The file 'DrawingBot With Improved Head And Rotate Pen (for Fountain Pen) 3D Printer Model' is (stl) file type, size is 281.9KB.

Summary

Based on DrawingBot by MakerC, with 5 new 3D/STL files that you can use to add improved slider stability for the head, including pen-tilt. You can set the rotation in 3 variations (straight / 25 degrees / 50 degrees).

In this build I've used a servo (MC-375DD), which has a slightly longer shaft section.

Parts used to build:

  • 2x stepper motors (SY42STH47-1684A)
  • 1x Arduino Uno board with Arduino CNC shield
  • 2x Pololu A4988 stepper driver (with jumpers @ 4x microstepping)
  • GT2 timing belt (2 meter) + 2x GT2 20 teeth
  • 4x Micro switches on all axis (used as normally open)
  • 1x Servo motor: Modelcraft MC-375DD

  • Spring (custom), this gives just enough force to put pressure on the pen on the paper/surface (like with actual writing by your hand)
  • All other screws/parts/rods/bearings as listed in the original thing

Arduino code: (compiled and uploaded using the Arduino IDE; make sure to update config.h in your /Arduino/libraries/grbl folder to enable CoreXY !!!)
[More info on CoreXY here: http://corexy.com/theory.html]

Next STL upgrade to come: carrier that can rotate and lock for a fountain pen (45c angle)
