Hi guys,
Just today in the morning I was trying to cut 6mm MDF and noticed that it could not be cut at my normal speed. I checked each power supply and noticed that both of them have power LED on but only one has its laser LED ON(halfway when it is not firing and full when it is firing) When laser is firing only one PS shows 32mA(the limit we set up with resistors) and the other one shows 0. They should both show 32mA.
Tried to swap control cables: The working PS still worked after swapping but for some reason the laser fired on initialization without pressing any fire button. The one that seems to be faulty still did not work after swapping.
Tried to swap HV cables: The working one still worked, the faulty did not.
Then I found this video https://www.youtube.com/watch?v=WRWCPxQlGPs They do some PS testing with a test button. Checked on mine. The working PS was firing and its laser LED goes full ON after pressing the test button. The faulty one did not react to pressing the test. Its laser LED is always off.
Do you think it is a PS fault?
P.S. This is for the machine with DLT-300 Yongli tube. It has two combined tubes in a metal case and that why it has two power supplies. Everything worked just yesterday and for more than a month. I cannot inspect the tubes because they are sealed with warranty stickers.
