johnmclarren 0 Posted September 13, 2014 in Hello from Miami 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.

IRobertI 428 Posted September 13, 2014 in Hello from Miami 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. Share this post Link to post Share on other sites
