Ever let the "magic smoke" out of a brand-new piece of hardware? Today on #PrintFix Friday, we’re joined by the legendary Danny from @NeoKoiPrints to talk about a catastrophic (and expensive) motherboard failure during his ambitious StealthChanger build.
Danny was upgrading his tool changer to a @bigtreetech5117 Kraken for those sweet 48V Z-axis speeds, but a tiny multimeter slip turned into a $130 spark-filled disaster. We’re breaking down exactly what happened, why the 5V rail went dark, and the "Game of Operation" you play every time you probe live electronics.
In this episode:
The moment the Kraken died (on 4K video!)
Diagnosing a StealthChanger with 6 tool heads.
How a mis-pinned Z-probe almost saved the day (until the multimeter came out).
