Warning: Work in progress. Non-final version.
This design has been created for the Final Project of the Master's Degree in Teacher Training for Secondary Education, Baccalaureate, Vocational Training, and Language Teaching. The project is about an educational proposal consisting of the construction of a CNC plotter intended for students of the subject Technology and Engineering I in the 1st year of Baccalaureate (approximately 16-year-old students).
It uses an Arduino UNO, a CNC V3 Sheld, two drivers A4988 and a SG90 servo. Also, two old DVD drives are needed to get Steppers and other componets. I'll include a complete BOM.
The plotter uses a modified version of GRBL to control a servo and is operated with the Universal Gcode Sender program.

To be fixed:
- Improve the X rod fixation. Need to sacrifice 2 mm of run
- Mount capacitor filters on the endstops
- Improve stepper gears.
Improvements to add in v2:
- Adaptable rod brackets to allow easy custom rod lenght adjusting. This will improve the plotter reproduction with different DVD parts.
- Adaptable Stepper fixations
- X transmission system with GT2 belt instead of gears to show two different systems.
- Universal X carriage to allow easy tool replacement, b. ex. vinyl cutting blade.
- Adding a beer holder
