Adding An Offline Controller To My Omtech POLAR 350 & How Acrylic Engraving Can Destroy The Lens

This video is about adding an offline controller to my Polar and shows how I destroyed a lens by not properly maintaining it while engraving a bunch of clear acrylic. The controller is not something required for this laser but I wanted it for error messages, offline file processing, checking mirror alignment and manual focusing using a ramp test of the actual lens. I tried Omtech support for my problem this time and was surprised how fast they responded and solved my problem.


This is the controller I bought and Cloudray will most likely contact you to be sure you lust want the controller. Ships from China so it does take some time to receive https://amzn.to/40ETa6H
This is the super glue I use https://amzn.to/3XD56DY
