Well, that wasn't simple at all. I cut pieces of flex long enough to be inserted into the bowden and then inserted the standard PLA into the feeder's wheels. That was enough for approximately 1/2 hours of printing, then a new piece of flex had to be inserted. The whole print took almost 7 hours... Other than that, everything was default - 220C, 40C bed, 0.2mm layers, 30mm/sec, 103% flow. The surface finish was perfect, the customer was ecstatic, and that what's really matter.

I did it!

Completely unrelated. @SandervG - I sent you a couple of PMs, can you please have a look?

Hi. Its lovely to see you here How are you also doing ? Im doing fine thanks. Became a daddy this year :)a beautiful little girl Im a very proud daddy and husband.. And my work is now creating fantastic medical products using 3d print technology. Which I love because I see men and women and kids running and walking better because of my work Best wishes and have a lovely day. Ian Hey mate! Sorry for the delay, was sooo overloaded with all kinds of crap. But, among the rest, I also do something similar to what you are doing: We joined the e-nable movement and also print hands as giveaway for the kids and adults who need them. I'm very excited, as it is my first hand ever made. Hope, the kid who asked for Spiderman colors will love it. Other than that, I will visit Berlin in November, to catch a bit of Christmas markets and to rest a bit, as the kids, you know, can be really annoying. :-) Happy printing!

That doesn't sound very encouraging... :-( If the experts like you have no clues, than could it be that UM2 simply can't handle that?

Ahhh, at last! With about two years delay, but better late than never, you know.

So, after oiling the bowden, the small to medium sized prints come out very good on my UM2 with Robert's feeder. However, the larger ones, that can take 6-8 hours are impossible yet. The Ninjaflex filament eventually slips away from the feeder gears and ruins the print. I use the recommended settings: 220C 40-50C bed 30 mm/s no retractions 2mm layers 103% flow And, of course, the Snap On Guide is on the feeder but eventually, it is not enough. Any ideas how to make it more reliable?

From here: All the links aren't working. On IE everything is fine, though.

The links to Cura downloads, manuals and the rest do not work on Chrome for all of my computers for a while.

Did as the doctors said, the prints look better for now. Hope, it will last. Thanks everyone for the help.

Sorry for being complete noob in that, how do I check it?

Why does that happen? The shorter sides are perfectly fine while the longer ones (Y axis) are uneven and ugly. The belts seem to be OK, as far as I can see and feel.

In that case I am more than 90% sure that you have added an Ultimaker 2+ to Cura, instead of an Ultimaker 2. Do you have a nozzle dropdown in the sidebar? I stick to the remaining 10% :-) There are nozzles dropdown, but without the possibility to add custom sizes. Will try to re-install that version of Cura again. Thanks for the help!

OK, I feel better with myself now:

In Machine Settings. I humbly admit that after spending some time and looking everything under the "Machine Settings" and everywhere else, I could not find where the new nozzle size can be defined. I have UM2 and do not know json. :-(

How do I set custom nozzle size (0.15mm) in Cura 2.7?

As usual since the "upgrade" of the forum - I normally open simultaneously one after another several tabs in Chrome - four or five, starting with this forum. The I read all of them, except the forum which just finishes loading by the time I browsed quickly thru the rest of the sites. That's why I rarely go here and did not visit Youmagine for ages.

Hey Ian! Wie gehts mate? It's good to see you around!

I must admit that all my attempts to find a suitable glass locally failed, too. The ones from Spain asked absolutely unreal price. So, if anyone has a suggestion for a supplier in Europe - all kudos due.

Thanks, will do! What is their contact information?

Hi @neotko, Thanks for the very informative post. Is it possible to order a couple of these glasses from you?

Yes. I had a chat with Formfutura representative (who was not really helpful beside citing the specs docs). I went for TitanX as it has much greater impact strength (58KJ/m2 vs. 18KJ/m2 of ApolloX) and is almost as strong in tensile one (43.6 MPa vs. 47.5MPa of ApolloX). Overall, I like this stuff. It is easy to print, nice surface finish, good layer adhesion, has some typical ABS odor, albeit much less than classical ABS.

I printed at 250C. Could that be that the filament was too wet from the air moisture? It did have a little bit of air popping up during the nozzle heatup phase but not during the print.

Eventually, I was not that much successful with the PC - the interlayer adhesion was too weak, I easily broke the part in one hand. On the other side the TitanX turned out great. I like this stuff! Thanks everyone for your advises.

How do you make it stick to the glass? And in general, what are the recommended print settings?
