I'm trying to print some lettering on the first layer, but the lettering material is in location 2 of my S5. By the lime the lettering is printed, the gaps left by extruder 1 are too small for the lettering to show through.
any recommendations?

I've been scanning/re-designing and printing some Guitar pedal enclosures this week. The idea is to save some pedalboard space so i can fit more pedals on my board :)
This prototype is printed in PLA at 0.2, but the final version will be Nylon.

This reminds me of a design i've been working on that is printed in the same way. But its based on a series of hexagons and pentagons which curl up and clip together to form a ball. Just small scale test prints so far, and i haven't had enough success to try a full scale print yet.

Hi guys, yes there were a lot of steep overhangs so I ran the Z-Hop option and that helped tremendously. My printer is just over a year old so I didn't think the pulleys were out of whack. Thanks though for all of your suggestions.
My S5 was about 7 days old when the pulleys went out of whack :)
Screws loosen over time through vibration, especially small ones ( & especially those that aren't tight in the first place!!!). Although it may not be the problem, a periodic retightening of the screws is recommended by ultimaker. That's why they supply the 2mm allen tool with the machines.

Hi Ultimaker Community,
I got a new UltimakerS5 a few weeks a go and while it is printing great I was a bit disapointed; I was expecting very precise dimensional prints...
I have listened to so many Youtube videos and found one on MakerMuse channel very interesting where Angus showed a tolerance/gap test. I just print my own tolerance test. I was expecting getting good results up to 0,2mm. Unfortunately, only the 0,5mm succeed (0,4mm & 0,3mm failed).
Is there any one that can print the gap test and share their results?
I was using Ultimaker Blue PLA filament at 0,15mm layer height and 20% infill using the "recommended" settings in Cura 3.6.0.
Attached is the STL and 3D STEP files.
ThanksTolerance test STEP.zip

had a few hours spare and printed this today...
Printed with Innofil PLA at 0.2 layer height with some custom settings.
0.2 and above were free to rotate.
used this custom profile 0.2 accurate.curaprofile

I don't know when this feature was implemented, but it is in the experimental settings, so I guess it is not in Cura 2.7.
It is explained here in detail if you are interested: https://ultimaker.com/en/resources/52672-experimental
very interesting read!

Just a quick update for those who are interested....Two very successful prints using this core, spool of filament and 130%material flow setting.

It's kinda hard to tell but Is it shifted in both X and Y directions?
If its just one axis it could be a loose pulley. Just tighten the pulley grub screw. (after axis alignment)
This happened to me a few weeks ago on a large print. But for two pulleys to go at the same time would be incredibly unlikely.
-
It survived, and it's looking great!
9 hours to go!
-
just out of interest, if the nozzle was to suddenly unblock itself... would the 130% flow cause the print to fail?
I'm leaving this one overnight and was considering what the risks are...
-
great thanks! That would actually make a lot of sense.
I was thinking about a clogged nozzle as a kind of binary parameter.... it is or it isn't. But of course it can be partially blocked aswell which may explain the fluctuating results. I had no idea wet filament could cause a blocked nozzle either!
All part of the learning curve i guess!
-
thanks for your input!I actually already bought a drybox today so we are very much thinking the same thing there!
Im pretty sure its not the filament tho. I was thinking it might be under extrusion so i tried upping the material flow to 130% in the tune settings and the last couple of layers are looking really good!
could all this be down to an incorrect setting in a profile?
-
OK so i have been closely monitoring this print all day and i have discovered some very unusual behaviour.
The print was going fine for the first few hours but then i saw the same thing happening as before. I was trying to find out what caused it when i touched the print head very lightly downwards and noticed that it INSTANTLY improved the print quality again.
i tried to show it in this short video...
hopefully you can see the line before i touch the head is terrible quality, then as soon as i touch the head everything returns to normal.
in the first couple of seconds of the video, the crackling can just be heard above the fans, and it also instantly disappears when i touch the head.
vibration maybe? under extrusion?
-
The nylon has been out in atmosphere on the machine for 2 weeks.... Is it possible that it's too wet? But the material already in the bowden tube stayed dry and therefore produced a good first layer???
edit- so i canceled the print, i wasn't happy with the way its looking especially as its for a client.
I have another, unopened spool of nylon so i thought i can print it with that instead, if my wet filament theory is correct. But before i did that, after clearing the bed, i restarted the print as a test to see if the first layer would be weird looking like the upper layers of the previous print....
To my surprise, the first layer went down perfectly, and now the 3rd layer is printing without issue also...so that rules out wet filament! The filament is fine.
Has anybody seen this behavior before?
My best (uneducated) guess now is that it was a partially blocked extruder, that was somehow unblocked when i restarted the print?
*as a side note, as i'm not sure its relevant, when i aborted the previous print the extruder still oozed for 30 seconds or more. Could this maybe indicate a blockage?
-
Today I started a large ultimaker nylon print. The first layer and brim went down great!! (left side of first image) But the next few layers seem to be furry and stringy, and I can hear a slight crackle from the nozzle.
Is this normal?
edit -
sliced with cura 4.0, and S5 is updated to latest firmware
Layer height is 0.1 (fine) all print settings are standard cura profile for Ultimaker nylon
-
Today i was able to update via the popup on my s5 over wifi without issue.
-
latest Cura is 3.6?

