This needs to be explained somewhere. "Modern" doesn't mean anything.
For example in:
- The Readme at: https://github.com/Ultimaker/Cura/
- Release descriptions at: https://github.com/Ultimaker/Cura/releases/
- Systems requirements page: https://support.ultimaker.com/hc/en-us/articles/360011788040-What-are-the-system-requirements-for-Ultimaker-Cura-
-
@jpyt, Ultimaker actualy has done something like that for the Ultimaker 3.
See: https://ultimaker.com/en/resources/23132-clogged-print-core

I'm also having this issue. It's especially problematic when you want to print something with text on the bottom, like the OpenScope case:
https://www.thingiverse.com/thing:2080883/#comments
I'd also prefer a setting in the firmware, but maybe a Cura plugin would be the fastest route?
-
I understand from the update that there is a plugin browser comming in the next Cura. I understand from the code, that it's retrieved from:
http://software.ultimaker.com/cura/v1/plugins
I'm asumming this is currently managed manually? Are there any docs on requirements? How could we submit plugins?
The Cura manual seems to be targeted on the current stable version and doesn't seem to contian info yet.
I've also looked into the master and 2.7 branches of Cura.
Thanks!

Won't changes like this disappear on an updates? Is it likely that this tweak is included in the next firmware update?
-
Thanks! I'll apply those tweaks. They make it wait a few seconds before restarting it and waits a second before checking it started successfully?
Got that from: https://www.freedesktop.org/software/systemd/man/systemd.service.html
That service isn't prefixed with griffin because it's an existing service?
-
I noticed that my Ultimaker 3's camera stopped being available a couple of times.
Looking into it it seems like it's the http interface (http server?) that stopped?
Some observations:
- I can still ssh into the ultimaker
- "systemctl status griffin.camera.service" indicated that the camera service was active (running) and showed no warnings or errors.
- "systemctl status griffin.interface.http.service" indicated it failed.
Full output:

I need to do a reboot the internal computer (sudo reboot) or the whole printer for it to start working again.
Let me know if I can share more information.
-
@ahoeben, was thinking the same. Altough... there is the permission check and port 80 excludes ssh. Maybe I'm paranoid?
@ultiarjan, any tips on how to set that up? Would that be usable to access it from a server, to publish a limited api to the public?
-
I've sort of started with a dashboard: https://github.com/peteruithoven/um3-dashboard
But this is currently only showing the camera, using the unofficial mjpg stream, which I've made accessible through my router.
I could really use some tips on how I could for example only have my server be able to access my printer so that I could provide a limited read-only api for the dasboard, maybe using a vpn.

In the end we received the error again and we replaced the bed with a new one.

Looks like Cura 2.4 contains improvements that should improve pva on pla adhesion (tweaked jerk and acceleration).
https://ultimaker.com/en/blog/35482-cura-24-beta-is-here
Haven't tried this myself yet.

It's also possible if you group objects, ctrl click the object you want to put above the rest and translate it.
I'm not quite sure what this fixes?
That you don't need to disable any settings in preferences.
Ah! Nice, thanks! I didn't realize there was a difference between shift and ctrl. Very useful.

