What this video covers
Michel and Marina construct a custom 3-meter CNC machine from scratch to cut aluminum plates for their catamaran project.0:14 The build begins with a detailed digital design, followed by the fabrication of a steel table base.0:31 To ensure precision, Michel uses a 3D-printed jig for alignment and performs cross-welding techniques to minimize heat-induced warping.1:23 The mechanical assembly includes mounting racks and pinions, which require exact spacing to prevent gear slippage.4:23 For the electronics, the pair integrates NEMA stepper motors, 48V power supplies, and a spindle controlled by a variable frequency drive, sourcing all components from Ocean Tech.9:30 The control box is laser-cut for precise fitment, allowing for easy threading and assembly.11:22 After configuring the motor drivers and calibrating micro-stepping parameters, the machine successfully completes its first movement test.17:46 The project is designed for low-cost construction and high precision, with the developers now offering the build plans and instructional resources through a dedicated platform.14:20
