Big Red Version 1

Here is a little about what i plan to accomplish with this machine. I am hoping to end up with a 5 Axis CNC machine that i can change the head to a 3d printer head and have a cutting area of about 1300mm x 1000mm x 240mm.

i will first build a 3 Axis Gantry CNC with hand cut 18mm MDF and then use that machine to cut better quality parts in the hope that a can start to machine aluminium. Then if all goes to plan start making aluminium frame work and build it up to a 5 Axis CNC.

One that is phase is complete i will move onto building the stand along control panel and motion controller using a combo of AVR, Ardunio and TI Stellaris Arm Micro controllers which i hope to use to make a closed loop system using some AS5048A magnetic rotary encoders on each stepper motor shaft. From there i will start work on accessories like auto tool changers, 3D digitizers and all the other fun stuff.

i am still looking for any other parts people could donate like sheets of Plastics ie delrin, hdpe or aluminium that would be great even old machines that i can salvage buttons, electrical and mechanical parts from would be great.

The geek will inherit the earth. 🙂
