**jit's build: Y axis** (Go back up to [[jitsbuild|jit's build]]) Find these: {{wiki:jitsbuild:y-axis-subassemblies.png}} The three metal parts on the left will be shorter if you have a 5" model. Start with the Y front end (the printed part without the motor). Loosen the two M5 screws until the nuts are flush with the ends of the screws, and then loosen them a bit more (but not enough so that the screws fall out of the nuts). Insert the aluminum extrusion the only place it can go (check image below for which end to use) and slide it all the way in. You may have to adjust the height of the nuts to clear the edges of the channel. When the extrusion is fully inserted, tighten the screws. Do the same thing with the Y back end. Be careful that you don't damage the endstop or its wires, if you have already installed it.

Pop two linear bearings out of their holders on the Y carriage, and insert one of the rods through them. Move the bearings apart a bit; you can use them as a handle when handling the rods in the next step, which helps to keep the rods and your hands cleaner. Do the same for the other rod. Install the rods under the fender washers, using whichever technique works best for you. You may have to loosen the fender washer screws; don't lose the nuts on the other end. {{wiki:jitsbuild:y-axis-withrods.png}} Next, we install the Y axis synchromesh cable. Get one of the synchromesh cables, and find that last tiny part from the Y tensioner sub-kit. Turn the Y carriage upside down. Place the small semicircular Y tensioner on the end of the Y tensioner screw, and retract the screw until the Y tensioner is fully retracted: Loosen the bearing holder screws a bit, so the holders can be rotated.
