Now I want to draw lines into the spiral to create 50-60 rectangles instead of having just one long one. So, at the end I would love to have 50-60 equal rectangles along the spiral. Any idea to construct theses?

LightBurn is not a drafting or drawing program, so you might be better off with one of the various programs suggested in a recent discussion about making machine cams:
