  1. @gr5 I work with college students who are not always 100% trained on these machines like you and I probably are. Plus with 18 UM3s and 6 UMS5s I see some of the small statistics like how often head floods pop up. I'll be sure to watch your video still! I'm always training my staff to look out for things like when parts are peeling up or underextrusion so maybe I'll find more training material for them. The magnets were my cause at least 3 times. I bent the frame of the head back into place so they had a stronger grip which fixed the issue. Also stuff like this exists for that reason https://www.thingiverse.com/thing:2658960
  2. I've had this blobbing happen to me a few times now. Typically, the extruded filament didn't stick to the bed well enough, the printer was still extruding and filament had nowhere to go but up (into the head). I usually clean this very slowly by heating the head up, picking away any melted plastic I can get to, then taking apart the head and finally using a heat gun to heat up the plastic to peel it off. It takes a lot of patience to do and have a good printcore afterwards.
  3. Downloaded and installed without a hitch! I noticed two things immediately. 1. Opening a Cura Project 3mf file from <4.0 does not inherit any of the project's settings. I had to reinstall 3.6 to get a bunch of settings to show up that I had tweaked iteratively for a project. 2. I can't seem to slice... I've had errors like this before and typically changing the Prime Tower X and Y location fixes it. But the Extruder Prime X Position is not available for me to change/fix.I feel like this is buggy behavior, but please correct me if I'm wrong. Edit: Well, I haven't come across the issues described above again, so I'll consider them flukes! I forgot about the setting to change how Cura Projects open underneath Preferences...
  4. @SandervG I'm having trouble with the HTTPS certificate of accounts.ultimaker.com as well as signing into the forums on a new computer. Every time I go to sign into the forums I get this message. Tried using Chrome and Firefox. Cleared the cookies and tried again, still happens. I'm currently remote-desktoping home to an already signed in session to post this.
  5. Because I just guessed off the top of my head ¯\_(ツ)_/¯
  6. We often print small parts, less than 2 hours, on the S5s because they have a lower failure rate than the UM3s. Mostly because of the filament sensor I think. I think it's overall a better experience using the S5s. It totally depends on the slicer settings. The F400 (the model I have versus the F410) prints faster by default at around 100mm/s while the Ultimakers default to much slower around 60-70mm/s. When we use the F3s, we print XL models so they take a really long time anyways. But a benchy takes around an hour and a half on each printer.
  7. Hey there. I would use the S5 without a doubt. If you need consistently large print volume in your prints, get the Fusion3, but the UMS5 has plenty of build volume for most prints we run through. I like how many UM3s can fit all together and we rarely use the Fusion3 anymore due to ease of switching printers in Cura versus using Simplify3D for the F3. And I suppose, even if you only have consistently small prints, I would probably still use the S5 since it's the newest bestest product.
  8. Hey @geert_2! The mats I ended up buying were these plain 1/2" thick EVA foam mats. All of the printers are on top of them now. They certainly made an improvement of tiny vibrations of other printers over having nothing there. Here's a picture I just took after I moved the printer from where it normally sits. My only issue now is the fixtures that all of the printers sit on need to be updated to more industrial, sturdy materials. After that the foam mats should have a greater effect on the vibration dampening since the fixtures will not be moving around as much, if any. Cork sounds like it would be an good choice. In my situation, getting around 100 sq ft of the stuff might prove expensive. The EVA foam mats were like $100 or something, I've slept since then.
  9. I like your thought process here! Checking the Z position would be very helpful. Perhaps I can make a second script to "run once" and double check the values during a test print (calibration cube type thing).
  10. Yes, I think I know what's going on. It's the (x,y) position of the head in the corner there. I mean the physical position of where the Ultimaker head parks, not the tall 1x1mm dummy object. I wonder if the coordinates are exactly the same as mine or if something like firmware or Cura versions change it. Here's how to test it, During the first couple of layers of your print, run this python3 test.py: https://github.com/starbuck93/um3timelapse/blob/master/test.py after editing IP_ADDRESS in the script to be the IP address of your printer. While the (benchy, calibration cube, whatever) print is running like you have set up in the screenshot, the test.py script will output X and Y coordinates of the head. When the head is parked in the corner waiting for PrintCore 1 or 2 to reach the correct temperature to resume printing, check what the X and Y coordinates are. When I was testing, I saw the same coordinate set around 3 times in a row. After that, in timelapse.py, go edit the location_check function (link to github) to have the X and Y coordinates you discovered with the test.py script. For UM3 I found test.py output x213 y189 and I also saw x209.375 y193.0 several times too. I ended up with 213,189 in mine, but yours could be different.
  11. Yes, I believe it does. It sounds like you might be using windows? You can either copy the ffmpeg.exe to the same folder as timelapse.py you can edit timelapse.py to include the full path to ffmpeg around line 126 starting with ffmpegcmd ffmpegcmd = "B?path\to\ffmpeg.exe ...rest of the line stays the same" Or you can add ffmpeg to your PATH. (something like this https://www.java.com/en/download/help/path.xml)
  12. Hey @PaulMiles! Here's the information in your error message that's important: ModuleNotFoundError: No module named 'requests' To fix that, I'd use python-pip to install the package called requests like this pip install requests or "pip3" if just plain "pip" doesn't work for some reason. pip3 is the python3 specific version.
  13. The latest code is on GitHub here https://github.com/starbuck93/um3timelapse. Use the "Clone or Download" green button and then click "Download ZIP". Or "Clone" it if you're so inclined! Go ahead and unzip it where you downloaded it, probably in the Downloads folder, or your Desktop or wherever. After that, go to the unzipped folder, and at this point it depends on your operating system. For Windows I'd say to run `cmd` and then all you'd do is `cd` to the unzipped folder and run `python3 timelapse.py 0.0.0.0 1 video.mkv` and let it run! It handles the frames automatically so you'll never see a folder full of pictures and the video is saved in the same folder you run the python script in. That would be really cool. I suspect there would have to be support for saving to the USB stick as there is not much onboard storage for these types of things!
  14. @cloakfiend yep! It uses the built-in API to access the required information including the camera. The original code just has a time delay for when it takes pictures to build the timelapse, but I wanted the head to move out of the way too. So I looked at the X and Y position when the printer changes printcores and does its thing and told my forked code to watch for that exact position. Therefore whenever the printcores change, we take a picture and build a timelapse! Setting it up to work on any given computer should be fairly easy. I'm using a Linux server (Raspberry Pi) so it was not hard for me to set up. All you need to do is install Python 3 (latest) and install ffmpeg for your system. Then run the script on the command line with the IP address of the printer, the number of seconds of postroll you want (probably 1) and the output file like `timelapse_1.mkv` or something.
  15. The print time is increased by the nozzle switching. I increased an 8.5 hour print to 9 hours by adding the ghost tower for extruder 2 in the corner. I feel that is an acceptable amount of time for the reward. I haven't had any nozzle clogs yet but I've only done this a handful of times already. I suspect you're correct and that the 2nd nozzle will clog after a little bit of time doing this. Also, I've added support for the Ultimaker S5 as well and I'm testing that right now with the print I mentioned above!
