I need reliable 2-axis CNC programs that will let me cut a series of aluminum parts accurately and repeatably. You will receive the dimensional information I have—this may be a simple sketch, a DXF, or a solid model—and from there I want complete, ready-to-run code for my machine. I work primarily in aluminum plate, so optimal tool selection, feeds and speeds, ramping strategies, and safe entry/exit moves are important. My machine reads standard G-code; if you create toolpaths in Fusion 360, SolidCAM, Mastercam, or a comparable CAM package, just export the post-processed code along with a quick setup sheet so I can verify tools, zero points, and overall cycle time before the first run. Deliverables • Clean, collision-free G-code files for each part • A brief...

⚠️ This is NOT a design, CAD, CAM programming or 3D printing job. Nothing new is made, modelled or programmed. We only want files that already exist from real production. Start your bid with your shop name, city and machine list (make, model, control). Bids without them will be ignored. What we’re looking for Machine shops (or people with the shop owner’s permission) that have past 3-axis milling jobs programmed in Fusion 360 and machined on their own machines. Everyday mechanical parts are ideal: brackets, plates, housings, fixtures, or your own products. Files from a shop that has since closed or stopped production also qualify, as long as the parts were really machined and you have the right to share the files. For each part, we need the files you already have: 3D mode...

This project strictly requires hands-on prototyping, including physical assembly and testing—design-only services will not be considered I already have detailed winding diagrams, coil counts, wire gauges, and a full wiring schematic for three compact electromagnets—each under 10 cm in any direction. Your task is to turn these drawings into a tangible proof-of-concept and ship it to me. The magnets will sit in a custom harness. I’m leaning toward a light alloy or other metal solution, but I’m open to your recommendations once you see the design constraints. All electronic components, fasteners, and raw materials will be reimbursed at cost; please keep receipts. Power can come from batteries, a small AC supply, or a rechargeable pack—I’m happy with which...
