Layer shift in prints on Ultimaker 2 +

Recommended Posts

Hello All,

I have been using my Ultimaker 2+ for 10 months now.

No problem. Excellent prints.

But in last two days I am getting an issue of Layer shift.

I am sharing some images with you all to help me our with the problem.

I have tightened all the pulleys . Even the small ones.

I really need help because it was working absolutely fine until yesterday

Tighten them MUCH harder. If you use a hex driver (like a screwdriver) you should be afraid the tool will break. It should twist slightly. If you use an L shaped tool your fingers should hurt for a few minutes after. REALLY TIGHT. You probably only need to get the 2 on the short belts of the slipping axis - not all 11 pulleys. I can't tell which axis is slipping because you already removed the part from the printer.

There's a very small possibility that your stepper drivers overheat and shut off for a half second occasionally also. But I strongly doubt that. You would likely have issues with the Z axis long before X or Y. This is 98% odds that it's a pulley set-screw.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
