Hello
In the first place, please excuse my bad english.
I work with an Epilog Laser 75W but I have some questions about this machine. In the first place I have problems with the laser tube coolers. Two coolers don't want to work, after some tests I discovered that on the connection cables (from source to coolers) is inserted a diode. The question is : what type is this diode and why is necesary ?
Thank you
