Hi folks. I've searched the wisdom that is google and am still at a loss.
I'm printing with a Prusa iv3 10".
I have calibrated and adjusted my extruder
.40 nozzle printing at 194 on a bed heated to 64 on glass
I've used different slicers, and changed the settings I understand, and a few I don't. No matter what I get these results. Basically, my layers are not solid, they end up being a screen.
Here's a picture of the 2nd or 3rd layer of a print last night:


During this print I used the ramps board to up the flow to 120 (120%??) and I had evidence of over extrusion. That makes me think I am extruding the proper amount of filament.
This print was .15 layer height.
Do you need any more info? Do you have any ideas?
Thanks for reading.
