Your fiber laser isn't broken. Your setup is. Most "my fiber engraves like garbage" problems trace back to setup, not the source and not the software. The 6 steps I'd run on any new fiber: 1. Eyewear rated for 1064 nm (CO₂ glasses won't cut it) 2. Level bench, lens square to the work, extraction at the mark 3. Read your lens barrel, then match the software field size to it 4. Find true focus with a tilted-plate test 5. Engrave a square, measure it, correct scale + distortion 6. Test grid on every new material, save the winners 📋 Comment SETUP for the printable checklist!
