• Printed all the parts with 0.10 – 0.20 mm layer height
• Printed with Hatchbox Red PLA
• Use supports on the Penholder, Slider, X_Support_L and the X_Support_R

Note: The longest part took around 9hrs and the shortest took 30 minutes to print

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!

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.

• forlinxembedded 2024-03-21 04:05:55 Hello Erdem, It's interesting to learn about the differences in electric pole usage between countries. In many countries, wooden poles are commonly used due to their availability, cost-effectiveness, and ease of installation. However, in regions with higher load requirements like Turkey, stronger poles are necessary to support the infrastructure. In the USA and some European countries, wooden poles are reinforced and treated to withstand the required loads. Additionally, alternative materials like steel and concrete are also used for electric poles in various applications. If you're interested in learning more about electric pole types and standards in different countries, I recommend...

You don't say what DC voltage you need, the voltage you would get from directly applying the mains to a bridge rectifier were typically used, for example, to supply the input to a flyback switch mode power supply, where the switching transformer provides mains isolation. The voltage would typically be around 300V DC, and the rectifier and capacitors have to be rated for that voltage plus a safety factor. I assume that you are needing a low voltage DC, since you have 25Vdc capacitors...

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.

Download the files from Thingiverse

Open the 3D models in Cura or any other slicer.

Use 75% infill on all the parts (An infill of 70 – 100% will work as well)

Printed all the parts with 0.10 – 0.20 mm layer height

Printed with PLA

Use supports on the Penholder, Slider, X_Support_L and the X_Support_R

Note: The longest part took around 10hrs and the shortest took 30 minutes to print

PLA is fine for this design. I print at 200C on BuildTak. None of the parts require rafts or brims. I suggest supports only for the pen holder and the Z axis end plate which is standing up.

Remember that you need (2) 350mm and (2) 450mm long linear 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

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

• 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

Step 6: 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
• 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.

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.

• The Arrival of the Homework Machine

By spring of 2023, most students with an internet connection had access to a new tool that could do much of their homework. We hear Justin’s keynote at the Connecticut Association of Boards of Education about the arrival of generative AI in schools, from last fall. Then, Justin talks to Jesse Dukes about an ongoing TSL research project to understand teachers’, school leaders’, and students’ experiences of generative AI in schools.

Justin spoke at the Connecticut Association of Boards of Education in November of 2023. You can see his graphics and outline . tsl.mit.edu/AI/ has more generative AI related resources, including our SURVEY for educators , school leaders, students, and parents. Jesse Dukes is leading our current project about the experiences of teachers and students with generative AI this school year.

Homework Machine

Introduction: Homework Machine

The homework machine is an interactive tool to collect homework. It's a machine that stands in a class room. The kids can put there homework into the mouth of the machine. The kids have to do some teamwork, some of them operate the inside of the machine and others are watching thrue the window to guide the homework into the right direction. The homework can end in 1 of the 4 compartments with there own achievements. The homework machine is a stimulating and a fun way to make homework and collect it.

Step 1: Body Base Plate

1) Used materials :

• MDF (A) : base plate 900*500*15 mm
• MDF (B) : 3 shelfs 500*170*15 mm
• MDF (C): beam 40*500*15 mm
• Wood connectors
• Nuts and bolts

3) Saw a corner off :

• MDF (B) : 15*40 mm => 15 mm in width, 40 mm in length of 1 corner.
• Apply this step for all 3 pieces

4) Construct :

• Screw and glue MDF (C) on 1 side of the base plate MDF (A)
• Line out the MDF (B) shelfs over the length of the base plate MDF (A). A schelf on every 22.5 cm.
• Screw and glue the shelfs (B)
• Reinforce the shelfs with wood connectors to the base plate (A)
• Attach the wheels to the plate ( 80*80 mm from corner)

Step 2: Right Body Plate (wood)

1) Used materials:

• MDF 100 x 120 x 1,5 CM
• Drill 46 mm & 32 mm

3) Saw the right body plate:

• MDF, saw the right body plate in the next dimensions: Height base plate – highest peak = 100 CM Height start mouth till base plate 70 CM, distance to rear end 120 CM Height back 75 CM

4) Drilling 3 holes:

• Drilling 3 holes of 46 mm at the top of the plate. measured from the bottom right, straight up and then sideways. See the picture above.

