11. Gently tighten the locking screw(1). Be sure that extruder assy won't freely slide up or down (but yet no excessive
torque will be needed to pull it up – DO NOT OVERTIGHTEN)
12. Try to push a bit of A4 copy paper between nozzle and printing plate: paper must not pass
13. Gently screw in the pipe adapter (it will pull up slowly the extruder assy) stop as soon as paper will find enough
clearance to pass between nozzle and plate. Do the same for ALL nozzles mounted
14. Move down printing plate, to gain better access to setting screws.
15. Lock setting screws (1) and (2) for each extruder
