X Axis
Note: all PN are our PN not manufactures #
1. Begin by locating the 2 X Axis Rails (PN 2436-01-04). Be sure the parts are cut to correct length and the end holes are tapped.
2. Connect the X Axis Endplate (Bearing End – PN 2436-01-03) to the 2 X axis Rails with (4) 5/16 – 18 hex head bolts 1 ¼” long and 5/16” washers. Be sure to use the lower holes of the endplate. The 1 1/8” diameter bearing hole will be at the upper half of the endplate when installed. Your
assembly should look like this:

3. Assemble the 4 8020 Brand #6725 Linear Bearings (PN 2436-01-05). Do not worry about using the shims that are provided at this time. Set these aside for later use.
4. Install the 4 bearings onto the X Axis Rails. Place 2 of the bearings onto each rail. Your assembly should look like this:

5. Connect the X Axis Endplate (Motor End – PN 2436-01-02) to the 2 X axis Rails with (4) 5/16 – 18 hex head bolts 1 ¼” long and 5/16” washers. Be sure to use the lower holes of the endplate. The 1 1/8” diameter bearing hole will be at the upper half of the endplate when installed. Your assembly should look like this:

6. Connect the 2 x axis cross members (PN 2436-01-06) to the bearings using (16) 5/16-18 hex head bolts ¾” long and (16) 8020 brand t nuts. The cross members are to be bolted up through the holes in the bearings with the t nuts fitting into the T-Slots. I found it easier to loosely install the bolts w/ the T-nuts onto the bearings and then slide the crossmenber connectors onto the T-Nuts, position correctly and then snug bolts. The cross members should be flush to the outside of the bearings. Your Assembly should look like this:

7. Connect the X Axis Cross Member Connector (PN 2436-01-07) to the X Axis Cross Members using (6) 5/16”-18 hex head bolts 1 1/4” long, (6) 5/16” washers and (6) 8020 Brand T-Nuts. Use the 6 holes closest to the perimeter of the board. Again, it was easier for me to install the bolts and T nuts and then slide the part onto the extrusions. Be sure the board is flush with the edges of the cross members and try to center it on the extrusions. Your assembly should look like this:

8. Install the X Axis Nut Carrier (PN 2436-01-10) on the X Axis Cross member Connector . Use (2) 5/16-18 Hex Head Bolts 1 ½” long, (4) 5/16” Washers, and (2) 5/16” hex Head Nuts. Your assembly should look like this:

9. Install the (2) X Axis End Bearing (PN 2436-01-12) into the X Axis Endplate (Bearing End) – One from each side. This is simply a press fit. Your assembly should look like this:

10. Install the X Axis Lead Screw Nut (PN 2436-01-11) to the X Axis Nut Carrier using (2) ¼-20 Hex Head Bolts 1“ long, (4) Washers, and (2) Hex Nuts. Your assembly should look like this:

At this point the X Axis is complete other than the Lead Screw. We will wait until later to install this item. If we install it now, it will keep us from being able to adjust (shim) the motion of the X Axis. We will also wait to adjust the motion of the X Axis until the remainder of the machine is complete. This is because we want to have the weight of the complete machine on the X Axis when adjusting.
