The prompt
Design a manual roller-blind fabric cutting table for a small workshop, welded steel (PTR square tube 2" gauge 14), no motors. Deliver plan/front/side drawings in mm, exploded isometric, cut list and BOM with commercial parts. Top 4000 × 3000 mm at 900 mm height: 19 mm MDF with white HPL, 6 legs with leveling feet, 3 longitudinal rails + 5 cross members, diagonal bracing. Datums: fixed rectified fence along the rear long edge (Z = 0) with adhesive tape and a flip-up length stop; transverse cut line at X = 0, 525 mm from the left end, with a 6 mm slot and replaceable nylon insert. Transverse cut: fixed floor gantry (2 posts PTR 2", beam PTR 2×4" 3400 mm, 60 mm above the top). Left face: HIWIN HGR15 rail 3100 mm with a hand-pushed carbide blade carriage. Right face: second HGR15 rail that guides the longitudinal bridge. Two aluminum pressure bars 60×30×3120 with EVA, 130 mm each side of the cut line, each with 2 pneumatic cylinders Ø32×50, one 5/2 foot pedal valve. Longitudinal cut: bridge PTR 2×3" 3400 mm running in Z, left end on the gantry rail, right end on an HGR15 rail 3000 mm along the right short edge; hand clamps at both ends, tapes zeroed on the fence; HGR15 on its front face with a knife carriage cutting flush on the HPL. Roll feed at the left end: 2 A-frame posts with a comb bar at 981 mm holding 3 galvanized 1½" × 3000 mm shafts with friction brakes. Tube rack under the table: 2 levels (300 and 600 mm) of PTR rails with ½" rod pins every 160 mm for 38 and 45 mm tubes up to 3900 mm, front side open. Accuracy: transverse cut square to the fence within 1 mm over 3 m; describe the squaring procedure (3-4-5, diagonals of 5000 mm) and rail shimming. Stock PTR is 6.10 m; optimize the cut list. Flag safety and structural issues (blade guard, pinch points, bridge stability) and propose fixes.
