Was making some brackets to hold solar lights around pool fence which was going super well and got a few done
but then cuts stopped penetrating 3mm MDF like usual.
Slowed the cutting down heaps and still no luck so went to recalibrate and barely marking paper. Time for a deep clean I thought. But and as soon as I saw lens… Oh No! Dreaded lens burn. no wonder not cutting anymore.
Upon closer inspection, also noticed quite a few artefacts near the outer margin of lens too.
worst thing is, is’s a rainy day and cant muck about on laser today.
