   I bought a Proxxon MF70 a while back (link), it's surprisingly high quality but also has an unfortunately small range of movement. I'm considering building an extension to the milling bench or just buying a larger one and mounting it, but that's for another time.
   
   I'm planning on converting the machine to CNC; I've bought some basic mounting plates for NEMA17-sized motors (link, pretty good quality, tight fit/low clearance etc) and am now deciding on a controller.
   
   I'm currently looking at this motor/controller/driver/psu kit, thhough to be honest I've done fucktonnes of reading on diy forums and am still not sure exactly what to look for. I'm aware I can use an arduino for a controller and shields/daughterboards for drivers, but as I haven't done this before I'm afraid of damaging parts through over/undervolting it and I'm not sure all the diy parts together will come to much less than the $200-300 asking price for full kits on ebay.
   
   
   I know it's a long shot but I'm curious if anyone here's done similar and has advice.

   Wish I could be more helpful. Looked into DIY cnc machines but they were 1. too expensive and 2. to limited. What you have set up seems like a solid start for what you are planning on converting. Good luck and keep us updated so at the least I learn something.

   a drill press is not designed to handle the lateral forces of horizontal cutting, best case it cuts inaccurately, worst case you fuck the motor up like I said, the MF70 is surprisingly capable, I've cut all sorts of things up to annealed steel (plastics, varying thicknesses of aluminium and carbon fibre up to billets of 'damascus' steel)

   I've been reading up on CNC lately and wanted to build a 3D printer but it never really went anywhere. I did buy some Nema17 motors and drivers but I'm not sure if those would be fit
