Good day. High school teacher here revisiting after may years. About to retire from teaching high school tech classes for 25 years. We have 2 Davinci Techno Servo CNC units sitting for a long time. If i do not take those they will end up in the dump and I cannot do that. So.......I am throwing this situation out here wondering if I can put the money and time into getting these up and going. If I get them going I might offer them back to the school if they want them back. I know from my last responses that there was a way to do this. Getting rid of that giant heavy original control box and replacing it. Appreciate the suggestions.
