11. Open Source Hardware - From Fibers to Fabric¶

Research & Inspiration¶

Machine Hacking¶

What does this mean? It’s when your machine — CNC, 3D printer, laser cutter, or anything else — works only with a closed program, and you can’t change anything inside it. Sometimes the machine is so old that the official app doesn’t even work anymore.

Machine hacking is also called machine outsourcing. The idea is simple: the machine is locked, closed, stubborn — and you hack it to make it open, flexible, and more powerful.

It’s like taking your printer and saying:

“Okay honey, stop being dramatic. I’ll change your brain, your habits, and now you work with me.”

That’s machine hacking.

It is very common for:

3D printers
CNC routers
Laser cutters
Game consoles
Old machines with locked firmware

What Actually Happens?

What you must do when you want to change the electronics

You remove the company’s locked motherboard and just put an open-source motherboard, for example SKR, RAMPS, Duet, or anything else. After this, the machine can be used in a more common way, you can make changes and work without forced programs.

The firmware change

Closed firmware → open firmware (Marlin/Klipper). Now you can edit all settings: speeds, sensors, everything.

Removing the company’s limitations

Many machines block:

third-party parts
other filaments
normal G-code
custom extruders
Machine hacking cuts all that out.
Make the machine repairable and modifiable

You can upgrade motors, add sensors, install new hotends, fix things by yourself, or do anything else. We have total freedom!

Now, freedom in everything may seem unreal, but having more space and control over your own machine, which becomes your work partner, is really a good decision — a bit of air outside the stupid program jail.

Why Should Manufacturers Buy CNC Machines Over Outsourcing?

MakerBot Replicator 2 HACKING¶

Which Printer And Problems We Have¶

We have two MakerBot Replicator 2 printers that are already more than ten years old. They haven’t been used for years — not for printing, not for anything. Now, together with Anush Arshakyan, we are trying to revive them and turn them into an open-source heating machine.

The beautiful MakerBot photos — doesn’t it look really good?

Why do we need to make it open-source?

In the research part I already spoke about the huge problems that come with using a machine that works only with closed programs — and MakerBot is exactly this type. Because our printer is an old version, its official software doesn’t work normally anymore. At the beginning we tried to use its original program to do the heating process, but it was almost impossible.

For testing, I made a small 3D line object.

The object is a very interesting animal line sketch which I have from Pinterest. It is rhinoceros. And the fun fact is that rhinoceros I made with Rhino 7 program >< and slice it with MakerBot print program.

The sketch inspiration came from this sketch.

Rhinocer by lil11.barseghyan on Sketchfab

And make it's 3d version but changes some little parts and changes the sketch more like for soft robotics. thich tools i used you can cheak in my previous weeks.

3d resalt ⬇

Then I exported it as an STL file, and after that, we had to import it into the MakerBot printer program.

It was easy to download, but really hard to sign up in the app. How it worked like that, I really don’t know. After a lot of hard work, we managed to download it, but it did nothing. That’s when we understood that the program doesn’t work with this app—the versions were too different. Then we found an older version of the app, recreated the code, and this is what we got after that.

What resalt we have.

And the question: what is this? It is not what we want to do. We changed a lot of parameters and sketches, made it again and again, but nothing changed until we understood how it draws. It made our sketch fast while the transportation lines were slow, so the vinyl touches in the transportation lines but not on the main sketch.

But this part is impossible to change — we did everything, yet it keeps drawing the same pattern again and again. After long experiments, we decided to reset its program and download the open-source version.

Nozzle Head Tearing¶

Because for the heating parts we needed more curved heads, we thought about going to ironworks, but decided to spend all that time on machine coding and working with them. Mkhitar Evoyan helped us sharpen the nozzle head in the lab using his own machine, which he made during one of the Fab Academy weeks. It is a very simple system: just rolling the head and sharpening the edge with two tools — a hard one and a soft one for grinding.

Footage from the process.

And what the resalt we have ⬇

More about this process you can find in Mariam's documentation. She is one of our participants and a very interesting person with great ideas. I think you will love all of her documentation.

How To Make Machine Work¶

Info from there:

G-code¶ Now, in order for the C&C machine to understand our commands, we need to generate a G code. This page is a simple tool for g code generation for svg or other formats which we need.

how to use it. step by step guide:

How to add your SVG file.

Now You can change the paramiterrs as you like in this windowes.

Depending on the selected option, the next window will present the setup for the specific task. We can customize it based on our design and tools.

Some important parameters here:

Tool Diameter: This refers to the diameter of the milling or drilling tool used to create traces, holes, or cutouts on the PCB.

Cut Depth: The cut depth specifies how deep the milling tool should penetrate the PCB material when cutting traces or creating cutouts. It is usually defined in terms of a specific depth value or as a percentage of the PCB thickness.

Max Depth: The maximum depth parameter sets the maximum depth that the milling tool can reach during the cutting operation.

Offset Number: In PCB milling, an offset refers to creating multiple passes around a trace or cutout with progressively increasing or decreasing distances from the original path. The offset number determines the number of offset passes to be performed.

Offset Stepover: The offset stepover parameter determines the distance between adjacent offset passes when using offset milling. It specifies how much the tool should move between each pass.

