G-code to Electronics?

[S.R. Stoene]

Hello,
I'm in an E.E. Sr. Design Lab and we hope to build a 2-axis cnc machine as our project. My quesiton is how does G-code translate into electronics (IC, Micro-controller, PC)? Is there an industry-standard approach? S. Stoene

The NC (numeric controller) takes the g-code and converters it into pulses that, than get feed into the drivers that sends info to the stepper/servos.
(someone correct me if I'm wrong)

It's the other way round. The electronics is supposed to translate the G-Codes

G-Codes basically consist of movement (multiple axis) instruction as well switching instruction for spindle, coolant, etc. Your 'translator' will have to read the G-Code and electronically control the respective devices (stepper motor, servo, relays, etc)

Since you are in and E.E. Major you should check out the Open Source Controllers Forum. Check out the designs in there, they may give you a better understanding or starting point for learning how software translates g-code into pulses that the circuits translate into step and direction signals.