5) Drilling 6 holes:

• Drilling the 6 other holes of 32 mm in the plate. measured from the bottom right, straight up and then sideways. Distance B-C = 13, distance A-b = 9. See the picture above.

6) Saw the 4 doors:

• Line out the 4 doors on the bottom line. 16 x 16 CM.
• Screw them back in with hinges.

Step 3: Left Body Plate (perspex)

3) Saw the left body plate:

• Saw the right body plate in the next dimensions:

Height base plate – highest peak = 100 CM

Height start mouth till base plate 70 CM, distance to rear end 120 CM

Height back 75 CM

The same as in step 2.

Step 4: Front Plate (wood)

• MDF 530 mm * 790 mm * 15 mm
• MDF 60 mm * 740 mm * 15 mm

3) Saw the MDF plates in the right dimensions.

Step 5: Polygonal Holders (right)

• 4 x MDF (100mm*100mm*15mm)

3) Saw 3 polygonal holders with in the middle a hole diameter 46 mm and 1 with diameter 32 mm.

The holders are in the places where you can not rotate the axes.

Step 6: Polygonal Holders (left)

• 12 x MDF (100mm*100mm*15mm)

3) Saw 6 polygonal holders with in the middle a hole diameter 46 mm.

Saw 6 polygonal holders with in the middle a hole diameter 32 mm.

Wherever there are holes or holders placed at the right side, there are holders placed with the same dimensions on the left perspex side.

Attach the holders with screws to the perspex.

Step 7: Hollow Profiles for Peripherals

1) Used Materials:

• 4 x insulation foam (or others)
• Contact glue

3) Cut off 3 pieces (length = 200 mm and a diameter of 80 mm)

Glue the profiles onto the perspex side and the MDF side at the correct dimensions.

Step 8: Axes

• 3 wooden cylinders (length = 540 mm and diameter 40 mm)
• 3 wooden cylinders (length = 500 mm and diameter 40 mm)
• 5 wooden cylinders (length = 650 mm and diameter 25mm)
• 1 wooden cylinder (length = 500 mm and diameter 25mm)
• The axes can be covered witch all kinds of materials: we use a paint roller, gloves, insulation foam and a wooden plate.

3) The foam, paint roller, gloves, PVC and the wooden plate are glued or screwed to the axes.

Step 9: Handle Wheel

• 3 x MDF plate 250mm*250mm*15mm
• Standard wooden handle

3) Make a circle witch a diameter 220 mm. Use a saw and a sander to become the correct dimensions of the circle.

Screw the handle to the circle.

Step 10: Teeth and Tongue

• MDF plate 520mm*110mm*8mm
• MDF plate 520mm*100mm*8mm
• Flexible foam

3) Saw the shape of the teeth out of the MDF plate. (see image for dimensions)

Finisch with sandpaper.

Cut out a tongue from the flexibel foam by using a box cutter.

Glue the tongue to the lower teeth.

Step 11: Assemble Body

2) Screw and glue the left body plate(perspex)and the right body plate (MDF) to the base plate.

Screw the front plate to the left, right and base plate.

Step 12: Assemble Other Components

2) The axes are disposed between the holders and thrue the holes. (blue on the image)

The wheels are screwed and glued to the axes of the conveyors. (green on the image)

The teeth are screwed and glued to the body (yellow on the image)

Step 13: Conveyors

The conveyor belts are tensioned between the thickest axes.

We use bicycle tires as conveyor belts.

Step 14: Make Back

We stretch an orange rope between the two sides as reinforcement.

On the ropes we put a cardboard.
