Yeah I agree, the problem could be as simple as they have not tried software with it which would obviously mean the cutting head wont move, but they are well cheap and I have to assume there is something wrong with them otherwise Im gonna buy them thinking I can fix them easy and it will cost me a lot of money. The guy doesn't know a lot about them and he is just trying to shift them asap. Apparently they have worked in the past and he said he hasn't set them up with software to try them he has only turned them on. Well if that is all he has done, then it wont do anything so Im hoping its his lack of knowledge.
The cutters are, Pcus but what model I dont know, Ill upload images
