Sorry, I broke the laser cutter this morning. The lens holder had been done up so tight I physically wasnt able to undo it to check the lens. I only had a quick cut to do so thought it would be alright. But unfortunately the lens must have been dirty and has over heated and melted the lens holder. I’m not sure if the lens itself is reusable as it has a bit of melted plastic on it.
I have put a note on the machine saying lasercutter our of action. And placed the lens and melted lens holder on the ledge above.
