Hey everyone - finally finished one of my work projects and now trying to get back into the shed only to find my laser no longer likes me.
I noticed that a lot of the jobs I was trying to do needed more and more passes to achieve the same result and sometimes it just did not engrave at all.
I thought it might have been the mirrors or lens and as I have been using the stocks ones I ordered some new ones, they have not arrived yet.
Today I realised that when I turned the laser up over 3-4 mA it was just not firing anymore, could this be an issue with the pot? or more likely the tube?
