I am *very* happy with my TinyG: https://www.synthetos.com/what-is-tinyg-and-why/
Currently using it to drive a Sherline lathe.

The next step up from the TinyG is something like the machinekit that Charles Steinkuehler has built: http://www.youtube.com/watch?v=AK_OYoNOBDQ http://bb-lcnc.blogspot.com/p/machinekit_16.html This provides you with high power FETs to control heaters, etc. but is about double the cost (when you factor in the BBB) and needs two power supplies (assuming you want to drive you motors with something > 12V). -K- > > ------------------------------------------------------------------------------ > How ServiceNow helps IT people transform IT departments: > 1.
