Introduction: Drafting Robot With Adafruit Shield (Come through Move Contend)

Hello my names Jacob and I alive in the UK. In this project I am passing to build a robot that draws for you.

*I'm sure many of you privation to see it thus if you want to know please skip right to the moment to last step only be sure to retort here to see how I made IT*

I originally intended to design a mini 3d printer that could be man-portable and decamp a 12v barrage similar to this https://web.youtube.com/watch?v=vCUbUTh70UI . However, I didn't have the parts for it thus I had to improvise. I designed all of the 3d printed parts in tinkercad and to fit all my parts as some dvd drives are different to others. Lets get started!

Supplies

2x Old personal computer DVD drives that you don't mind destroying.

1x small servomechanism. I ill-used the SG90 servo.

1x arduino.

1x 3D printer. I've got an anet a8.

1x adafruit stepper drive driver shield. Non ARDUINO VERSION AS IT Single HAS SPACE FOR ONE High stepper MOTOR.

1x 9v battery or 12v psu.

Step 1: Ill-trea 1: Taking Apart Videodisc Drives.

I distinct to use of goods and services dvd drives as the motors because they work by having a small laser that moves close to systematic to write scarf ou on to the disk and read ( etching information). Also, this leave work on a very tight budget every bit they are found in everything. This process has to equal through precise carefully so it dosen't mess up. This is great for writing American Samoa IT needs to be very particular. I didn't get some pictures of taking it apart as I wasn't sure whether I was going to mail this. But all it involved was taking out the metal part inside that has the diminutive rails and a small stepper motor beside it.

Footprint 2: Step 2:3D Printing

I planned these parts so it would just slot on and then I could hot gum it. Please regard the entropy down below on how I designed these parts. There is a video recording up the peak of me designing a servo mount and then impression it.

Step 3: Y Axis vertebra Holder.

I designed a little holder in tinkercad that slot on to the dvd push laser chemical mechanism then you upright hot glue . Please excuse me for my sloppy hot glueing. This is actualy my first sentence using a mucilage gun the right way.

Step 4: X Axis Platform.

The first affair I studied was a thing that would slot on the the optical maser nurture it up so I would have clearance for the platform. Then I organized the political program its soul in tinker cad. This platform would just mucilage on to the Y axis raiser. I designed this with cheat holes for the motorial and with holes connected the sides to put the rail through. The last thing I studied was a thing for the laser to swoop done as this specific one didn't sustain two rails.

Step 5: Servo Pen Mechanism.

I have a colour diagram

Colour keys:

BLUE: servo

Purple/pink: Lever subdivision.

Orange: pencil.

Colorful: pencil holders one of which moves up and down.

Red: Holder arm

This is a precise simple actuator exploited quite commonly. I got the servo and the lever arm model off of thingiverse but everything else is designed by me.

All 3d prints and glueing are through now!.

Step 6: Build Shell.

I antimonopoly glued on a piece of wood and you can black and white and optional 40x40mm bed if you want.

Footmark 7: Motion! (Computer hardware)

For this I used an arduino uno and an adafruit shell. This should do the job as the arduino itself can control servos and the shield suports 2 stepper motors. To find out which cables to use on a motor you use a multi measure on the resistance function. This will tell you which Windings are which as when you put unrivalled cable and any other cable of the motor together if it's the proper Windings IT should have a resistance;IFnot, nix bequeath show. Wiring is ensiform just simply put the plus and minus for one winging in one side and the for the other. The servomechanical is even simpler as it just involves puting a connector on the shield board. I got my Dad to assist me with the bonding.

Step 8: Software and Firmware.

For microcode I utilized CNC code. For software I used Gctrl. I will capture a video erstwhile fully working. Thanks for version!.

Step 9: Done!

I still have tweaking to coiffure but mostly it's done!!!

Step 10: Improvements

Although this is, for the most set forth through with, there could be room for improvement...

I remember one matter I would make out is definatley change the motors to straitlaced stepper motors not rightful tiny ones without much torque. I would also change the moving system; instead of having a screw driven actuator, I'd have nigh axis belt driven. Last simply certainly not to the lowest degree, I would change the diam of the write out holders and the servo! This is important as it allows you to use any pen or pencil. THanks for reading 😃.
