Getting Started

The printer I use with the 3D Chameleon is way up high on a shelf. I created some simple stepper motor rotators so I can see when filament is being driven in/out and also what filament is being unloaded and loaded. There is an oversize gear for the extruder and a windmill for the selector (sorry I didn't have that exactly aligned for this video, needed 3 hands! but you get the idea).

I used a pressure-fit 8x3mm neodymium magnets I ordered on ebay:

N52 Super Strong Neodymium Magnets Discs Collection. Neodymium Magnets are made of a brittle material (NDFEB). These magnets are not as strong as steel, they are more like a brittle ceramic. Neodymium magnets are brittle, and can peel, crack or shatter if allowed to slam together.
