Open Source Pen Holder Toolhead
(Redirected from Pen Holder Toolhead)
Basics
- A device that allows secure attachment of a pen or marker to a CNC device such as a FDM 3D Printer
- Can be used as a PCB Plotter or as a basic printer for documents and drafting
- Main Designs:
- VERY simple: tape it to the fdm extruder toolhead
- Simple: 3d printed adapter holder with no pressure relief
- Standard: use rubber band or cheap slides etc to allow it to have some "give" to it preventing it from stabbing your printer, and making bed leveling easier
- Advanced: Add some sort of encoding mechanism (how "pressed in" is it), and/or a solenoid for pulsing it in high resolution dot matrix modes

- An Over-engineered (in a good way) holder allows for slight spring like movement in the z axis (to smooth "bumps" etc) they used a rubber band, perhaps use a spring?.
- A Video of A Solenoid Including Design no shown use for dot matrix use, also noise suggests poor optimiazation (hitting edge, ie too powerful/not timed right etc)
- A Video by the YouTube Channel "René Jurack" Titled "E3D-Toolchanger - Pen Tool" (They designed a toolhead for the E3D Toolchanger with a Compliant Mechanism inside a larger bore cylinder mount as the method for gripping the pen/marker etc, which should make it work well with just about anything)
