I recently bought a small milling machine (similar size to an X3) which I plan to CNC in the near future. The machine will be used for hobby type jobs like making me a CNC router in aluminium and steel. I have almost no experience working in metals but have a desire to learn.

So to my question; what would be a good resolution to aim for in my machine? I know this is not the same as accuracy but I believe higher resolution means higher accuracy from the machine. I also know that high accuracy comes with higher quantity components and design.

I will be using 200 steps/ revolution stepper motors with a +/- 5% accuracy per step.

I know this is a hobby machine but I would like to be at the higher end of accuracy or at least what is within my budget.

As always all constructive opinions are appreciated.
