Pen Mount for the LowRider 4 CNC

Your CNC can be a very detailed plotter. You can use giant marker or ultra fine tipped gel pens.  The smaller the tip the slower you should move as not to burn out the tip. The wishbone suspension lets the pen move.  Smaller pens should have smaller preloads as well0.5mm works well for small pens, ball point pens are sloppy but more forgiving.

Play with your slicer settings and materials to get the mount arms as flexible or as stiff as you need it.
