[Bottom Layer Very Rough]

Hi Greg,  

 

I was tracking until your last line.  I do not know anything about calibrating the E-Steps.  Can you shed some light on this?

 

Thanks, BK

[Bottom Layer Very Rough]

Good evening,

 

I am new to Cura and new to the forum as well. 

 

I have a problem with the bottom (first) layer.  The direction of the extruder is perpendicular to the length of the part.  This looks rough and very busy.  There are "crinkled worms" in a repeating pattern all along this layer as well.  I don't know if they are being formed by the layers above or where.  I used a raft which printed very smoothly.  I am trying to figure out how to make the first layer print parallel to the length of the part.  In order to make the part fit on the print bed, I need to rotate them corner to corner.  I have discovered this has an effect on the pattern of the first (and all) layers.  Because, when I make the parts parallel to the print bed, the first layer prints at approx. 45 deg.  I do not think other slicers I have worked with do this.  I am hoping it is a setting!  I am using matte black PLA printing at 210C and 50d build plate temp.  The part is ¾” square and 11.5” long.

I hope the Cura.3mf file and photos are helpful.  If someone needs more, please let me know!  I really appreciate your help.
