Hello from Miami

Recommended Posts

Received my UM2 a few days ago and have been absolutely loving it. It's quiet, fast and precise. I did have a few hurdles, first I had a heat bed issue when I first turned it on requiring me to take the build plate apart where I found a loose wire for the heat bed. After that I had an issue with the extruder, I noticed filament was not coming from the tip no matter how much I ran the extruder. Turns out the gear on the rear feeder ground into the filament. I retracted it, cut it off and fed it back and it has worked perfectly since.

I do have one question, I have run it over night once. I know it turns off the bed and hot end when it finishes and I have it set to turn lights off, but is it ok for it to stay on? It sounds like it keeps fans on even when not running.

Yes, you can leave it running. The fan you hear is the so called "third fan", a tiny fan that is mounted at the rear of the print head that always runs whenever the machine is turned on. I guess you'll take a few hours off the total life of the fan but other than that it shouldn't be a problem.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
