Function

Test Description Target Tolerance
Brass inserts Check for presence and size of brass inserts. All inserts must be present and of the correct threads and depth. N/A
M3 screws Insert M3 screws into M3 holes to ensure fit. Screws should be insertable without interference. N/A
M5 screws Insert M5 screws into M5 holes to ensure fit. Screws should be insertable without interference. N/A
Nut bars Fasten nut bars of appropriate lengths between holes according to FarmBot system design. Nut bars should be fastenable without screw/hole interference. N/A
Extrusion fit Fasten part to an extrusion according to FarmBot system design. Part should mate with extrusion slot as intended. N/A
Cable carrier fit Fasten cable carrier end pieces to cable carrier supports. End pieces should fasten flush to mounting surface and have adequate clearance on sides. N/A
Vacuum pump fit Fasten together the vacuum pump, vacuum pump mount, vacuum pump housing, and the z-axis extrusion according to the FarmBot system design. The vacuum pump and mount should fit inside the housing without interference. N/A
