I started to research a CNC coil winder last spring but shelved it due to more important projects. Something the size of the shuttle motor in an ink jet printer would be sufficient for the wire quide and maybe a 25 oz.-in. stepper for the coil driver. Any ideas for the tensioner encoder?
There are a couple of programs that are available for software development, like Vbasic. I've yet to find any shareware for coil winders.
Xylotex would no doubt be a nice controller for this type of application. Or, maybe something open source.
