For a long time I've been contemplating somehow acquiring a CNC machine as a tool to compliment my hobbies and also to further my education of CNC manufacturing. I've worked with CNC programming and machining as part of my job all my life. To be able to configure and build a machine using the type of components OpenBuilds offers is for the most part perfect for my needs. However I would like to have a CNC controlled variable speed spindle rather than a woodworking type router. I am having difficulty finding information for putting together a machine with that type of spindle. I looked around on this forum to see if i could find anything and i am just not seeing it. Can anyone help?
