Yup, maybe that's the issue. I've always used active leveling. Now, I'll calibrate Z axis once again, and do the manual leveling for the first time. Maybe the springs and the screws was the problem. Thank you for the reply!

Hello everyone, I'm learning to 3D print with my U3+ and last night, while Ultimaker was printing 14-15h part, there was an accident. As you can see on the picture, first hours was ok, the element is set in place, support is printed etc. But at some point something happened and whole plate with print on it moved (I closed the metal holders before I started to print, I'm sure). I think there could be problem with leveling at some point - nozzle hit the print, moved it with the plate, and continued printing. This happened to me second time, so I don't think the cause was something from the outside. Do you have any ideas? I've tried to look in FAQs but there's no issues like that. Here's the image:

Hi there, I'm learning 3D print with my U3+ and today, while I was printing 8-9h part, PVA support material ended (2nd core). Is it safe to continue printing without material in core/nozzle? I've reduced temperature by 25 degrees (I can't reduce it more), and changed the flow to the minimum value. I don't want to stop print because support is no longer needed (even if Cura created program with the support to the very end). What do you think about heating up core without material inside?
