  1. Hi, We looked for EEPROM feedback and had no response... It seem that you're right, Olimex board or the EEPROM chip must be damaged. I hope the machine's warranty is still working ! So : A Build Plate height issue can be caused by an "identity crisis" from the printer, that's to say the machine doesn't know what type of hardware it is. Our conclusion (so far and in this particular case) is that this identity crisis itself is caused by a hardware damage on the Olimex board, concerning the EEPROM chip. Thanks a lot for your help ! I hope this printer will survive ✊
  2. Hi, I asked a friend with more skills than me for some help ✊ He acceed to the ssh server of the printer, logged in with ROOT and tried to launch Daid's command (seen above) to set the Hardware type ID to "9511". But, an error occured, with this message (last line) : python3 /ulti_installer/configure_eeprom.py 9511 Traceback (most recent call last): File "/ulti_installer/configure_eeprom.py", line 24, in <module> eeprom = EEPROM() File "/ulti_installer/eeprom.py", line 22, in __init__ self.__mac = binascii.hexlify(f.read(6)).decode('ascii') TimeoutError: [Errno 110] Connection timed out So the connection timed out, apparently… We were so close… and we can't figure out why did it happen.
  3. Okay, I think I understood what I have to do but I'm not really used to this kind of tricky business. Without instructions for Windows, I think I won't be able to solve this by my own… I have no idea of how I could connect to the ssh server. @tinkergnome the Hardware Type ID is 0, it must be related to the "unknown" type of the printer.
  4. Hi @tinkergnome, thank you for the quick answer! There is no obvious reason that could explain this identity crisis but few months of sleeping in a dark place… Every part comes from the original brand new box. The topic seems to talk about the same issue and I'm excited about trying @Daid 's solution : But I don't know how to send this command line to the printer… Is there a console on Cura ? Or do I have to install Python 3 ?
  5. Hello, I'm coming up to you about an issue I have with a UM3E that I tried to use after few months of inactivity. I installed the last firmware normally via the printer but, when I wanted to start a print, the UM3E failed during auto levelling step. Actually, the build plate stops at 10 centimeters from printheads, even if I try to level it manually. I tried every "normal" ways to solve the problem, user reboot, factory reboot, second setup of the firmware, via USB this time… nothing changed. The printer acts as if it was an UM3 not Extended, but it is… Every print I launch is considered too big for the printer, even the smallest thing. Maybe there is a conflict between Cura, where the printer is correctly set, and the firmware of the printer, set on the UM3 height instead of UM3E height. I really don't know how to check in the firmware and if it is possible to fix my UM3E… Please, help ! Build plate "raised"

  7. J'ai déjà réinstallé le firmware, depuis la machine et via USB. Le problème persiste, le plateau monte au maximum à 10cm des buses, même lorsque je veux régler manuellement le nivellement (je monte le plateau de quelques centimètres en tournant le curseur jusqu'à ce que ça me signale une erreur, comme si j'excédais les dimensions de la machine). Je vous le demande à nouveau, est-ce qu'il est possible d'accéder aux paramètres internes de la machine, pour voir si c'est à ce niveau que quelque chose cloche ? Merci
  8. Merci pour ta réponse. Oui, c'est effectivement ce que je me suis dit. Le problème c'est que le firmware s'installe et se met à jour par lui-même et qu'il n'existe pas, à ma connaissance, de firmware différent pour l'UM3 Extended. Sur Cura, les paramètres de la machine sont bien rentrés, avec une hauteur d'impression de 300mm : Est-ce que j'aurai raté une étape qui permet de paramétrer le type de machine en Extended ?
  9. Bonjour, J'ai récemment tenté de remettre en service une UM3E qui n'avait pas fonctionné depuis quelques mois. À l'allumage tout semblait bien se passer, le dernier firmware s'est installé sans souci, jusqu'à ce que j'essaye d'imprimer une petite pièce pour la forme. Au moment du nivellement automatique du plateau, celui-ci monte et s'arrête à 10cm des buses, ce qui mène à un échec de l'opération. J'ai tout essayé, réinitialisation avec paramètres d'usine, réinstallation des pièces comme au premier allumage, etc. Rien à faire, même lorsque je met le plateau en position haute, via le moniteur sur la machine, il s'arrête obstinément à 10cm des buses. Aussi chaque impression lancée, même la plus petite, est détectée comme étant hors format. J'en viens même à croire que la machine se prend pour une UM3 au lieu d'une UM3E, mais je ne sais pas comment m'y prendre pour vérifier ça... le plateau en "position haute" Je ne sais pas si l'attribut "unknown" est très bon signe non plus, ou si c'est normal. Si vous pouviez m'aider à refaire fonctionner cette jolie bécane...
