Step 4.
Adjust the two back levelling screws.
Move the setup block and try to slide the block
and card under the nozzle of head 2. If your nozzle is more than .100” or 2.5mm above or below the
setup block (which is unlikely) you may need to adjust the zprobe screw or zprobe bracket; these
adjustment procedures are at end of this step, should it be necessary.
Begin by adjusting the back left leveling screw (found underneath the bed) with the supplied 7mm
nut driver. Note: There are three leveling screws with heavy duty springs. When you adjust the
leveler your are actually moving the 4mm hex nut. For now, only adjust the left back leveling screw.
Turn the nut driver clockwise or counterclockwise until the block and business card slide under the
nozzle. The block should make slight contact with the nozzle tip.
Next, slide head 2 to the far right of the gantry, as shown below. Adjust the rear right leveling screw
until the nozzle makes slight contact with the setup block, just like you did on the left side.
