[UM3 Small shift after only 15 prints?]

Hi everyone 🙂

I have recently bought a UM3 (1 week ago) and it have made around 15 perfect prints, of the same print.

When it came to the last print, it made a shift, I thought it was just a 1 time issue, i then made 1 more print

but it really made a bad print. I have seached the forum for all the adwise, and I have checked/lubricated everything, 

just wondering if you have any good inputs after looking at my pictures?

[Ultimaker 3 - Print start warping 4 hours into print]

Hi guys,

 

Could some one eplain me why my prints start to warp severeal hours into to printing???

The beginning it was fine, no warp at all. now i see some corners starts to bend.

I print with Ultimakers black PC.

 

The lid of my box was completely closed, now I have opened it a little bit, to let som of the warm air out, fearing

that it was because it was too hot inside??

[Ultimaker 3 - Nozzle dirty/First layer not "smooth"]

Hi everyone.

 

The company i work in recently bought a Ultimaker 3, since we are going to make some End-Use holder for a

spirit bargun, I was told that the Ultimaker was the best 3D printer to go for, so we didnt need to use too much time

on setup.. I had just struggles abit, making the print "perfect"

 

Yesterday i finnally started up to print 6 pcs at the same time, but 30 min into the print, 1 of the units start to 

warp in the corner. 

I then restarted the process and instead of printing 6 i set it to print 3.

It then started again, but this time i noticed that the first layer wasnt really smooth, how can this be? 

I have attached a picture of the layer, the nozzle of the Printer is covered in black filament...

 

I am printing these with Ultimaker PC filament.

Regards Nicolai
