Fiber Laser Upgrade for Your Diode Engraver? Atomstack MR20 Review

I am going to test the Atomstack MR20, a 20W fiber laser module upgrade for Atomstack diode laser engravers. With this fiber laser source you will be able to engrave all types of metals and some plastics too. It is a powerful true fiber laser source producing 1064nm infrared light which can also be used for laser cutting metal! I have mounted it on the Atomstack X30 (A30) Pro, but it fits older modules like Atomstack A10, A20 or X20 too. In this video I did some practical tests to see what it can do.
