3D Printed Parts

Cut your Linear Rods

Use a measuring tape and sharpie to mark the spots where the rods need to be cut

• Use a vise to hold the rods in place when you cut them
• Remember that you need (2) 350mm and (2) 450mm long linear rods
• On the threaded rod, mark your cutting point at 470mm

Assemble the X-Axis (Linear/Threaded Rods)

Take the (2) 450mm linear rods and insert them into either x-support part

• Use may need to use a round file to smooth out the holes that you insert them in
• Also, you can use a rubber mallet to help insert the rods

Now take the threaded rod and insert it in the hole below. Feed a 5/16in washer and 5/16in nut on both sides of the x-support part

Assemble the X-Axis (Bearings)

Now you want to push the LM8UU bearings into their place on the top and bottom clamshell (The top and bottom clamshell take (4) bearings each)

Take (4) 624zz bearings and push them through the 3D-printed idler pulleys. Leave the 5th bearing for later when you assemble the Y-axis

Assemble the X-Axis (Carriage)

• Get (4) M3-0.5 x 20mm screws, (4) M3 nuts, (4) M3 washers and (4) 624zz bearings with the idler pulleys installed
• Take one screw and feed a washer through it, the washer will rest on the bearing. The nut will be at the bottom of the carriage, which will secure the bearing in place

Assemble the X-Axis (X-Support)

• Slide the clamshell through the 450mm (X-axis) linear rods
• Use a rubber mallet again to attach the last X-support on the linear rods
• Make sure that the rods stick out equally on both sides
• Slide the other end of the threaded rod through the hole on the X-support
• Put on the last set of nuts and washers to hold the X-support in place
• Now that the X-axis is complete, you can use (2) Phillips M3-0.5 x 16mm screws per X-support to help keep the linear rods from sliding

Assemble the X-Axis (Stepper Motors)

• Use an appropriate sized allen wrench to attach the 16 teeth pulleys on the stepper motor shafts
• Flipping the entire chassis around will make it easier to attach the stepper motors
• Use (8) M3-0.5 x 6mm screws and a Phillips screwdriver to attach the (2) stepper motors

Assemble the Y-Axis (Clamshell)

(Optional if you have problems keeping belt on bearings)

• Grab (4) M4-0.5 x 35mm screws and (4) M4 nuts
• Make sure that you have the (4) idler pulleys ( Download from Thingiversa ) and the (4) washers printed
• Insert the washers in between the two clamshells, with a screw in between
• Screw the top and bottom clamshells together

Assemble the Y-Axis (Y- Back/Front)

• Take the (2) 350mm linear rods and insert them the Y-back piece by using a rubber mallet
• Get (1) M4-0.5 x 35 screw, (1) M4 nut and the 5th 624zz bearing
• Get (2) M3-0.5 x 16 screws to secure the linear rods
• Slide in the bearing when inserting the screw through the Y-back piece
• Slide the the linear rods/Y-back piece through the LM8UU bearings and attach the Y-front piece using a rubber mallet

Assemble the X-Y Axis (Belt)

• Use a pair of needle nose pliers to help guide the GT2 belt more easily through the clamshell
• Take the two ends of the belt and slide them through the “teeth” on the Base Slider
• The belt should be tight and not loose
• Note that once the GT2 belt is on, it is normal for the clamshell not to move easily

Belt Diagram

Assemble the Z-Axis

• Get (2) 3mm linear rods and the following 3D printed parts (Slider, Pen Holder, Base Slide, 3MM Metric Thumb Screw)
• Get (1) Hex M3-0.5 x 20mm screw and the Metric Thumb Screw and push them together. Use superglue to keep it together.
• Get (3) M3-0.5 x 16mm screws which you will use the secure the Base Slide to the Y-Front part. You may need to use (3) M3-0.5 nuts in order to hold it in place
• Push the Slider and Pen Holder together to make one piece
• Now take that new part and the (2) 3mm linear rods and slide the rods through the holes. Place a small spring in between the two parts so there is a little bit of pressure to lift the Slider. You may need to cut the spring a bit until there is an adequate amount of pressure on the slider.

i constructed all the machine but when i press X+ the both X and Y axis are moving what is the problem

double check the steppers wiring

Have you solved it? I have the same problem with my machine, when I press X+, it’s necessary both motors move at same time, but, only one of them move…

Did you solve this problem?

Same problem how to solve ,?

Is it true that you didn’t use the microswitches in the final design?

Hello how to co figurę this machine to RUN on GRBL. What I mean is that GRBL interprets commands for x axis and y axis independently and if I look on your belt diagram it looks like both Motors have to run at the same time in order to move the carriage along y axis… How did you do that?

Have you solved it?

Thank you, thank you. It’s a very good built.

Is it possible to modify it to draw using brush ang oil based paint ?

Could you please tell what software/plug in and which version do you use to generate g-code for this machine?

Hello, what is the width of your belt? 6mm or 10mm? Thanks!

Drawing Robot/Pen Plotter/Drawing Machine is an Open Hardware version of the famous machine AxiDraw which it is a pen plotter, capable of writing or drawing on almost any flat surface. It can write with pens, permanent markers, pencils, and other writing implements to handle an endless variety of applications.

Its unique design features a writing head that extends beyond the machine, making it possible to draw on objects bigger than the machine itself. The biggest advantage of the machine is that it can be placed over the book because of the core XY extending design of the machine.

This Drawing Robot/Pen Plotter/Drawing Machine is similar to the commercially available AxiDraw. It is powered by an Arduino Uno controller, uses a CNC Shield, and GRBL firmware

The cost to build the Drawing Robot is between $75 depending on where you buy your parts and whether you already own some of the parts such as the Arduino.

