This looks very nice. If you make any changes to the BOM or the drawings, be sure to include them on your product pages please.

Thanks,

What size PTFE tubing would I need to run 1.75mm filament. 4mm OD and 2mm ID?
How long?


Thanks
Roy

I agree that looks nice and I appreciate that you mentioned the original one, very fair.
...but reading "acrylic" there really surprised me! Can you elaborate on that choice? Wouldn't temperature be a problem for it?

@jebba - All will be available soon. We want to make one small change more, I need to wait on new parts and test it.

@Sound - temperature is not a problem for this acrylic, but there is one but, required is cooler fan. I'm not satisfied in 100%, and we changed materials in some parts (because some people not used cooler fan) - now we are waiting on new parts from factory and finally test it

Is this hot end compatible with the prusa lm8uu x carriage? [reprap.org]

Looks nice, sort of like the Lulzbot hot end

Has anyone been using this hotend?

The Lulzbot hotend is what I was planning on buying but it has been out of stock so this appears to be another option if it works as advertised.

Na Ebayu jest ta sama głowica z Chin i pewnie jest tego samego producenta. W Reprapach nie powinno sie stosować chińszczyzny tylko promować własne produkty.

Lulzbot has hotends in stock again, now a new version 2.0

Can anyone give feedback on this hot end?

My (rarely updated) Prusa i3 build log: [3dtheorist.wordpress.com]

This hot end is good as long as you don't need spare parts
problem is the changes and the threads are a bit off spec.
And it is hard to get a hold of these people
left 3 messages on e-bay about this hot end no reply in the last few days
