🔧 Assembly Instructions

⚡ Mount the Motor
Attach the NEMA 17 stepper motor to its mount.

🔩 Assemble the Main Block
First, screw in the screws into the two small brackets, then attach them to the main block to simplify the assembly.

🌀 Install the Auger Screw
Insert the screw until it makes contact with the edge of the main block. Due to its slight elasticity, you may need to apply extra force and gently tap it to achieve the final millimeter of insertion.
⚠ Caution: Be careful not to break it! The tight fit prevents any play, ensuring a secure and precise rotation.

🔒 Secure the Closing Piece
Fasten it with 3 screws.

🛠 Finishing Touches
Pre-tighten the clamping screw, position the piece in its final location, and finish tightening the screw.
