thank you for your reply homepin, no it inst that board, the board in my machine has two sensors, it has a plastic lever that has two inserts that sit infront of the sensors when you push the button, im guessign that is type two? the boards on my machine are very clean, but i did get a bit of black shit on the cotton tip when i cleaned it, it seemed to make it work better, might just need more of a clean im guessing. but if you make these boards in the future ill keep an eye out and should be interested, especially if i cant get in there good enough to clean the lenses. cheers
