hi guys, i have been using s3d every day for over a year now and try to help out on their forum best i can. i can answer many questions but since i dont have a makerbot or one of the clones i dont have much input on things directly related to that. same goes with dual extrusion. other than those things though i know the software really well.

as already mentiond the whole starting sequence is done in the starting gcode section. the default sequence is SUPPOSED to purge the nozzle and use the edge of the bed to scrape the string off the nozzle. works well for me but i am using abs or pet all the time.
