Y-Axis Install
When installing the Y Axis rail kit on the, install one side at a time
Do not allow the bearing blocks to slide off the rails. You can use masking/painter's tape to stop the bearing from sliding off.
Step 1
- Remove all 4xM5 button head Screws one side at a time (yellow circled)
- Remove Black 2X M5 socket head screws (blue circled)
Step 2
Build the rails with M3X8 Socket head and Sliding-Tnuts Leveling 2 spaces between mounting point on the rail
The included Printed guide will help to square up the Tnuts
Y end stop Side
- Slide in the printed alignment tool
- Slide the rail and use the printed part as a rail as a rail stop.
- Use the included Rail alignment jigs to center up on that side to the extrusion
- Flip the Alignment tool over
- Slide the rail and use the printed part as a rail as a rail stop.
- Slide the stop down till it hits the printed part
Step 3
- 4x M4x25
- Y end stop mounts with 2x T-nuts and M3 screw from the stock End stop flag mount are reused
- 4x M3x16 Socket head screws
Be sure to start all new fasteners before tightening any. It may be easier to start the M4 bolts (w/ washers) into the frame and finger tighten. This will free up one hand. Next, move the linear rail block to line up with the bracket and start all 4 m3x16 bolts by hand—since you are tightening against aluminum, the only risk is if you cross thread these fasteners.
The bottom of the bracket should be aligned with the X Axis frame. You can use the side of a digital caliper, 3/4mm hex key or any straight edge thin enough to fit.
