What you're looking at
Manual p.41: four M5 roll-in T-nuts loaded into the two bottom extrusions meeting at this corner. They are the threads for everything that bolts down here: two for the drive body's M5×40, two for the motor foot's M5×10. The drive-end one also pins the cam.
Tip
Skip the loading if you pre-loaded this corner's T-nuts at Step 02.11.
