EShapeoko 1.2 Assembly: X and Y motors

Note that the left and right Y carriages must be mirror images of each other. As looking into the shaft of the motor, the left motor plate should have the cut off corner on the left, and the right motor plate should have it on the right. The X motor plate can be positioned either way, but it is illustrated here with the cut off corner on the left.

NEMA 17 Motors

There are three supported configurations for the motors, belts and idlers when using NEMA 17 motors.

VIEW OF Y AXIS

This is the default configuration for the X axis. Extra parts are required to implement it on the Y axis.

Bolt the motor to the motor plate using the M3 screws, with one washer each. Use the top NEMA 17 hole pattern.

Install the idlers using 6.35 mm spacers in the holes shown. Orient them with the protruding bearing closer to the motor plate.

If using this configuration on the Y axis, this depicts the left Y carriage. The right Y carriage is a mirror image (it has the cut off corner on the opposite side).
