[title] Back X Carriage Idler Installation
-[* black] Install the idlers on the Back X carriage
+[* black] Locate the X carriage labelled as the "Back".
+[* black] Insert an M3 x 10mm Button head bolt into the bottom of the X Carriage, and an M3 x 16mm bolt into the long horizontal hole in the X carriage, until they're flush with the inside edge.
+[* black] Begin by holding a 25mm shoulder bolt so the threads are pointed up. Place (3) M5 washers on the bolt, followed by (1) M5 shim. Next put on a smooth idler. Then another M5 shim, then a toothed idler, followed by a final M5 Shim.
+[* black] Visually look to see that the final shim is very close to level with the "shoulder" of the bolt.
+ [* black] If there's a gap, see if it's best filled by a shim, or a washer. You want to place those before the first shim you put on.
+ [* black] If instead the shim sticks out past the shoulder, you may need to remove a washer and replace it with a shim.
+[* black] Once the "stack" is level with the shoulder, thread it into the X carriage (I leave the shoulder bolt pointing up, and turn the X carriage down onto it, being careful not to cross-thread it). The shoulder must be tight against the X-Carriage, with as little vertical play as possible.
+[* icon_caution] The shoulder must be tight against the X-Carriage, with as little vertical play as possible. If the idlers don't spin smoothly, it's too tight and you need to remove a washer or shim. THERE MUST ALWAYS BE A SHIM DIRECTLY AGAINST EACH SIDE OF THE IDLERS.
