For converting a HF Mini Mill (sieg X2) to CNC, is it better to direct drive the axes like the Steele plans or belt drive the axes like the fignoggle plans? I'd like to use the HobbyCNC system because it is the cheapest I've found. Is there anything else out there for a comparable price? Are 200 oz-in steppers sufficient for an X2 conversion? If not, can I use the 260 oz-in steppers from homeshopcnc with a driver board from hobbycnc?
