E3D-v5 an UM Original

Recommended Posts

Hallo UM-Gemeinde,

leider bin ich beim Umbau des UM Hotends an meine Grenzen gestoßen. An sich würde der Drucker laufen (Erhitzen mit richtigen Temperaturen, manuelles Herausschieben des Filamentes). Aber jetzt das Problem:

Wo schließe ich den Lüfter vom Hotend an? Ich finde da keine Anleitungen im Internet und/oder sonstige Informationen (Baupläne o.ä.). Ein Bekannter, der auch mit einem Ultimaker arbeitet (komplett Original) sagt, ich soll einfach die Kabel vom Lüfter an die vom Hauptplatinenlüfter anlöten. Wirklich?

Was wäre jetzt der beste Weg, den Lüfter am Hotend zum Laufen zu bringen?

Der Lüfter vom Original läuft mit 24V Gleichstrom, genauso wie der Lüfter vom HotEnd - der Elektronikanschluss für den Platinenlüfter speist aber nur 19V aus.

Ich verwende den Ultimaker mit 1 Extruder, ohne Heizbett und (noch) mit originaler Firmware. Mein Board ist die 1.5.7er-Version.

Danke im Voraus!

I have connected it with the spare wires of the second hotend for dual extrusion. I connect the other end to a separate 12V power supply (the fan is 12v in my case) which is operational even when I power off the machine. I let it run until the hotend (v6 in my case) is cooled below 50 degrees).

 

My setup is 24V power which power everything

24V->19V dc dc converter for the umo power

24V->12V dc dc converter for 12V fans

24V heated bed

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
