I got most of the problems addressed, now extruder is properly set on/off. Also tuning the M227 values to P200 S200 (works fine on my Bowden extruder) seem to have fixed oozing problem. Current Slic3r settings add wipe moves, not sure if those help.

Only problem now is the filament feed rate, perimeters seem to get more material versus solids. Currently i'm calculating feed rate by reading the head speed while extruding and multiplying that value with 0.015. Tuning that value will help with solids, but as it effects every type of path, perimeters will get also more material -> still uneven.
Better solution might be to read the actual extrusion length that Slic3r puts to each move and calculate feed rate from that value.

Did a test print (Torture_test.stl) and it's looking quite good, apart from the solids. More tuning needed...
