Does anyone know of a pen attachment for a cnc. I wanted to plot some things but you cant get plotters anymore. I have tried various pens but unless its spring loaded its hard to get the correct tension on the point.
If its pressing too tight you get little wiggly lines as the pen constantly deforms. If its too loose you get good lines but fails to make contact in most cases. If it were spring loaded then that could always keep the proper ammount of pressure of the pen against the surface.
Color is not an issue I just need to draw some fine lines in black
