first layer issues

Ok -
im having issues printing my first layer - seems like its putting down too much material. ive tried in the "raft" settings to minimise it - still comes
out too thick - whats the best way to adjust it??
im printing in abs as well...
thanks!
Jeff

ok - so made a LOOONNGG ass print last night - the first 3 or so layers look too heavy - and any of the fully solid layers do too. (pictured)
However, the perimeters as well as the "gapped fill" layers look awesome!! this excess seems to only happen on the fully filled layers.
so how can I turn that down only without affecting the other stuff thats good?
Im thinking in fill?? but which option is the right one to tweak?
Thanks!

Your flowrate is too high. How you adjust it depends on what software you're using to slice the STL files.

ok - im using sfact - havent had good luck with slicer.
now if my overall flowrate is too high then how come my perimeters and non-filled areas look great?
or is it just my infil flowrate?
so - where to adjust that then?
thanks
Jeff

Your perimeters and sparse infill come out nice because the extra plastic has somewhere to go, so it doesn't build up. You need to adjust your extruder steps per mm so that your extruder pulls in exactly 1 mm of filament when you tell it to move 1 mm.

yup - thats been done and is correct.....
im sure its a software/skiening issue that i dont have right...

Also -
whats a good test to do for this problem? I know it wont show up in the perimeter test..
im just trying to figure out how to balance the infill without changing the perimeter - ive messed around with some settings and the fill gets better but the perimeter suffers...

If you're using Skeinforge 041 and later, you have to set the flow rate equal to the feed rate in the Speed tab. Start by setting both of them to 20 mm/s.
