I am familiar with Soulstan Inc. from many years ago when I upgraded my rotary engraving machine. Their new laser controller is based on the same principle using CorelDRAW or other CAD Programs print function. One of the many reasons I like this controller is because it's USB driven. The list price might seem rather steep but I negotiated a substantial discount :-)
I just got finished installing the Agni hardware/software a few days ago on my Chinese 50 W (a piece of no-name junk!) laser and everything seems to be working great when my hard drive crashed.
The reason I'm posting this, is because I would like to contact other users. Of course I could also be of help, I am an electronic technician by trade, retired. This controller is fairly new and there are not any postings of any kind that I can find, relating to it.
By the way don't the Chinese manufacturers put their name/contact information/model number etc. information on a label/tag anywhere on their machine?
Happy Lasering!
