| If there are any motors or endstops that aren't installed right now, install them. The adjustment procedure for the Y axis endstop is [[jitsbuild-y-axis#adjust endstop|here]] (read the whole procedure before starting); the X axis endstop is adjusted in a similar way. All of the endstops will probably need to be adjusted at least once more after this. | If there are any motors or endstops that aren't installed right now, install them.

| + | Another idea is to use the channels in the aluminium extrusions to conceal these wires. The channel along the bottom of the frame can be used to hide the left-hand Z motor cable and Z endstop cable (optionally if you desolder and resolder the endstop cable you can even conveniently feed this down through the channel between the side and bottom frame pieces). Similarly the underside of the Y axis and then the rear channel of the bottom frame piece can be used to route the Y axis motor and Y endstop cables over to the Azteeg controller. A few balls of Blu-tac are a good way of holding the cables inside the channel. | ||

| Here, all of the bundles have been brought together at one point, under the controller, and attached together with a cable tie (excluding the wires from the left Z axis motor, not visible here). The big bundle from the X axis approaches from the right, and the other bundles from the left; this helps to keep the bundles oriented appropriately as things move around while printing. The bundle from the heated platform (which you may not have) has been placed on top of the other two coming from the left, so that it can move freely. | Here, all of the bundles have been brought together at one point, under the controller, and attached together with a cable tie (excluding the wires from the left Z axis motor, not visible here).

| Move the X carriage and the Y carriage back and forth, all the way, to make sure the bundles of wires are long enough and there are no interferences anywhere.

| - | Not documented very well so far is the application of polyimide tape to each hot end heater block for thermal management (but see [[hot-end-thermal-management|here]]). Better ways of shielding the high-voltage terminals need to be documented. Improvements to these parts of the documentation are still needed. | ||
