Top surface quality issue

Hi everyone!

It's been a year or so since I have my Mendel90 and I printed many stuff in PLA/ABS/Ninjaflex without any really big issue. It's really a nice printer.

I'm using Skeinforge and change the parameter by fallowing the advince in the manual of the M90, however, I have a little problem with the quality of the final layer surface.
I don't have this issue when I print with a 0,3mm or 0,2mm layer height, but with a 0,25mm, W/H ratio of 2,08, perimeter flow rate of 0.896826 and nozzle of 0,4mm.
The material is natural ABS printed at 265°C.

The little part of the T is alright, but the infill of the long part is quite spaced.
(The bits of plastics at the bottom is due to the brim)

Do you have any ideo of what parameter might help?
Thanks!

Your image does not show the infill clearly enough. I can just see steps due to the slope of the long element but not infill detail.

Haha, thanks Neil!

It look like the real issue is with my brain
Indeed, I was talking about the steps...obiously caused by the slope…

Sorry, guess I need some sleep...

have you tried slicing it in Cura or Slic3r?

Drag the gcode into pronterface and you can see how it will print.

I didn't visualize the g-code before…my bad, but indeed, by looking at the slice in Cura or even with skeinlayer, it look like it printed like it should have.

It was a mistake on my part,
