Route the belt

If you have trouble inserting the belt, it might be due to an extrusion multiplier issue (over-extrusion) or due to the use of a non-genuine or non-2GT belt. Check the step 5 of Preflight check and disassembly chapter for more details.

Add the bottom of x_carriage_back as shown in the second image. Make sure to not pinch any wires. You should not have to use any force to close it

Secure the x_carriage_back with an M3x18 screw

And two M3x10 screws

Double check that no wires are pinched, this is very important!
