@nallath also on the UM3 ? How can I force Cura to do it ?

Any updates regarding new material profiles on the printer? My UM3 is running firmware version 5.2. I don't see the point in material profiles in Cura if I can't send them to my printer (need to always manually override). Thanks

In my opinion the errors/strange phenomenon is related to pressure changes in the nozzle. Some people use this effect quite artistically to paint pictures on objects. In the community it's known as velocity painting. ( https://www.youtube.com/watch?v=HdKaKKeyz7g&amp;t=435s <- recent video explaining it. Different filament do show this effect more some less. Ultimaker uses quite a lot of different speed changes and velocity to reduce effects like ringing. I think on the S5 even more than on the UM3 as it is bigger. I would cross out the 2nd extruder as the cause of this problem. Instead I would open all speed settings of Ultimaker Cura (Walls,infill, skin, top layers) and set them to about the same speed. If this doesn't help I would turn of all the different acceleration and observe the result. You might want to create a small model which prints in about a few hours to test all the changes. I also read that some people do put a dummy model like a box beside the print to reduce the effect.

Does anyone know a UM reseller who sells the S5 feeder or parts individually? The UM reseller I talked to said that they can't sell the S5 feeder or parts individually. Maybe @fbrc8-erin knows more about this?

Count me in, too ?

Don't want to hijack this topic, but does the new fimware also contain something else besides though PLA ?

Yes this would be great! I mean the settings are already saved why not the 3d models also ?

Great! Thanks for keeping us posted/updated @Daid ?

It doesn't prevent me from reading the full message, but it causes alot of scrolling which can get annoying for 2+ replies in the thread. If you look at the mails it's most of the time 5% reply and 95% other information. ( maybe a bit exaggerated ? but you get what I mean) I personally would prefer it if you would remove them again. I understand you intention, but those mails are IMHO for replies to threads which I choose to follow. The high value content could be send via weekly/monthly newsletter, which everyone can decide on recieving. You could translate the optimization you did for smartphones to bigger displays. On my iPhoneSE the blocks are way smaller and all belowh each other. Still I would prefer them to be removed for thread reply mails.

Yes they are. I tried to say that most other slicers, I think, don't differentiate between skin and walls like Cura and they just call them outlines,shells or skin. Therefore my confusion. Thanks for explaining the Cura specifics! Do you know why it's useful to have skins and walls separate instead of just using one setting to specify how many outlines the printed object should have?

@SandervG May it be possible to remove the added "you might also be interested in..." section you recently added to the e-mail notification? It was actually quite nice to be able to read all the post via mail client while on the go, but with this added section at the bottom it's a bit of a pain to read especially on smartphones:

May I ask whats the difference between skin and walls? It's a bit confusing why Cura has outer walls, inner walls and skin and each has a bazillion settings (overlap, extra skin...). Other Slicers most of the time only have walls or outline or skin.

Thanks @smartavionics for spending time debugging existing features and making Cura more predictable! ?

You should be able to get rid of the drag lines by changing "combing mode" to "no skin". It may sometimes not work as the "combing mode" isn't completely bug free, I think.

Great that you spotted this "wrong" behaviour @mechamecha and also reported it with a guide to reproduce! I will link @ctbeke as he worked on the adaptive layer feature. Maybe it's an easy fix.

@mechamecha Do you set your top thickness as mm or as layer count?

Are you guys looking into using 3d printed parts (SLS, Clip technology by carbon3d....) instead of injection molded ones? Allowing you to adjust even quicker. What are the drawbacks keeping you from doing so?

What are the challenges with the new aluminium build plates? I heared that they were delayed because of issues in the supplie chain.

Can you share one or two improvements, which have reduced the assembly time, as from looking at it you would guess everything is pretty much the same?

@SandervG do you only have blue Ultimaker shirts as work clothing? So your workers can choose to there taste, preference, liking ?

How do you deal with the demand? Reading interviews etc. the demand for Ultimaker printers is rapidly growing. Having to teach each assembly worker probably is a bottle neck?!

Out of curiosity. Whats the average assembly time of an UM2go/UM2+/UM3/S5? Which model can be assembled the quickest? Whats the deciding factor? My guess would be that the time to assemble an UM3 and S5 would be similiar.

Another question of mine would be what scheme dfo you use for the assembly of your printers. Does each person assemble one complete unit or does each person assemble a specific part. Do people move through the manufacturing facility or do they stay at there desk ?

Why does Ultimaker not reuse for example the build platform from the UM3 on the UM2+ series? To me this would make sense as you would only need to stock, source and assemble one build platform. Maybe I'm missing something or there is some good reason to not do it?!

Good point. Didn't think about that. I might try to create a mockup of the black version to compare it as it is hard to imagine how it may fit in. Maybe a UI/UX designer from Ultimaker can help us / has some Ideas to make it look more inline. I think this could be worked out, but for the time being I agree it's best to not change it. What do you mean by hamburger-style menu dropdown? Different Idea: What about putting the dropdown into the dropdown next to the search or maybe into cura preferences next to the dark theme?
