Do:
- Look through the retainer's window: the closed loop circles the 80T inside, with slack hanging out to reach the motor pulley.
- Repeat Steps 02.22–02.26 until all four drives are closed, two

Check
In every drive the belt is visible inside and free to move; four drives closed.
What you're looking at
Manual p.37: the assembled drive with the belt loop visible inside it. The loop leaves the housing through the retainer's rectangular window, the face with the six insert heads, and must hang out far enough to hook over the motor's 16T.
Good stopping point · ~35 min since the last one
all four drives closed: shafts seated, retainers down on six M3×40 each, blue baseplates on with their captive M5 nuts, belt loops captive and free. Each drive is one ~9-minute unit, so if you stop earlier, stop with a drive fully closed and its baseplate on — never with a drive half-closed.
