Good speeds?

[Geoff]

I generally print with one stepper removed and almost always at .2mm layer height. I am never successful at printing .3mm layers and they always look like wicker basket crap anyway.

My standard speed with S3D is 6000mm/m feedrate and 7200 travel. This equates to 100mm/s feed rate and 120 travel. First layer is at 60% speed.

Any trick to getting it to extrude properly at that rate? if I go that fast, it will miss lines in the solid infill, the walls seem ok - but the infill basically has gaps in it every few lines. The absolute fastest I can seem to go without screwing with acceleration is about 85ms
