Hi!! I have a doubt... My friend told me I can never disconnect a stepper motor when it’s driver (in my case the Gecko G540) is turned on. That I may fry the driver...
While assembling my cnc kit to my mill I often connected and disconnected a stepper, for testing reasons,and sometimes the Gecko was turned on through Mach3. I never experienced any problems, but now I’m afraid I could fry my controller.
I really can’t disconnect the stepper from the gecko while the gecko is on? (On, but the motor is not running, of course)
Could I fry it? Or the Gecko has some kind of protection against it?
