LIGHTLY MODIFIED GRBL FORK FOR UNIPOLAR STEPPERS
01 / The build
Behind the project.
A 3018 CNC machine, and a firmware side-project: a modified fork of ruizivo/GRBL-28byj-48-Servo (itself built on robottini/grbl-servo) that extends 28BYJ-48 unipolar stepper support to the X, Y and Z axes, driven through ULN2003 boards on an Arduino Uno - used for a 2D plotter. A fork with light modifications, not original firmware development.
