Dummy Stepper Driver
thingiverse
To design my own printer electronics, I tested all connections to ensure proper functioning up to the stepper drivers. Utilizing 10k 608 SMD resistors and LEDs from TV remotes and cell phones, I created a compact setup with resistors on the same pad as pins for space-saving. The LEDs indicate power for motors, driver power, stepper setup, enable status, and pulse/direction. This tool proved useful in diagnosing both software and hardware issues. Two PDF files are available: one for transparency/photosensitive boards and another for toner transfer method. I have successfully used these boards in my 3D printer and CNC machine projects, finding them highly effective.
