@donkjr - If you’re interested in taking a look at Lightburn let me know - I noticed that a few people have noted that it’s their principal interface now, so if you’re curious, either myself or Ray can give you access to the beta group.
I currently use a VendorID / ProductID system to identify boards, but the eventual plan is to allow you to just point me at a COM port and I’ll take your word for it. For now, this allows me to detect boards without a complicated UI or protocol vetting.
Current imports are AI, PDF, EPS, with DXF and SVG in the plan. Probably PLT and HPGL as well. I’ve never dug into a SketchUp file. Is the format documented? I’m open to supporting pretty much anything as long as people will use it.
