I came to use the machine this morning (Morning of Friday 7th June) and it has been left in very poor condition.
The nozzle was covered in black sticky stuff. The lens was coated in nasty sticky brown stuff, and the mirror was milky.
I’ve managed to clean the lens with multiple soakings and gentle cleaning with tissue over about 45 minutes - I have also cleaned the nozzle and the mirror.
I’ve checked with @Dermot and we agreed that I can now use, however there is a slight variation in the coating on the lens now, so can I ask an @lasertechs to inspect when you are able. You can only see the variation when held up to the light.
Photos of the mirror and lens (in the wrong order…).
