Overview
Shield rev1 is an open-source printed circuit board by kosme, from the kosme/my_shapeoko repository on GitHub. It is a 2-layer board of 82.6 × 67.3 mm with 19 parts on 43 nets, routed with 142 tracks and 0 vias.
It is built around the MOC3011M. Its parts include 14 connectors, 2 resistors and 2 ICs.
Main components
1README
Upgrades/spindleControl/README.mdThis shield implements several hacks for my Shapeoko CNC.
- It disconnects the A-axis stepper motor signals. Now the source for that stepper are the Y-axis control signals. This enables to use a 2 motor Y-axis configuration.
- It connects pin 11 of the Arduino to an optocoupler to control the spindle speed and activity.
- It exposes pin 9, 10, and 12 so that they can be easily used to connect limit switches.
- It exposes all the analog pins for custom implementations.
- It provides a 5V and Gnd power rails to facilitate powering external accesories.
Atention
- The pinout it uses is based on the original Arduino Stepper Shield. This pinout was later changed so this may not work with your shield.
- It relies on a hack that connects the PWM signal for the spindle also to pin 12 on the Stepper Shield. This is not an elegant solution but does the trick since that pin is not connected to anything on the Stepper Shield.
All the files can be opened on Kicad 4+.

Questions
How big is the Shield rev1 PCB?
It measures 82.6 × 67.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Shield rev1 use?
19 parts, built around the MOC3011M. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Shield rev1 KiCad files?
From the kosme/my_shapeoko repository on GitHub, at the commit this page was made from: the board is Upgrades/spindleControl/shield_rev1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Shield rev1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask kosme before reusing the design.
