Checkpoint B03

Checkpoint · Batch B03 — A/B drive units + front idlers

• Gate B passed before B03-P1 started
• F695 flange seats in a/b_drive_frame_lower/upper caliper 15.00 mm ±0.15
• (kit day) a real F695-2RS sits in each seat with no rocking
• Drive unit halves (upper+lower) close flat with no visible gap, both A and B
• No corner warp on any of the eight parts
• A-side parts in 04-A, B-side parts in 04-B

Batch B03 printed: plate 7 of 22, 57.2 of 157.0 h. 1 gummy worm.

Common mistakes

• Mixing A-side and B-side parts in one bag — they are not interchangeable.
• Force-closing a warped drive-frame half instead of reprinting it.
• Skipping the dry-fit and only discovering the bearing-seat gap during final assembly.
