This isn't new, is it? I remember treadmill printers being around for years already
No this isn't a new concept, the size and use of treadmill is not something I've seen before though.
To be honest, using an actual threadmill has no actual benefits other than generating an interesting headline
No i would think it's a significant disadvantage because they're (usually) using DC motors which have horribly inaccurate movement even with an encoder feedback.
I'm pretty sure they replaced all the running gear. I think the only thing they kept was the frame.
Creality has had a treadmill printer for a long time now. You are correct, this isnt anything new.
