These have been found to make simpler and more robust couplers. You should screw the **M6 rod 1/3 of the way down** the tube, then push it onto the shaft and squeeze and pull it down to constrict on the rod like a finger trap.// | ||

| Take out the four Z coupler halves, which are used to attach the stepper motors to the threaded rods. Half of the holes have hexagonal outlines, indicating nuts go there. | Take out the four Z coupler halves, which are used to attach the stepper motors to the threaded rods.

| The UHMW tape is actually transparent. The blue stuff is the backing that must be peeled off. Separating the two can be fiendishly difficult. Basically, abuse a corner of the tape until you see the transparent layer starting to separate. Grab the two layers with the edges of your fingernails and peel the backing off. Throw the blue backing layer away immediately, otherwise you might later confuse it for another piece of unseparated tape. | The UHMW tape is actually transparent.

| Slide the X right end up and down and verify that it moves easily and isn't trying to fall off the frame. It may rotate a bit in the X-Z plane, but don't worry about that, it will be stabilized when the X axis steel rods are installed later. | Slide the X right end up and down and verify that it moves easily and isn't trying to fall off the frame.

For a small gap then you could use a couple of rectangles cut from the rigid, clear plastic "clamshell" packaging they use just about everywhere these days or thicker "takeaway" plastic containers (both normally PVC). Drill-out a 3mm hole, trim to the size of the Z slide (remembering to remove any sharp corners - this stuff is lethal) and then stick them to the back of the Z slides when satisfied. This is not shown here. |
