What power stepper motors do I need?

Thank you,

Just out of interest, what sort of machining accuracy should I expect with the above CNC’d ?

Clamp a DTI to the bed.
Run a tool up against it.
Lean on the spindle and measure the deflection.
That tells you what is possible.
Achieving 'possible' is the tricky bit :naughty:
