  1. I have an Ultimaker 3. I have a relay that can be triggered with 5-12V to control a 120V outlet, into which I've plugged my exhaust fan. I've got the Enclosure Fan plugin loaded in Cura, and now I'm trying to learn where to pull a low voltage trigger signal from. Any ideas?
  2. That's perfect, I had totally missed this. Clicking the checkmark (which is blue if the settings are synced, gray otherwise) and then clicking inside the settings rectangle causes them to sync. I totally missed that - there's no indication that's what it's for.
  3. You may want to use a tool like 'curl' that handles more of this for you? https://ec.haxx.se/http-auth.html
  4. I am connected to the same network. I am using whatever version was out just a week ago. What does the Sync button look like and where is it located?
  5. Question about the Enclosure Fan plugin mode mentioned: when this is installed and enabled, how do you trigger an external fan electrically? I have a relay that expects a 12V signal in order to turn on power to my fan. Where do I hook this up?
  6. I am a new user of an Ultimaker 3, and I have what is probably a simple question. I've loaded Ultimaker-brand RFID tagged materials on the printer, and the printer OLED display shows the correct type for each. When I work in Cura, though, the Extruder 1/2 settings let me pick any material, and I don't know how to get them to "reset" to the ones actually detected on the machine. Is there a way to remotely see what the UM3 has currently detected on the spool, and also see what type of print core is loaded in each extruder slot? My printer is located far from my workstatio
