I’ve currently got my laser setup and trying to get it calibrated. I’m pretty sure I have everything configured properly. Just need to work out the g-code output. But I had a question about the focus of the 3 glass lens. I have my laser mount about 55mm from the object I’m burning. I have the lens adjusted very far out to where theres little thread left to extend it any further. With that said, how focused does the laser beam need to be? Am I trying to get the smallest beam possible? When set to full power (255), I’m assuming I want it to burn at a fast rate? Any suggestions on tuning are welcome! Thanks!
