In this page I will collect and describe useful links that possibly help me to my target.

Mechanics

Using fishing line to move the axis, refer to: PrintBQ

Theme: some about fishing braid

Theme: Wolf Bot

Theme: RichRap awsome printer

Motions

As explained in the Project Note page I will use CoreXY as kinematics

Theme: new corexy twist

Electronics

Pighixxx Pinout of most used atmega board and chips

Starting form the beautiful MTM project, I want to make a similar circuit board that possible to drive by Inkscape. To do this I need to make 2 modules, one for the basic configuration with 2 stepper driver and 2 RC servos, and another one like a modular stepper board with one stepper driver and one RC servo.

I'm thinking about using a scheme like this:



The boards will be like Gestalt Node but the communication with arduino will be via ISP or I2C

Programming

The big gap is the software, Gestalt Node uses own software wrote in python, but my things is to use Inkscape to drive the machine. In order to do this I decided to study around Inkscape plugins developing.

Searching about plugins i discovered a plugin used for the Eggbot machine, is a beautiful plugin that allow to drive a simple cartesian bot with a tool like a pen. One problem about this plugin is that the eggbot board have a PIC microprocessor instead Atmega that I want, so I will take inspiration on this plugin and I will rewrite to send a normal GCode.

The Eggbot project fortunately is well documented Eggbot on Github

and: Eggbot plugin description

Inskape have already other nice plugins to convert SVG to gcode like: Gcode Tools

Another ispirational maybe is this Spherebot project

To write a new inkscape plugins i will follow these links Inkscape forum

and Inkscape wiki

Using these library pycam
