Circular Gaps

Tue May 30, 2017 10:37 pm

I am trying to figureout what is causing these gaps (and similar in many other prints with circles), and how to eliminate them:

I have attached a factory file. Does anyone know what is causing this?

Take a look at this thread: viewtopic.php?f=9&t=7542&p=32493&hilit=gaps#p32493

Is this the same question??? If so, the "gaps" are where coasting is taking place. If set right, there will be no gaps in the printed model!

Yeah it is the coasting.
4,5mm Retraction distance looks very high in my optinion. I'm more likely using 0.6-1.0mm. But maybe your printer (bowden?) does need this high amount
