  1. Wegen einer Neuorientierung benötige ich Platz und trenne mich schweren Herzens von ein paar Ultimaker Druckern.

     

    • Ultimaker 3
    • Ultimaker 2+Connect
    • Ultimaker S3
    • Ultimaker S5 mit Airmanager
    • Ultimaker 2Go

     

    Alle Drucker sind in einem 1A Zustand, wurden regelmäßig gewartet und haben auch eine Menge Zubehör, wie Printcores, Filafarm Switchplates, zusätzliche Glasplatten etc. Es sind auch noch tonnenweise Filamente vorhanden.

     

    Bei Interesse bitte via PM melden.

    Die Drucker werden nicht verschickt und müssten selbst abgeholt werden. Standort Wien bzw. 3001 Mauerbach.

    I was wondering whether anybody is experiencing the problem where the printer would lose connection to Digital factory permanently.  In network settings I have an IP address, but the "connect to digital factory" button is greyed out and a message is indicating that I require a network connection.

     

    Going back to network settings I can clearly see the IP address.  Further to this, the WiFi icon on the printer clearly indicates it is connected.  I have also tried connecting to LAN cable directly, but the same problem persists.  

     

    No solution, but I have the same problem with my S5. The S3 and the S5 are in the same room, same access point. S3 is stable, but the S5 gets disconnected after some time. It is not a local network issue, I can SSH and ping the printer. But it is disconnected in DF. A power cycle helps to bring it back online for some time. Very annoying...

    My current workaround is that I have instructed all the usual suspects to never ever hit that "upgrade" button again.

    Yes, that's a weak point. You could try, depending on your infrastructure, that you block the outgoing connection to the UM update server/destination on your firewall. Then you can be sure nobody can update the printer by accident.

    If any of these are trivial to implement in UltiTuner, feel free to add them to your idea list!

     

    sorry for my late reply

    Your ideas are great, many useful features, but I fear it will be hard to implement these things. I mean everything is doable, but it would be needed to dive very deep into the UM code to change the behavior. The problem is, when a new firmware version is release you (me) can start from the beginning in worst case. 

     

    Personally I don't understand why UM don't listen more to their users and implement functions which are helpful for the operators. i.e. turn off the active leveling from the settings menu, if a user don't want it. 

     

    The digital factory cloud is also not for everyone, some don't want to send their files in the cloud and want to keep it internally. Others in bigger companies don't even have interner access from their production department, so there are many cases where a local only installation is needed and would make sense. Sure you can still access your printer from the local network, but as far as I heard some functionality was gone with one of the latest fw updates.

  5. PLA+ is just a name from Sunlu, other venders call it ToughPLA or PolyMax,.....

    It is much stronger/stiffer than normal PLA, not so brittle. It can be, depends on the vendor, stronger than ABS, but it still has the same low heat resistance as normal PLA. 

     

    Personally I like this kind of PLA, it strong for most cases where I don't need a higher heat resistance and it prints easy like normal PLA. Give it a try....

  6. The screw is not the reason, even if it helps sometime. I struggled with the same problem and tried nearly everything, nothing really helped. I turned off the leveling at all to be able to print with my S3. 

     

    The final solution was to replace the print head PCB, not the sensor board. After I have replaced the PCB, I never got an error again.

  7. The printer knows the material from its GUID number, so duplicate is the right way, because you want to use a generic filament (a brand which is unknown for the UM printer) and set some settings, specific for this filament. 

     

    I never tried it, but I guess when you use Create New, then you also get a new/unkown GUID number for the filament. 

     

    But there were a lot of changes since I wrote the post. i.e. you can now also transfer profiles from Cura to the printer, so maybe also a new filament would work now in some cases. But I never tried it, so I have no experiences. I read some complains in the past, the the transfer is sometimes working, sometimes not.  Maybe it is fixed already, but I don't know. I don't use profiles at all, I just use the default generic PLA for nearly all my PLA filaments (also Filamentum)

    SSH'ing and using gcode commands is exactly what I wouldn't want users to have to do haha...not the most intuitive or easiest for probably the vast majority of people. If Ultituner had a method to just jog the head left, right, up/down, and readout the current position that would be amazing.

     

    @leonhart88

    Also UltiTuner is using SSH to communicate with the printer, so the user has to enable the developer mode first on the printer, then UltiTuner can connect.

     

    The tool is very simple it basically just sends different shell commands via ssh to the printer. Some modify a file (change a parameter) or triggers a DBUS message. You can check the code if you want, it is open source on GitHub. 

     

    Also feel free to fork it or contribute the changes you need. 

  9. @leonhart88 I think it will be a lot of work to implement it. You need functions to move the head, but that would be much more user friendly when it is implemented into the printers interface itself. Via the ssh connection you can use gcode commands to move the head, but if it is easy to use for an user - I don't know.

     

    The other part is to store the values manually - I also guess that should be possible, but no idea how it is handled currently from the firmware and where I could find the functions. 

     

    The whole firmware (most parts of it) is python code, so one could reverse engineer the needed parts and find out what is possible. But that's a lot of work, the code is not easy to understand, not because it is not commented or well structured, no absolutely not, but it is hard when you have no idea how the whole thing works with all these parts. So you have to go from one function to the next one, to understand how it could work.

     

    The biggest problem with such hacks, includes also the current functions of Ultituner is, that with the next bigger firmware update, everything could be different and these things are not working anymore. Then you can start from the beginning with the reverse engineering.

  10. Hi Pieter

    first of all, I don't work for Ultimaker, so all my knowledge is debugging, "reverse engineering" and try and error 🙂 

     

    There are postings here in the forum that you can attach a USB webcam to the USB port and that it should work. (unofficial and not supported) You get an additional port number which is 1 higher than the built-in webcam. It seems it depends on the webcam you are using. I tried a Logitech webcam, but it was not working.

     

    Beside that, I don't have any additional information about the webcam and I think there is also no manual for that, maybe UM internal, but nothing which is available for the public.

  11. Hi,

    theoretically it should be possible the get somehow the error messages from the bus, but I don't know a possibility out of my head. I can take a look at it if I find something to fetch the current error.

     

    Just for interest, Digital Factory or Cura itself should also show the error message, is that not feasible to your workflow?
