검사 이름과 파라미터 이름은 CAD 엔진에서 그대로 나오기 때문에 영어로 표시돼요.

• ✓Links never touch at rest0.4 mm joint gap at every pin, plate and stop face
• ✓Pins are captureda link shifted 0.92 mm sideways or 0.70 mm along the pin hits its neighbour (2.65 / 83.20 mm³): the cone pins sit in the sockets between the cheeks and cannot pull out
• ✓Bends freely to the bend angle30.2 degrees per joint gives a 50 mm bend radius at a 26.0 mm pitch (6.0 links per half turn)
• ✓Stop at the bend angle4 degrees past the bend the tooth is into its pocket wall (3.22 mm³)
• ✓Stays straight the other wayreverse bend stops within 2.25 degrees per joint (tooth on the straight stop)
• ✓Upper run is self-supportinga 100 mm stick-out puts 0.98 N on each stop tooth (0.06 MPa shear; PLA allows 5.0); stop play lets the longest upper run (6 links) sag about 4.6 mm
• ✓Pins take a hard tug30 N pull on the chain: 0.48 MPa shear in the two 6.3 mm cone pins (5.0 allowed across layers)
• ✓Cables lie free in the chainoverlap 0.00 mm³ straight and 0.00 mm³ in the U at mid travel
• ✓Cables bend gentlythe bundle bends at 52.6 mm in the U, at least 7.5 x the 5 mm lead (37.5 mm, chain-rated cable)
• ✓Cables stay inroof slot 4.25 mm vs 5 mm leads: each lead presses in past the 50-degree lips and cannot fall out
• ✓Travelmoving end runs 150 mm (of 150 wanted, 158 mm possible) with the U 119 mm tall
• ✓Every body starts on the bedprinted standing up: every link and bracket rests on its -Y edge
• ✓Bracket ears hold the chaina 30 N tug puts 7.4 N on the far M3 screws; 1.32 MPa in a 4 mm ear (16.7 allowed)
• ✓Screws seat on the earsM3 heads (5.7 mm) land flat on 4 mm ears, clear of the gussets; 3.1 mm of ear outside each hole
• ✓drag chain stays together after printingall 11 bodies are captive: none can be pulled out along any axis
• ✓drag chain is held firmlyevery captive body is held by at least 0.8 mm (two perimeters)
• ✓lead 1 (5 mm) goes in166 poses along its path clear of every part.
• ✓lead 2 (5 mm) goes in166 poses along its path clear of every part.
• ✓lead 3 (5 mm) goes in166 poses along its path clear of every part.
• ✓M3 screws: fixed bracket goes in15 poses along its path clear of every part.
• ✓M3 screws: moving bracket goes in15 poses along its path clear of every part.
• ✓driver: fixed bracket screw goes in15 poses along its path clear of every part.
• ✓driver: moving bracket screw goes in15 poses along its path clear of every part.
