almost there

so i am very close to understanding all f the settings in skein forge i believe. except, i have on and of problems with my z axis. i tried using limit to change the z axis speed to 2mm/s and it seems as though the z axis doesnt step enough as it should when im running apart. but if i jog it, it moves perfectly. does anyone have any suggestions? i have techzone monolithic electronics and am running repsnapper with sk40

also, it seems as though im stuck with the rectangular fill. i tried it once,and all my gcode has it now. even though it isnt checked in skeinforge

one more thing,when switching directions on the x axis( im jogging it with repsnapper) it doesnt step properlyimmediately. the belt tention is not too much though
