Do:
- Work on the gantry off the printer, upside down, A/B motors up.
- Lay one belt end on a front idler's or drive's serrated pad, teeth down.
- Leave ~10 mm of belt past the pad.
Check
Belt teeth are meshed into the pad's serrations, not sitting on top of them. The belt leaves the pad straight, not skewed.
What you're looking at
The first belt end goes onto the serrated pad under a gantry corner, a front idler or A/B drive, facing up while the gantry is upside down. Teeth down, the belt meshes into the plastic and cannot creep under load.
