Nozzle marks issues...

[mrdindon 0]

Dunno if anyone can help me but here is my problem:
Flat printed surfaces show nozzle lines but only starting at layer 2. Walls top are ok, Layer 1 also.
If I lower my bed, I start having adhesion issues.
Extruder e-steps are calibrated as shown in picture (100steps = 10cm)

 

The only way I am able to have flat surfaces without any nozzle lines is by lowering the Flow in Cura down to below 70.
I was wondering if this is normal or if there was any other settings I should look for ...

Using Cura 4.6.1 with an Ender3 Pro, PLA 1.75. (See print details below)

Your initial layer height is .2mm and the "Initial Layer Line Width: 150".  Notice that most of the rest of the line widths are the same as the nozzle diameter at .4mm.  (The other odd one is skirt line width at .2.)

The flow at 100% and E-steps near 100 make good sense.  I think the machine may be trying to compensate for that big line width number on the first layer and putting down too much plastic.  Then with the very small layer height of .08mm, there is nowhere  for the plastic to go and the 2nd (and probably a few more) layers look like they are over-extruding.  What they are really doing is dealing with the heavy first layer.

I suggest you change the Initial Layer Line Width to .4 and the Skirt Line Width to .4.  Then try printing it again.
