I am building a custom CNC using servo motors for axis X,Y,Z but the tangential knife used for the 4th axis is a stepper. It will point the blade in the direction of travel based on the X,Y paths of travel.
My issue is getting a proper singal to the stepper driver. currently I am using the SMC_TRAFOV_GantryCutter3 function block which calculates the blade direction based on 360deg and puts that number into LREAL.
I am trying to find the best way, whether it be canopen or a pwm signal to move the knife in real-time based on the continuously changing degree variable.The blade will have to in either direction at any given time.
Any help is appreciated.
Thanks
