The guys dive into one of the wildest “why does this even exist?” releases yet — a massive 4×8-foot hybrid diode/CNC machine from ER that’s equal parts intriguing and absurd. They break down why multi-purpose machines rarely excel at any one task, how scale turns convenience into chaos, and what kind of maker could actually use something that big. That leads into a grounded comparison with the new Monport Reno 65 W CO₂ laser Alex just uncrated - a reminder that sometimes “simple and fixable” beats “feature-stuffed and fragile.” Along the way: real-world CO₂ vs diode fire safety, frame rigidity, Kickstarter red flags, and a few laughs about girthy gear, winches, and cabinet engraving no one asked for.
Learn to Laser Everything™ with new episodes of the Laser Source Podcast EVERY WEEK. We cover laser parameters, settings, techniques and more for CO2, Fiber, Diode and UV Lasers! We believe in free and open maker resources. Check out some of ours below:
