    Complete heated bed kit for Ultimaker

    in Third party products & modifications

    Posted

    Hi Drayson,

    I recently bought the Jason Wu's kit. (Very efficient service, by the way!)

    I quickly decided that I should find a nicer replacement for the relay board.

    I designed a small board to easily link the UM1 electronics to the Heated bed. It's 100% solid state. No relay!

    And for the peace of mind, it's optocoupled so there is no electrical link between the Ultimaker electronics and the Heated bed power supply.

    I just received the PCBs and I'll quickly assemble a couple of them...

    If some of you find this interesting, I can share more information on this...

    Hotend V2 drawings

    in Third party products & modifications

    Hi David,

    Thanks for the link.

    Regardig the PEEK insulator, it's fine for me.

    If there is no such document for the Teflon insulator, I'll have to take accurate measurements on a fairly soft material....

    It the field of keeping the Utlimaker an open-source design, shouldn't those new hotend's standard components be properly documented anyway?

    Hotend V2 drawings

    in Third party products & modifications

    Hello all!

    I am looking for the drawings for the components of the Hotend V2.

    Mainly the PEEK insulator, the PTFE insulator and eventually the brass parts.

    I recently had to replace the PEEK insulator as it got deformed. (Although I only print PLA at 220°C max) and the Teflon insulator also got deformed.

    I want to machine a peek insulator that should be a bit stronger than the molded version.

    Any idea of where I can find the drawings of those parts?

    Arduino - Panne de la commande de l'extrudeur

    in Français

    Posted

    Hello,

    As tu touché, pas le passé le réglage de la limite de courant sur le module de commande du moteur? (la petite carte avec un petit dissipateur)

    Vérifies aussi si la carte est bien dans le "couloir" de ventilation. Si tu as forcé sur le moteur, la carte a pu chauffer plus que d'habitude et si le refroidissement n'était pas nickel, tu as peut être griller la carte....

    Sinon, tu peux affiner ton diagnostic en echangeant 2 cartes de commande des pas à pas et voir si ton problème se déplace avec la carte. Si c'est le cas, tu es bon pour acheter une carte de rechange.

    How I'm air cooling the extruder motor

    in Third party products & modifications

    Posted

    Hello,

    I have a similar setup:

    https://plus.google.com/u/0/photos?pid=5915739618682206690&oid=112842179594188428003

    It uses a 24V fan directly on on of the power ports of the Ultimaker's board. Then it runs very quietly and is enough to keep the extruder motor cool.

    The mount is made with a zip tie and 2 3mm holes on the back of the machine and some scotch mount tape to avoid vibrations.

    Dual extrusion !

    Hello Hugo,

    Tu as plus intérêt à "investir" dans un nouveau tube en teflon et les maintiens associés.

    J'ai changé le "bowden tube" pour un autre plus large à l'intérieur qui ne bloque plus les filaments "low cost" et coté entrainement j'utilise un raccord rapide de chez SMC qui tient le tube à merveille et coté tête je suis parti du clamp de Owen que j'ai amélioré avec un raccord fileté.

    Quelques centaines d'heures d'impression plus tard : Rien d'a bougé.

    Cura 13.06.4 and heated bed support

    in UltiMaker Cura

    Posted

    Hello!

    When installing Cura 13.06.4, at some point the installer asks if the Utimaker is equiped with a heated build platform.

    If I answer "Yes", what are the heated platform setup that will be used? (Model of the temperature sensor, type of control of the bed's heating plate...)

    Best regards and "NICE JOB" this new Cura!

    peek problem

    in Third party products & modifications

    Posted

    Hello!

    In similar situation, I cleaned the peek part by dipping it in Dichloromethane (it works also with acetone, but it's less efficient). Out of the dip, you can finish the cleaning with a toothpick as PLA/ABS soften in the solvant while PEEK is insensitive to it.
