-
X and Y motors and pulleys are all identical components, but the X pulley needs to be installed differently than the Y pulley.
-
-
-
Slide the Y pulley onto the Y motor shaft.
-
The thin flange side of the pulley faces away from the motor - towards the top of the motor shaft.
-
-
-
Align the top of the shaft with the top of the pulley.
-
Tighten the set screws well.
-
Tighten as much as you can without damaging the thread (so called 'stripping').
-
Make sure one of the set screws is against the flat side of the motor shaft. This prevents the pulley from spinning around.
-
-
-
Same as putting the thread lock onto the Y Pulley set screws.
-
Take out two set screws out of the pulley, put thread lock into their threads, and put them back into the pulley.
-
-
-
Slide the X pulley onto the Y motor shaft.
-
The thin flange side of the pulley faces the motor this time (the opposite from Y pulley on Y motor.)
-
This X motor pulley alignment is very different from Y motor pulley. Follow the instructions closely.
-
-
-
Slide the pulley as far away from the motor as you the set screws still can fully grip the motor shaft .
-
The X pulley will be extending about 3mm (0.12'') beyond the top of the X motor shaft.
-
Tighten the set screws well.
-
Tighten as much as you can without damaging the thread (so called 'stripping').
