General Mach Discussion / understanding how mach process works.
« on: December 02, 2016, 01:39:02 PM »
Hello i am new to diy cnc and i was thinking of using mach but i wanted to under stand how it works before i go further. I have tried to research as much as i can but im stuck on some aspects. I have programmed other machines and do allot of tech work but without physically using mach im stuck. Any help would be appreciated.
1 obviously you put a gcode file from a cam software into mach, but how is the information sent to the stepper/servo controller? (in gcode or is it decoded into machine language or something)
2. at which point in the processes are the gcodes decoded into a usable signal for the steppers/servos?
3. is it a digital signal with packets being used throughout the machine or at somepoint does the machine use electrical pulses?
4. if servos are being used does the positioning feedback get sent to the servo controller or to mach?
Thank you guys allot i figure this would be easy questions for a seasoned diy machinist.
