Question: Is this a Newbie mistake or Cura glitch.

Recommended Posts


I use the newest version of Cura (2.1.2) to slice a model.

My printer (a modefied Print Rite, all vibrations removed) is a makerbot replicator clone and to print I use Repetier-host v1.6.2.

When I load the sliced file in Repetier i see a representation of the model.

I have printed this model and I noticed a strange thing.

The representation shows lines and faces and not the whole model. (photo A)


However, on the print those lines and faces show up as print faults in the otherwise very smooth print.(photo B)


My question is : What am I looking for? Is it a glitch in Cura or a setting I haven't realised.

Those same lines also show up in representations in other software (mattercontrol v1.4) (photo C), when I load the G-code,so they are written in the G-code by Cura.


I hope somebody knows the answer.

Here some things to check (if it were me):

Is it a true solid? Check it in Meshmixer or Sketchup's Solid Inspector.

How thick are the walls? Are they as thin or thinner that your print head nozzle?

If you turn on X-Ray mode in Cura, do you see any Red areas? These indicate issues with your model.

Do you have another slicer to try? That might help narrow down the issue.

Hope this helps.

I'm not sure what's going on here but usually slowing it way down fixes all kinds of problems because that way there is less pressure in the head. Try 25mm/sec next time you see this (just slow it down in the tune menu) to see if that fixes everything. It could possibly be a cura bug - not sure.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
