      • Set the torque driver to 0.5 N/M for this step
    • Use the 8mm wrench to hold the nozzle-holder stationary while applying torque from the rotary-pneumatic-adapterside
    • The rotary-pneumatic-adapter should be installed closer to the motor's cable connector

  2. Loosely bolt 4x M2.5x8mm-socket-head fasteners into the front face of NEMA11-hollow-shaft-stepper

  3. Package this completed assembly into a 4" x 4" Red ESD Bag and then roll it up

Prepare Extra Toolhead Cable Labels