ELECTRONICS

I prefer you can use Arduino uno CNC Shield

Ready to your all circuit

1) 4pcs A4988 Stepper Motor Driver

2) Expansion Board A4988 Driver

3)Arduino UNO First of all take hit sink and stick on A4988 motor Driver.

4pcs A4988 Stepper motor driver connect on expansion board A4988 driver module, then connect the arduino with expansion board and connect all wiring The shield also has a built-in micro stepping control - meaning that instead of using full steps or half steps like a large CNC would do, we can make the motors move by 1/16 or 1/32 of a step to make the laser move with the maximal precision possible. However, the motors will consume more electricity: they will get hot quicker.

To use the micro stepping modes, short some of the mode pins together. Different combinations give different resolutions. Take a look at the chart for the different configurations possible. When the shield is programmed, add the A4988 drivers to it and wire up the rest of the electronics.

To find the coils of the stepper motors, use a multimeter. If there's resistance between the two wires, you have a coil. On the schematic, the coils are represented by two wires of the same color.

This homework writing machine project features a DIY writing machine that uses a typical pen. It can do outline writing and digital signature or even a real text. The main system uses a 2 axis stepper motor driver board with Nema stepper motors and Mg90S Metal Gear Servo control.

The 2 axis stepper motor driver board serves as the main controller. It organizes the motor drivers connection that best fit for the writing machine operation. This writing machine uses threaded rod rotated by nema 17 stepper motors for X-axis and Y-axis movements on the surface, while a Mg90S metal gear servo is used in the pen stand that moves the pen perpendicular to the writing surface. The movements of the motor are synchronized and quite accurate provided that it is assisted by a well-made writing machine frame structure with mixed of wood and acrylic materials.

This project is suitable for embedded development hence it can accomplished digital writing activity. It is also a good reference for DIY text and figure printing provided that it can draw specific figures.

• Rumpel631 2023-11-27 08:39:52 Thanks for your comments and your suggestions. Over the summer I kept on checking, and the discrepancy was still present until ~9:30a, but overall it's not that bad, as the unaccounted energy balance over almost one year is about 1% on my system. Checking right now (9:25a local time) it's actually bad: ~240W (reported) solar production, ~730W usage (including 240W unexplained balance), ~500W net usage. So, the solar production number seems to be off by 50%... I think I'll leave it as it is, given that the overall effect is small....

• Johnben 2023-11-24 03:00:21 The discrepancy in your PV system's power readings during the morning hours could be attributed to various factors. One possible explanation is the initial startup phase of the solar panels. When the PV production begins at 8:00, there might be transient effects or fluctuations that cause a momentary imbalance in the power readings. This could be related to temperature changes affecting the Current Transformers (CT) readings. The temperature drop overnight to 15°C and the subsequent furnace kick-in at 8:00 could influence the CT readings, especially if there's a sudden change in electrical characteristics. It's worth investigating if the CTs are...

• sekemiat ke 2023-10-23 02:24:12 Three solutions exist to any intermittency in electricity distribution. One is ramping the production from the baseload generators to the point that it matches the demand. Secondly, use the secondary dispatchable generators to match the supply to peak demand over short timescales. Third, store the surplus energy during the peak production ties and use it during low production. If you follow the above three methods, you will have eliminated, if not reduced, the levels of intermittency in your power systems....

Simple Easy Homework Machine

Introduction: Simple Easy Homework Machine

This machine is built using cheap materials and doesn't cross 7$ to build. To build this you need some patience and 2hours of time. And you must be familiar with soldering and wiring since this involves a small circuit. Once it is built just plug in this device to your computer and run the required content to be written and it will start the job in no time. This I have called writing machine since it uses a pen to write the things. So let's build your own writing machine.

Step 1: Things Gathering

You need following things. 1. arduino nano. x1 2. L293D IC with Base connectors. x2 3. PCB board. x1 4. Computer DVD writers. x2 5. Some hard cardboard boxes. 6. 1ft.X1ft. plastic or wooden or metallic board. 7. Some wires. 8. soldering iron and wire. 9. Some male and female headers. 10. USB cable for arduino. 11. A pen with a strong string or thread which is flexible. 12. A micro 9g tower pro servo motor.

Step 2: Building X and Y Axis Carriages

Take out the stepper Motor from dvd writer as in the picture. You need to open 2 dvd writers carefully without damaging anything inside it. Screw one carriage which contained the stepper motor to the 1ft.x1ft. board, this is the X-axis motor carriage. Keep some gap for Y axis motor carriage to be placed . Left most side of the X-axis carriage stick a cardboard box as in picture and make a long slot at the bottom of the box so that x axis carriage plate can go inside the box. stick a plastic rectangular board to x axis carriage as in image which supports the paper to be placed on it.

Step 3: Circuit Building Process

Place the female headers on PCB board according to the number of pins on either sides of arduino and trim excess and solder that female headers to the one side of the PCB board. and also solder the IC bases to the same board. And solder the wires wherever required by looking into the above circuit image. and solder 3 pins of male header to the same board to facilitate the servo connection to be plugged and unplugged easily.

Step 4: Finalizing and Start Writing the Things

You can make this device write the things of your choice only after writing the gcode. Don't worry about gcode much,. since we are going to use a software to convert the required image or text into .gcode file, and then streaming the .gcode file using another software called Processing. I will give the direct links to download the Processing and Ink-space software so that you can crete your own .gcode files and stream whenever you wish. And the arduino code which you need to upload to your arduino board once and for all. DOWNLOAD EVERYTHING IN A .rar FORMAT
