Step 02.01: Parallel Linear Rail Alignment
Fix rail A firmly against extrusion datum. Run the carriage across rail B with a dial indicator touching rail A to verify parallel alignment across the 800mm travel.
Step 03.01: Mounting Z-Plate Leadscrew
Seat the 1605 ballscrew nut into the milled aluminum Z carriage plate and torque flexible shaft couplings to NEMA 23 motor.
Step 04.01: Shielded Cable Grounding & Ferrite Beads
Route 4-conductor shielded motor cables through drag chains. Ground copper braid shielding strictly at the control box star ground plate.
Step 05.01: Fly-Cutting Spoilboard Surface
Mount a 1-1/4" carbide flattening bit. Run a zig-zag pocketing toolpath with 40% stepover and 0.5mm depth of cut across the wasteboard.
