Another customer just posted his pictures of a home switch installation. In the regular setup for both Patriot VFD and Mill Turn machines, the spindle sensors use 2 of the Gecko inputs, leaving only 2 unused and available for things like home/limit switches. There is a simple way to free up one of the inputs on the Gecko so the spindles both connect to a single input port, leaving 3 available. It only requires a switch which we have in stock and some very simple wiring. Attached is a file on how to make the change.