After customizing all the parameters, just save the G-code.

After that, we must download our G-code into a program that can convert it to an X3G file, because our printer accepts only this format. For this, ReplicatorG 0040 can help us. It creates many different files, but for now we need only the X3G one.

How to download ReplicatorG?

You can use this link and download the version you need. Right now, I need the 0040 version. Svetlana gave me this link because ReplicatorG has many versions that didn’t work correctly for me, so I changed it.

What does this program look like? ⬇

what we can do in this program?

open the g code and we can see all strocs and about which it is. JUst open them or put the file on it.

What tools we have and that they mean?

Learn G-Code for 3D Printing: How to Make Your Own Code — Step-by-Step Tutorial

First code i write by myself with Maxime Richard. he study me how the easest codes are working and ask me make write the code which will drow the squear.

the easest code which give me Maxim ⬇

First Gcode Steps¶

;G90

G1 X10 Y10 F500
G1 X10 Y30

The meaning of any sentence

;G90
This is a comment. The printer ignores it. G90 means absolute positioning, but here it’s commented out.

G1 X10 Y10 F500
Move the head to X=10, Y=10. F500 = 500 mm/min (~8.3 mm/s). Move to the first point.

G1 X10 Y30
Move straight up from Y=10 → Y=30. Same speed as before (no new F set).

And after this, Maxim asked me to write the G-code that would make the printer draw a square. At first it was hard to understand how to build it, but after a few minutes I wrote it — and it was actually easier than I expected. You just move one axis at a time, keeping the movements equal for both X and Y, and the printer follows those strokes to create the square.

The Code ⬇

What changes we can have without ;** simbol befor G90** ?

If we will not put this sibol the machin will read this all seperetly. its mean that it will not drow in this example squear. it will drow lines which go up, every axie will read seperatly . it will be easier to show in this picture ⬇

Here I don’t have the nozzle (the head) warming process, but it is enough for first checking if anything works or not. It doesn’t really work yet — the machine didn’t do anything, and the work is continuing.

How to add the warming process: With this question, I went to Google and found the code that makes it work.

The heating code ⬇

M104 S170

M104 is the code, and the number after S is your temperature. I need S170 because I’m heating my vinyls to make them stick together. I tried putting it at the start of the code, and at the end I added a line with S0 to make sure the nozzle cools down after work.

When I started, the printer moved during heating and didn’t wait. Because of that, I added this line of code — M109 S170 — after the heating line. Here, M109 is the code, and S170 is the temperature that the printer will wait to reach before starting the process.

You can use any other temperature depending on your needs. For example, S150 will start heating to 150°C and continue heating during the work.

And what code we have now ⬇

What we have ⬇

The nozle part ⬇

What problems do we have here? I guess you already noticed that the board is not high enough, and that the movements don’t depend on our sketch — the head and the transportation part are all moving on the same height.

Now let’s speak about this printer’s 0-point finding. In old printers it’s a bit hard, and you must do it by your own hand, using the three leveling screws. The biggest minus of this printer is that it is too hard to find the same level across the whole board. All the pins are close to the center, and the corner parts become almost uncontrollable.

Let’s see how it was.

We put a piece of paper under the nozzle and started to level the board up and down, checking how it touches the paper. In the ideal variation, the head should scratch the paper but not tear it. You must do the same for all three points, then check every point again — and also the middle part.

Surely, it is too hard to find anything that will stay in the same position. The printer is old, the leveling screws are not precise, and getting all points equal is almost impossible.

Now about the second problem — the height difference between the sketching (drawing) part and the transportation part. How to solve this?

For this we need another code — G0. G0 is a movement command for transportation, not cutting. With G0 the machine moves fast, without drawing, and we can change its height by editing the Z axis value.

The idea is simple:

When the machine is drawing → Z must be low (for example Z-1).
When the machine is moving between lines → Z must be higher (for example Z5), so it doesn’t scratch the board.

So we lift the Z axis only during transportation moves. This makes the machine safe, fast, and clean — no random scratches and no broken nozzles.

In the ideal version, all transportation moves are written with G0, because it is the fastest way to move around the board.

I added G28, which is the auto-homing command, and G21, which sets the distance units to millimeters. And at the end I put M84, which means the motors will release after the work is finished.

Now let’s look at the kind of code we already have.

G21          ; units in millimeters
M104 S170    ; heat the extruder without waiting
M109 S170    ; heat the extruder and wait
G28          ; auto-homing
G90          ; absolute coordinates

Z0 is not tuchibg the vinyle. we break our heads to understand why. and the resion is to eszy one. the printer 0 paramiters colculating as a printer had with anyn pla as a print. printer head in the printing musnt tuch the the board but becouse we use it for other needs we started to write with pinus simble befor number. For example -4 .

In the middle of our work, everything stopped because of some problems, and I started thinking that I couldn’t do anything that would actually work. But in that moment, my boyfriend Harut came to help — and together we made the first working example.

And we were trying, trying, and trying again. And finally, we had something we could actually call a result. Of course, not everything was perfect — we still couldn’t find a way to change the position, so the changes would work.

The second problem was the height: the nozzle didn’t touch the vinyl and couldn’t stick them together.
