Posted · Ultimaker 2+ offsets build during print

Hi,

I am new to the Ultimaker 2+ and have never worked with 3D printers before.

I am printing with black PLA using the following standard specs:

Print Height 0.1mm

Print Speed 50 mm/s

Supplied glue distributed on the glass surface before printing

Cura 15.04.4

Updated firmware on printer

3D software is Rhinoceros 3D

I am experiencing some very annoying fails on 80-90% of my prints.

See attached photos.

It seems that the printers orientation is suddently shifting 1-2mm during the print and then 10 layers up switching back to the original orientation. As you see in the attached photos it is an identical fail that happens with identical pieces even though they were not printed at the same time.

Similar issues are evident in other larger geometries as well.

If anyone has an idea to what could be the issue it would be highly appreciated.

    Hi,

    I assume there is something up with the z-stage. Take a closer look at the long screw that moves the heated bed up/down. Maybe something got stuck in there. It might be a good idea to clean the screw and then apply a bit of the green grease that comes with the printer.

    Move the heated bed up/down a few times and listen/watch for any new clues.

    It seems to be the x y axis as the height of which the layer shifts is new for each new 3D model. But the same for identical models.. Thats why I initially thought it might be a software problem as it is linked to the specific geometry.

    I will try to check the pulleys.
