There's no think, engineering a machine is all about calculation. If you don't know the formulas, don't design a machine. If you realy want to desing a machine, get some skills. CNC mills and 3D printer are ways different. A mill is a bodybuilder while the 3D printer is fitness. The mill needs mass while 3D printer do not. It can't be good on both application, and compromises will make the machine clumsy for both jobs. They don't work at the same speed. To make a good mill, it will cost you about $1000, and a correct home made 3D printer starts around $300. Building a dual function machine will also cost you much more than two separate machines. No economy here, or you'll get a bad tool. A pure CNC mill will need strong motors, if you add a 3D printer head, you'll need them to be also fast and agile, so it will be more expensive. The sames principle apply on many components. Don't waste that money on a clumsy machine. Otherhand, a CNC Mill produce a lot of dust and chips while a 3D printer needs to stay dust free. To me, one function equals one machine. Maybe start with a proper 3D printer, then save money to build a good CNC mill.Quote

I'm planning on using this as double duty, a 3d printer and a cnc machine.
If I go up to 12mm do you think the mass would be too high to move with nema 17 motors?

I'm planning on milling only small acrylic and pcb boards, not metal.
