Im trying to build a cnc milling machine but cant find a suitable stepper motor controller that works with emc linux and fits my budget. Does anyone know of any simple and cheap Computer stepper motor controllers? I dont have the knowledge or equipment to be using pics or micro controllers so tha sets me back again. Help would be greatly appreciated.
I bought a really easy to use stepper I2C serial motor controller from here www.byvac.com, you can also get serial ones that work from a com port.
Stepper motors can also be directly amd more precisely controlled over the parallel port; All you need is a program that will write the appropriate bits to the data lines in sequence and have them switching transistors to fire the windings in the motor.
is there not usb controllers for this yet? i would have thought someone would go with new technology.
