Hi, I'm currently building a CNC machine and am using an arduino mega 2560 to control the auxiliary functions of the CNC controller. I've written most of the program and tested it on a breadboard. In amongst it I am going to read the input from a wii nunchuck and then directly send step and direction signals (PWM) to the driver circuits that i'm using (Leadshine M542's). I've currently got the stepper signal outputs hooked up to LEDs until I have wired up the CNC electronics. I was wondering if anyone new whether the default 1 KHz PWM would be enough to move the motors around at any speed, or whether I would need to increase the frequency of the PWM output? I would test it but it's going to be a while until I can get the CNC controller up and running. Thanks in advance.
