Ubis hot end

Have any other folks here used the Printrbot Ubis hot end? I was initially skeptical about their high and might reliability claims, but I have to say, this hot end has really grown on me. I tried many hot end designs before finally settling on the Ubis. I have two machines that have been printing literally 24/7 for months with Ubis hot ends, and I've never once had a jam!

These hot ends come assembled, and they're very cheap compared to other pre-assembled hot ends. Have other people had similar good experiences? I ask because it might be wise to point newcomers that way, since the hot end is a frequent source of problems, especially the ones that need to be partially or completely assembled.

I know it's not open-source, and that sucks. But I think it is very good for beginners. FYI I'm not affiliated with the Printrbot guys in any way, nor do I have a Printrbot. I just really like the hot end!

no 1.75mm?
no inventory?
no hope to get one.

Glad you have that aspect sorted out.
There are so many areas for issues, nice to have a few off your plate.

I'm glad your hot tip is working so well, I broke mine trying to extrude when it wasn't up to temp.. It came partually apart from the ceramic and abs started to coming out of the side. I took it out and cleaned it out but when I put it back it wouldn't heat up. Now I'm stuck as the printrbot.com are out of stock and no word when they will have any more.
Any idea where I cane get a new one?
