unccheezy 1 Posted January 24, 2017 in Power ON sequence is confusing I noticed this on our UM3. When I power it on. There is a noise that instantly starts then stops a second later (sounds like a fan kicking on/off) then the screen comes on like 10 seconds later. I thought my machine was broken. Took me a while to realize I just needed to wait. Share this post Link to post Share on other sites
DidierKlein 635 Posted January 25, 2017 in Power ON sequence is confusing Yes it's a bit weird but this is due to the new electronic board that needs to boot up and take a bit more time than starting an Ultimaker 2 Share this post Link to post Share on other sites
