Question: If you have tried a dodgy dual input hotend, what were your experiences?
Background: As with anyone else who have a single extruder, I've been contemplating upgrading to something with a bit more flexibility. But the idea of getting a whole new printer doesn't appeal as much to my wallet, as it does to my mind :-)
Scouring aliexpress for weird filaments with the mrs - you know, normal Saturday-evening-and-the-kids-are-sleeping couple activities - we fell upon a dual input hotend for creality cr10. It looks an awful lot like the hotend we have, and it comes with either 24v or 12v heater. It's only about 15€ so I might just give it a try, but it's pretty stupid when I don't even have a plan for an extra extruder as well. And I don't know how I would go about wiring that part up on my cr6 at the moment.
Avoid. There's a good reason BambuLabs has one of the only somewhat working multicolor system on the market. Just buy an A1 and toss the CR10 in the trash unless you're doing this as a learning exercise and you like putting yourself through hell figuring out issues with your machine. I do happen to like doing that, and I still wouldn't do a system like this.
Not anymore. Creality K2 plus has multicolor, works great.
And the Qidi I-Fast, and the Prusa XL.
and the Anycubic Kobra combo, only one I know of with a heated filament dryer inside the MMU