Hi Rudy, thank you for your message. I think everyone would have loved to see a different outcome. But still I believe this is better than releasing a product we do not fully support. I will send you a DM and we can look into an alternative compensation that would also add value for you as a user. Our apologies for the inconvenience.
Can I also receive that DM.
Thanks

.... Unfortunately, although i like your proposal of a discussion, the decision has clearly already been made. This will have been weeks if not months of discussions at Ultimaker to decide how to best handle this situation.
Ultimaker have come to the conclusion (and rightly so) that Existing S5 users will be compensated. It's Unfortunate however, that they have chosen an additional glass bed as compensation, instead of something that would actually increase the performance/capability of the printer such as for example additional Nozzle.
The retail price of the machine that we all paid, will have been calculated with the development and production of those Aluminium bed plates for the years ahead, in mind. The Cost of the machine can be altered (although it probably wont) for new customers, so really i find the inclusion of 2 glass beds in all S5s sold in future a strange choice.
-
I must say i'm disappointed.
The Aluminium bed was a big selling point for the S5! i cant understand why ultimaker think a 2nd glass bed is a suitable alternative....
-
thanks for the tips guys!
Yes the overhang may well be the culprit! kinda makes sense as where they fail is just where the overhang is starting to get big.
Indeed it is PLA, and i use a very thin layer of glue spread with a wet sponge i find works well. Im pretty sure its not bed adhesion issues as they are still well stuck to the bed when its time to remove them!

Heloo everybody,
My printer has been flat out on decorations and models for the kids this Christmas, but my latest print wasn't so successful...
What could cause 3 out of 5 front right moose legs to fall off like that? All seem to have happened at exactly the same way. But 2 are uninjured.
Any ideas?

I expected a little bit more details and I missed the "how to" of the title, but it was nice an had a very professional touch.
I thought we will get some info about how to setup Cura, are there some settings which are important to switch on/off and so on. But on the other hand, that would not fit into 30 minutes, so maybe I had the wrong expectations.
But anyway, it was good and I am looking forward to the next webinar.
well said!
I think the format, Presenter and interviewee worked very well. Both did an excelent job, and spoke clearly which is so important! I couldn't really see the reason for the Owens Corning video which must have been at least 25% of the allotted time, i would have preferred more QA, and a link to the video to watch after. I dont really see the point of any pre-recorded content at all in a webinar... Thats what youtube is for. I think anybody who is committed to watching a webinar at a specific time is likely a professional user looking for more detail and more complexity from the format in general. I cant say i really learned anything new today, but i guess it was nice to have the summary of my research confirmed.
That said, i did enjoy it and i'll definitely tune in for the next one!
Extruder 2 layers first?

Thanks for the tips!
the only way i could get it to work was to change the lettering color to extruder 1. It was a PITA, but its working now!
Thanks
