Z Axis Simplification
We are replicating Chris Palmer's HydraRaptor z axis as described on Chris's Blog. Here are the changes required:
My z-axis removes all the RP parts with a z-prefix. it also loses a lot of M8 nuts and washers, two M5 bolts that hold the motor bracket and 4 M5 bolts that hold the motor, plus the belt of course. The four lengths of studding become all the same length and a bit shorter. Mine are about 270mm. They depend on the motor height and shaft length.
Additional parts are: -
- 4 M4 x 50 cap screws to hold my motor brackets vertically.
- 4 M5 x 40 cap screws to hold my motor brackets horizontally.
- 8 M4 x 45 cap screws to hold the motors.
plus nuts and washers of course.
Also about 100cm of plastic tubing that is a tight fit over M8 thread.
