Printing at Angle, Skewed features - Help or ideas Bookmark Unfollow

Recommended Posts

Greetings,

(Software forum thinks it's a hardware issue, though I'm skeptical as we print test cylinders and nearly identical parts right afterward with no issue.)

I'm having a strange issue with one part printing features at an angle (skewed).

Here is an example of the part:

You can see how the features skew, and then straighten out. It's got a couple of us scratching our heads, an we think it may be a singularity in how the slicer handles the part.

Here's the mating part without any issues printed right before this:

I've checked the belts, etc. we even printed a cylinder the same height as the part to see if that would skew, and it did not. Time to come to the community for help.

Anyone have any ideas?

(Next I'm thinking we change nozzle size...)

Printing:

Ultimaker 2+ Ext, ABS, 0.6mm Nozzle, Bed temp 90C, Nozzle 260C, both Cura 15.4 and Cura 2.4, 100% infill, 100% support, 40mm/s speed.

Hi,

first - there is no logic in the forum software to categorize posts. Maybe another admin moved it here because this issue is so much in the "WTF?!?!?" realm that one is not sure where to categorize it :)

So did you slice with Cura 15.x and 2.x and you got the same skewed model? Then you can rule out the slicer.

Did you print other models just to see if the problem occurs at the same height? If yes, then it might be a hardware problem (loose pulleys if you didn't regard them already).

Another idea could be overheating stepper drivers which cause the motors to stutter and miss steps. I am not sure how the UM2 board handles this, but with a another board on another printer I have seen this behaviour.
