so, instead 0-5V do i need use rpm of encoder? 0rpm =0feed 200 rpm =100%feed or something like that i know software -Go To meeting--- remote computer can use - take control of your mouse - if that possible than it will be possible to use those mouse to control scroll bar for feed on emc2 monitor and move it left to right.
i think be better use 0-5v to control. a lot problem may happen with encoder - motor etc use USB and some how plug into emc2 to control feed will be best without of use axis channel. is this possible ?
