Inconsistent Layers

[Daniel.Ortiz 0]

I’ve been having issues with my Ultimaker 3, as shows in the pictures, some layers print inconsistently and there is a gap in between some of the layers. I’ve attached the settings. 

 

NOTE: The speed was actually 20 mm/s for both Infil and Print

 

i also noticed the infill has gaps in between layers as wel. Any ideas on what might be wrong or how to fix this?

Your settings do not seem to reflect the model shown. Apart from a setting of 70mm/s when you say 20mm/s, the base of the boat has no bottom but your settings say top/bottom thickness 2mm - all very strange. Quite possibly problem is due to under-extrusion but difficult to say as you have not quoted extruder temp. Otherwsie is could be a problem with your feed system/filament - maybe the filament is poor quality with uneven thickness which is causing it to stick inside the Bowden tube

There was an issue with the motor on the back and it just needed to be tightened a little more.

Thanks for you help!
