My gh1290 machine arrivde about a month ago supplied with the W2 RECI tube, but it packed up yesterday afternoon...so i am depressed at the moment. stopped lasering after it ran the whole day without issue, at mostly 65 % power cutting 3mm mdf. on investigation i found the laser tube completely filled up with water. so something cracked / broke inside the tube which caused this failure. in contact with Shenhui at the moment to understand how this could have happened.
Being a bit paranoid, i kept a eye on the cooling and it ran constantly around 19 degrees C so don't know what went wrong
