Very strange behaviour, perimeter tracking

Recommended Posts

Posted · Very strange behaviour, perimeter tracking

Hi guys,

Im using Cura 15.02.1, and have been for some time now. However, a strange problem has recently developed. Whenever I print a part not, on each layer rather than taking the most direct route to the start point of the next layer, it tracks around (on top of) the perimeter. It ruining the prints, as a little plastic is dragging every time it does this. Is this a settings issue?

Thanks,

You have probably got Combing turned on, - first item in Expert Settings.

I forgot to close this, just after I posted the question I found the combing feature. I was a little surprised that with combing off, the print time increases by 2 hours. I'd expect it to go the other way as the print head it taking to most direct routes. Is this normal?

Also, how about z hop, is it a feature worth using? When combined with combing, (or combing without perimeter), does it improve print quality and stringing?

    • "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.
