Step 29 of 39 with a helper · Chapter 07 — A/B belts and tensioning

Parts: none.
Do:
- "Make sure that the belt is not riding on the plastic parts." Look at both belt edges entering and leaving every stack.
- Repeat with the gantry at the extreme front, the extreme rear, and both ends of X.
Check
Visible daylight between both belt edges and the printed part at every stack in every position. No witness marks, dust, tick or squeak.
Helper Watches one side of every stack as you move the gantry and calls out any rub.
What you're looking at
Fourteen belt contacts at six locations: two per XY joint, one per front idler, and four per drive: two S-wrap stacks, the motor pulley and the other belt's stack. A belt riding a printed flange ticks once per revolution.