You could also try not printing it as support, but an object sandwich of sorts (you put another circle in between and mark it as print with PVA nozzle)
That sounds like a very interesting solution to the following issue, but doesn't affect the adhesion?
-
With the Ultimaker's PVA we where experimenting with stacking multiple similar models on top of each other. This could highly decrease the amount of manual intervention when doing bigger productions.
This is possible after disabling the following behavior in the Preferences:
- Ensure models are kept apart
- Automatically drop models to the build plate
For easy separation and good prints we where thinking of adding a thin pva support (possibly interface) layer in between them.
But the pva has a really hard time adhering to the pla, even though the Z distance is 0.
What does work is setting the horizontal expansion to something like 1, which creates a pva ring around the model to which the thin in between layer adheres. But this takes a lot more time to print because now it has to switch nozzles every layer. See:
We had a similar problem when printing the following model, here we also needed the pva to touch the buildplate for it to print properly on the flat surface.
Any tips / ideas on how this could be done without having pva on almost every layer?
-
So since moving water and heat helps, couldn't we simply use a small aquarium? Probably preferably with few elements in the aquarium itself?
-
Thanks guys! I did already tried adding 'http://', but that didn't help. But adding the slash before the query fixes it.
So in my case this url works: 'http://10.0.0.106:8080/?action=stream'
-
One small addition:
VLC media player can display (and record) the camera stream as well.
How does this work? VLC can open a network stream, but opening one of the following doesn't work:
- {ip}:8080
- {ip}:8080?action=stream
-
The Ultimaker 3's display is managed by a different kind of computer (Olimex instead of Atmel (Arduino)), so this firmware probably isn't suitable for Ultimaker 3's right?
Maybe this is something that could be clarified in the introduction topic?
-
Nice diagram on this subject: https://www.gliffy.com/go/publish/5271448

I do most of my designs in FreeCAD. But it's certainly without it's issues.

The Ultimaker3 will run Linux on it's onboard computer. Are there any plans for an app / plugins system?
First ideas for plugins:
Automatically live stream every print to a (private) youtube video
See:
Automatic timelapse creation
Running an app on the onboard computer might mean we can make nicer timelapses, for example taking a picture at the start of every layer. I'm hoping this means the head is on a more consistent position.
Maybe the timelapses could be stored on the Memory stick?
Easy remote access using vpn
See: https://ultimaker.com/en/community/23534-remote-monitoring-control
These could be apps, published on a custom repository (ppa).

Yeah I'm already following Software and Firmware > General category, but that also means a lot of posts that are irrelevant, that's why I really like Discource's tags idea.
Another related issue is that it only reports: "Forum Cura and Marlin has a new topic (...)" and it doesn't link to the actual new topic. Probably because it doesn't add a notification per new topic. And then I'm always unsure about whether the topics on top are the latest topics or just the topics that had recent replies.
-
That sounds like an interesting and saver solution. Maybe even easier because you don't have to study the router's interface (of which there are many).
I hope someone will publish a tutorial on that, as I have no experience at all with vpn.
Ultimaker 3 suddenly no display and unresponsive button
in UltiMaker 3D printers
Posted · Edited by peteruithoven
Out of nowhere the display remains black when turning on my Ultimaker 3. The rotary button does not light up. Even after 4 minutes nothing happens. Clicking the rotary button does not trigger a sound.
I do notice when I turn it on a fan briefly spins and a red light turns on on the bottom near the LAN port.
I can't find it on my local network (It's connected over ethernet).
Nothing special happened before this happened. I've used the machine a few days before without any issues.
I didn't find any related topics on this forum.
I've never done this before, but I've removed the panels on the bottom too see whether there was something weird going on.
I notice that on the bigger PCB there is also a green light on, next to "NC".
I'm in contact with UltiMaker support, who advised reinstalling the firmware following Firmware recovery: Ultimaker 3.
I've tried this, but the leds don't respond as expected, not like the 3 possible states described in the manual.
At the beginning I'm turning on the Ultimaker, after ±9 seconds Led 1 blinks (but not really slowly). Led 2 and 3 just stay on, even after many more minutes. See video:
The display indicates that it's installing firmware, and that there are 2 minutes remaining, but even after 15 minutes there is no change. The display stills shows this message, led 1 is off, led 2 and 3 remain on. At least we know the display itself still works.
I tried redownloading the .img file, using a different micro SD card writer, I used a different micro SD card.
I'm running a Linux distro (Ubuntu derivative), so I couldn't use Win32 disk imager tool or the ApplePi-Baker app. I used Balena Etcher, which is a super common way to flash SD cards.
it's like it's stating with the firmware install, but doesn't finish and without going into an error mode where the leds would blink fast.
I have some software development and some electronics experience so I'm happy to do some more digging.
