Homemade DIY CNC machine project

Excited to share an old project from 3 years ago, the user uploads images of their CNC machine's older version and shares its recent upgrades in a 3D model. This computer-driven machine can perform various tasks depending on the tool attached, but due to being belt-driven, it isn't suitable for milling metals or wood. The user has used it as a plotter and recently mounted a drill for styrofoam milling and casting aluminum models. The slides are from drawers, and belts are from old printers, with 18mm MDF used in the build. The motors are bipolar, driven by a homemade controller named "chimera," which can also power a laser for cutting paper. A recent upgrade includes using a USB converter instead of an LPT port. Two videos demonstrate the machine's capabilities as a plotter and code-making process. If there's interest, the user may provide pictures of aluminum models made this year. Interested parties are encouraged to comment with questions.
