Simple modification to pen holder

  • Here’s a simple modification to the pen holder to give spring loaded down pressure on pen via the servo. All it needs is a soft spring and a paper clip. Adjust the wire length so the spring has no tension at zero. Use servo values up tp 100 to increase down pressure on pen. Works a treat!


  • @mrbazza Hi ! I was wondering how you can change the servo values. In addition, is it possible to vary the pressure at different paths in the same drawing ? Nice setup !!! Thanks !!!
