Building the CNC Data Validation Layer (Node-RED + n8n + Express.js)

In CNC monitoring, raw machine signals are unreliable. Spikes, unstable transitions, timestamp errors, and missing fields can break your analytics — especially OEE. So in Blog #11, I explain how I built a full CNC Data Validation Layer that cleans an...
