What are some of the things I should keep in mind if comparing these? Is one a mill for harder metals and one the CNC for larger projects maybe not metal?
So the MiniMill is a small (5x5" work area) lead screw driven machine where the OX tends to be a larger belt driven machine. The leads and belts have their own advantages and disadvantages but the basics in our system are; Belts are faster and can be larger builds but a little less accurate over all Lead screws are more percisce, more powerful for material removal but are usually smaller builds. Hope this helps
