Hey guys,
Thank you for being such a valuable resource. I have a 20w fiber laser from Wuhan Leadjet Technologies, the laser came with a built in control unit screen & operating system. Unfortunately, the system only lets you place very basic text. I wanted to know if there was anyway I could either put a new program on this device, or if there is a file type I can save to a usb that I can use another program to load onto there (ezcad maybe)?
Thus far, every time I tried to use a usb stick to load a file on the device, it does not load.
Thanks!
