Hello all,
I am attempting to construct my own small CNC mill using the circuitry found here: Easy to build CNC Mill Stepper Motor and Driver circuits
I have one axis of the machine wired up, but I'm stuck. For protecting the motor, the gentleman who designed it used a small light bulb in place of a resistor. I would prefer to just use a resistor as I don't have access to the same type of bulbs he used. I'm just at a loss as knowing what type of resistor to select. How do I figure out many ohms/watts it needs to be rated for?
Thanks,
Steve
