i was cutting mdf no problem last night - then all of a sudden it stopped cutting and deceided to only burn the image onto the wood instead - no one was near the machine - it wasnt knocked in anyway it just changed what it was doing - i have checked water temp and water flow - all ok - no bubbles in tube - cleaned lens etc - now the tube fires up but noway near the power as it will not even pulse enough to burn paper so i can check alignment - i have to run the machine to get a scorch mark on paper directly out of the tube - i have rebooted machine still the same
has anyone had problems like this before or can point me in the right direction
many thanks
