Parts:
- the A belt · already on the bench
Do: Take the returning run rearward to the right XY joint. Wrap it 90° round the joint's toothed idler, teeth meshing, then bring it left along the X extrusion to the X carriage. Leave the tail loose there.
Check
A is now a closed path, both ends at the carriage, teeth on the right joint's toothed idler and smooth back everywhere else.
What you're looking at
The right XY joint closes the A loop. The belt wraps the joint's upper, toothed 20T idler teeth-on: the return run doubled back at the front idler, so its teeth now face inboard. This is correct, not a mis-route.
Soft stop (not a Pause): if you must break here, tape the loose A tail to the X beam so it cannot pull back through a stack. On resuming, walk the six A wraps with a fingertip before starting Step 07.17.
