how is D9 gcode controlled ? i thought D9 was for a second extruder not a fan? also the 2 pin connection mentioned is for PS-on ability isnt it? if so, how is it able to be used for a fan location?by 09zx-6r - RAMPS Electronics

have you tried to adjust your stepper settings? i had the similar issue and realized that the Z axis screw i used isnt what nophead uses but it is adjustable... when i figured that out i was able to increase the steps 200 at a time till the distance traveled matches what i tell it in pronterface... then send a command M114 to find out where the Z axis really is..if still off, keep adjusting...yby 09zx-6r - Mendel90
