I'm looking at purchase of an old CNC tool and cutter grinder. Control still runs but has problems http://tinyurl.com/g4wwb
If I purchase, I would need to record what each cycle does in terms of stepper pulses. And then convert this to a math equation for an eventual new control.
Is it possible to capture stepper pulse output back to a computer and analyse the data? How would I go about this?
