I bought a Chinese laser with a meenjet touch screen controller on board. I have spent time looking but I am finding no information. The board says L6 Plus which I can't find any info on. The normal L6 I see a little. It has a USB port and when the machine is turned on connected to a PC the on board controls don't start. It also looks like it has a connection for rotary but no way to control it with the on board controller. Ok the PC it shows up as a USB serial connection. I'd like to control the laser from my computer anyone have some advice? Or another place I should look for info? Thanks in advance.
