Electronics Feasibility Analysis
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.
Arduino Uno loaded with GRBL
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.
