Hi all, i've built an interface board using tweaky.cnc little ESC board , i even bought the pic programmer and so far i'm getting some sort of success. it seem's the PWM input frequency used for Mach 3 is different than that of the one for the arduino uno controller. and running GRBL ver 1.1 My question is, is it possible tho change the internal routine of the pic 12683 microcontoller so that the input frequency is compatible with the ESC the minimum pulse width has to be between 1.0us and 2.0 us for full speed. All i Have is the hex file used for programming the pic. Anybody out there worked on that Project!. Any help would be appreciated. Thanks
