I am needing a cnc plasma cutter about 2'x2' for cutting 16ga. I found GoTorch, but it does not seem to work on Windows10 or any modern computer. I tried to contact them with 2 questions and they never replied. Someone else told me they don't even take new orders, but perhaps that was a payment method mis-understanding. idk. So what alternatives are there? There must be some open source kit that rivals it. Suggestions?
