I found a pdf from Boss Laser that details the wiring- so I don't anticipate any problems there. From the pdf it sounds like it will need a 320 config file to get me started? Or can I send a config file from RDworks, or is there a rudimentary file in the card that someone would be so kind as to send to me that I can modify for my machine? After struggling with Lasercut for a month and taking a look at RDworks... there is no comparison. I have worked with vector programs for 20 years and RD is pretty easy to understand and has many more settings (which could be a good thing?) The card from AliExpress arrives next week so I am trying to get my gooses in row. Thanks Gene
