3DFUSED Y AXIS INSTALL GUIDE
This is a install guide for all Y kits the images are reference and will be different for each printer
Step :1
Remove all stock components from the Y axis extrusion so the extrusion is as shown below
(note: CR-10 and larger style not shown but the concept is the same.)

Step :2
Remove the extrusion hold down screws on any smooth faced Y extrusions
(note: on the S1 & S1Plus leave the rear bolts installed as shown below. on the CR-10 or larger printers remove only the front and rearmost bolts leaving the center bolts installed)

Step :3
Install Y axis kit on top of the extrusion and secure
T slot extrusions it is best to preload the included hardware and Tnuts. Some kits will include 6MM aluminum spacers to raise the kit up for clearance.
(note: on the ender 3 the single rail kit installs by (3) M3 SHCS through the rail mount holes of the rail)

Step :4
Install the motor and the limit
(note: the motor drive gear may be too high and some motors gears need to be pressed down to get the belt running parallel this is possible with a socket and some pressure but the easiest way is to replace the motor with a D shaft stepper and a adjustable drive gear.)

Step :5
Install the bed and level
(note: the printers home offset may need to be adjusted you can learn how to do that here)
