified the existing bondtech to work really well with modern - stiffer then ninjaflex - tpu's.
At some point I'll use some more putty and hopefully get it working with the really floppy stuff.
Pretty much only because I still a roll of filaflex and a roll of original ninjaflex that i have never been able to use properly. Mainly because it's so bloody elastic and until last week my knp used rear mounted spools and the pull to get it into the extruder just stretched the soft stuff too much. It now has top mounted spool holders and (huh, okay I'm an idiot) would probably work - and I haven't tried yet !
lmao
Guess what I'm about to do lol

I think, to be justifying your approach, at some point, I want to see you printing at a true 100mm/s (at least) with a 0.8 or 1mm nozzle and at least 0.5mm layer heights.

If you can't beat my cobbled together machines and old school buck-store mods with your futuristic, state-of-the-art machines - it would be quite tragic.
