Electronics Feasibility Analysis

GRBL Feasibility

We set up an Arduino with GRBL on it. With GRBL, we were able to send motor commands in G-code to the Arduino. Using an oscilloscope, we measured the output of the Arduino. These signals would go the motor drivers which will drive the stepper motors.

Motor Signals

This output was captured from pins 2 (yellow) and 5 (blue) on the Arduino which represent the pulse and direction signals for axis X, respectively. The Arduino ran a command to move the X axis motor for a fraction of a second. The captured output shows the pulses sent to the motor, with the frequency representing motor tick speed.
