Dash lines on the top layer

Recommended Posts


I'm still learning with the S5 printer.


Here two pictures of two parts (PCBs mockups); as one can see there are some dash lines on the top, even some smaller solid lines. 


Where do they come from?


I am using old PLA from a Prusa printer. The nozzle is 0.4AA, layer height 0.2 and I use the default speeds, temperature that Cura 3.6 proposes

these lines are from travel moves over the skin.

You can configure the behavior with setting "Combing" to "not in skin", then when printing the skin, the head will avoid the skin areas.

Interesting as I have never used combing. Looking at your pic I suspect your retraction settings would benefit from a tune as a complementary or alternative option. I use 5.5mm for PLA/PHA and 6.5mm for  nGen. with a 0.4mm nozzle and running cool

I will try these retraction options. I'm using pretty much the defaults from Cura, I understand they are optimized for the S5.


Honestly I'm a bit surprised about this, because it makes the printouts look ugly with the standard settings

    • "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.
