Thanks, yes I was thinking about it :) Maybe in Doter 2.0!

Thanks! Awesome, don't forget to post some images of it :)

I used 9V power supply for powering servos and 12V for LED

AWESOME! It is so nice to see someone make my project :) and it is working very good! It takes some time because those motors are slow, to make it better experiment with amount of steps for each turn on X and Y axis, you have different wheel sizes and thats why those values have to be different. I didn't implement all of the functions in the processing code yet, so as for now it can only print, you can't load a paper and stop. The only way too stop is close the program. Thank you very much, if you need any more help, feel free to ask! I am so happy that someone made my project!

yes, that's true if your Arduino uses different serial port you have to change that, also you will got an error when your Arduino is not connected to the computer

There is place for endstop on the PCB but I don't use it so there is no code for it, but you can easily support it.

Arduino is connected to the computer via standard USB cable

Thank you so much! You project looks awesome, like a baby of Dotter :D it is very well designed also, I really like paper holder. Just change the pins in the Arduino code to yours. You can use exactly the same software, just images that you prepare to draw must be smaller or you can make more dots on each line by reducing number of motor steps between each dot. You can also use my PCB design (so that you will have the same connection) or even buy PCB from me. You don't have to modify processing code, it should work without any problems

Thank you!!!!

Thank you very much! Dzięki :)

For this use those super cheap motors are great. Bigger motors like NEMA 17 would allow me to print faster but that's not really important for me, I mainly wanted to find use for the motors I had and keep it cheap so that others can easily replicate this.

Thank you very much! That's awesome does it also make dots? Or draws lines as a standard plotter?

Perhaps one of the best comments I ever read :) Thank you very much!

Thank you!

Thank you :)

Thank you!

Thank you so much! Greetings from Poland :) I will, always!

Thank you!

Theoretically yes but you should use much stronger construction, stronger motors and something soft under the paper to let the tool emboss the dots

Thank you, I always prefer doing more :) Yes you are right about transistors, that was just to short the things I hope everyone understand what I mean :D Thank you!

Thanks! Sure it can work as a normal plotter, all we need is some Gcode and simple Gcode interpreter for Arduino :)

I just kind not sure what I should reply, seriously. That's the nicest comment I ever read :) I am so happy that someone appreciate my work and enjoy reading and watching story of it! Thank you very much for kind words, I promise to keep up with my projects and make even more awesome things in the near future! Have a great day!

Of course, I want to study at polytechnic, my dream is MIT but it is impossible to do :( Thanks! I hope one day I will be able to design serious products and have my own company!

Thank you very much! :)

no, I don't. Maybe in the second version I will use it, but because of the speed of mpu, there wouldn't be a huge difference in stability

thanks man! awesome to hear that :) I actually really wanted to win a MacBook with this project to improve it and calibrate PID algorithms. Fortunately I won a MacBook with my voice controlled lamp so I will improve this project, and maybe create a Ludwik drone V2. Thanks for your comment ;)

Thank you!

Code is the same no matter if you use Arduino board or my won controller. Make sure that you download a .zip file, copying just .ino file wouldn't work because you need additional files and libraries that are included in .zip

it is the same

Thanks!

app is not my, I just download it from Google play

Yes it is :)

Thanks a lot! for me Fusion is the best CAD I had ever used. I don't really use Linux and blender for 3d printing is not so handy. I used to use it to make models for games but never for 3D printing. I think that fusion is the best because I cannot easily make anything I want and I can do it fast, I can also easily export everything to all possible formats and even do some CAM with it, but that's just my personal opinion :)

thanks!

thanks! :)

thanks :D

Sure no problem, I am here to help :)

Ok :)

Thanks!

Thank you! Yes it is :D of course relay is overkill in this project but I wanted to keep things simple, to make it more begginer friendly, so I decided to use relay. You can use transistor for that I just don't wanted to put there breadboard and relay is simpler to connect. Thanks for comment!

Thanks! Your project is awesome :)

Thanks! What do you mean by scalable?

There are all of the stl files. And about this problem, model was ok, but this part was broken in one place and becuase of that I needed glue.

Thanks!

Thanks! I was thinking about adding it to lazy life, it suits it perfectly :) But you can enter max 3 contests and I decided it will be better to choose those.

Thanks! :)

Thank you so much! That means a lot!
