Hi everybody. I'm currently in the process of converting a SIEG Super x3 milling machine using the deluxe kit from CNC fusion (
http://www.cncfusion.com/smallmill1.html). Anyway I'm asked my electronics supplier to specify a suitable kit to complete the conversion (see below). Being a bit new to this I thought I'd get s second opinion on whether you think the specification is suitable. Any advice would be much appreciated. Thanks, Will
