Hi, I am a 66 yo senior citizen who has had a life long passion for making things, mainly RC scale model steam boats and warships and model steam engines. I own a small lathe and a small milling machine. After recently dragging myself into the 21st century, I now also own a Monoprice 3D printer, an Elegoo Mars Pro resin 3D printer a Vigotech 20Watt laser cutter and engraver and an OX CNC Router. I have managed to integrate 3D printing with my model engineering activities by using the 3D printer to make foundry patterns. I am keen to learn more about the use of these wonderful machines…
