Hallo, Richtig gute arbeit!
Ich habe ein problem bei compilation, commands-CNC.c: In function ‘PrintMenue_01’:
commands-CNC.c:255:53: warning: ‘%s’ directive writing up to 999 bytes into a region of size 271 [-Wformat-overflow=]
Kann man da was machen?
Me: Entweder ignorieren (die Datei wurde troz der Warnmeldung kompilliert) oder die in dieser Zeile angegebene Variable mit einem höheren Wert für den Speicherplatz (die Zahl in den eckigen Klammern[]) versehen.
Das Programm ist eines meiner Frühwerke und Quick & Dirty geschrieben...

I collect all the part nedded i wanna to cut foam with it
I have 2 motor from old printer "i know you say its has to have at least 60nm but i will use belt instead of scews and for cutting foam i think no much torque will needing "
Can i use one motor for x axis
And i dont wanna the z axis
Any changes in the code if its work without z and the second x?
Me: The only person that can figure out, if your motors can drive your mechanics is: You! Put your machine together and see if the motors have enough torque to drive your setup.
Also: If you try something new, you must live with failures and work around them. That's real tinkering.
You can either modify my Arduino code to totally ignore the second X motor or sinply connect the sensors of X motor 1 to the gpio sensor inputs of motor 2 on the Arduino as well.
With not sending any commands for the Z axis, only X and Y will move. That should work.

You are right but unfortunately its Chinese driver its has no name
1- may you explain to me whats you mean of two input terminals
2-the bts7960 can control 1 motor is that mean i need 3 of them
Me: So you think I am the one that knows all the data of the unknown cheap Chinese boards with no documentation? No!
The terminals needed to control an H bridge. These are usually two per H bridge. The L293 has 4 of them as it is a double H bridge.
The BTS7960 is also a double H bridge, so you need only two of them for 3 motors. You can replace the L293 with the BTS7960 without modifications.
Before you start asking lots of questions on the software side: You had a look at Version 2.1 of this CNC which makes use of bipolar stepper motors and so works with grbl running on your Arduino?

Thanks for the previous answer... I have a few questions, please
1. Is the code modification only if using bts7960?
2. I have an arduino leonardo, will it work instead of an uno?
3. I bought an H DC MOTOR DUAL DRIVE MODULE 20A to run a faster motor. Do I need to modify the code if I use it?
Me: The bts7960 works with two input terminals, same as the L298, so no changes to the software needed if you want to use mine as it is.
The Leonardo will work, too.
Is this a guessing game? how should I know which 20A motor driver you bought?!?

Great machine you made... Thanks
Can I use bts7960 driver instead of l298n to run biger motor with higher current? ... If bts7960 work do i need 4 of them?
Me: You can use any H bridge that works with two inputs, which includes the BTS7960. But keep in mind, that my software is very experimental and this setup won't work with common CNC software (at least not without modifications).

Thanks for the previous questions...
Is there way to speed up the process more than 3mm/s
Is it about the motor or optical sensors?
Me: You need faster motors or rods with a higher pitch (non metric rods), but keep in mind that the torque must still be high enough to move the axes.

Thanks sir its great project to do
.. Is old mouse optical sensor work?...
Is there any possibility to convert this into 3d printer?
Me: Those sensors of old, ball based computer mice might work in principle, but will deliver a high number of pulses per revolution. Your microcontroller must be able to process them all. The threaded rod drive is way too slow to be used as 3D printer.

Thanks for this great work and explaining... Can i use ir sensor i found in hp printer instead of photo sensor cuz i i can't found any
Me: The paper sensors (those detecting if paper is in) of printers are nothing else but IR sensors. You can use them in the same way as the sensors I am using here.
The sensor wheels of printers (those detecting paper movement) can be used in general, but these give too many pulses per revolution. The Arduino won't be able to read these incomming pulses in an adequate pace.
Details in my chapters on using those printer sensors.

Good morning, please, it works for win ?, I suppose it is Ardion code, it can not work with coordinate interpreters under windows, I would add code on Arduino DUE board more memory capacity! then more capacity to process bigger files and convert in 3D printer
Me: The commandline tool I have written, was indeed developed with and for Linux. I don't recommend using the Bloatware and Spyware named "Windows".
...and using a bigger processor and more RAM to achieve a goal is the way of dinosaur Windows thinking. Another reason to leave that behind and enter the Linux and Open Source world, which is for good reasons at the heart of networking and robotics. Time to enter new territories ;-)

Schaut ja ziemlich archaisch aus :D Aber gut erklärt und es funktioniert. Die Präzision würde doch steigen, wenn man dickere Gewindestangen nehmen würde, oder liege ich daneben?
Me: Ist eines meiner Frühwerke. Das von dir als archaisch bezeichnete Aussehen hat schon den ein oder anderen zum Nachbau bewegt, der sich ansonsten nicht an sowas heran getraut hätte ;-)
Die Gewindestangen aus dem Baumarkt sind niemals kerzengerade, daher müssen diese eine gewisse Flexibilität aufweisen, da die Mechanik ansonsten klemmt. Die 6mm sind ein guter Kompromiss. Eine insgesamt bessere Lösung mit Plastikstreifen als Führungsmutter habe ich ab CNC Version 3.2 verwendet.

technical question a favor, I want 3d printer, but with cnc you propose CNC project v2.0 http://www.homofaciens.de/technics-machines-cnc-v2_en.htm
How can I make 3d machine with this same project?
I have arduino mega 2560 please help me interested based on CNC v2.0
please
Me: This CNC is way too slow to become a 3D printer. Another thing is that you would have to do your own coding to make it run as a filament printer. I will build an own 3D printer from scratch when I have finished my CNC v3.2 project that is currently under development. Stay tuned!

Sorry for unclear question.
I have meant that there are may be different step of screw-thread that lead to different length of lines on X-axis and Y-axis.
Thank You.
Me: That's the setting in line 61 of the commands-CNC.c
double StepsPermm = 1000.0 / 31.25;
Mine moves 31.25mm when making 1000.0 steps. It's for X and Y axis, Z axis is the next line. Currently I haven't implemented different values for the X/Y axes. Simply use same threads and sensor discs for both axes (that works even with different types of motors on X and Y).

Hallo Norbert,
Ich bin sehr Interessiert dein mega Spanendes Projekt nachzubauen.
Hätte aber nur einige fragen :
Könntest du mir bitte einen Link geben wo ich genau deine H-Brücken,
Getriebe Motoren , und Gabellichtschranken bestellen kann?
Alles Andere habe ich schon gekauft.
dann eine weitere Frage :
Kann ich auch eine AutoCad ( DWG-Datei ) mit dieser Maschine fräsen lassen ?
Mit freundlichen Grüssen

thanx for reply,
let's assume that i have drawn the *svg file and connected everything properly. now i want to send this file to arduino.
i assume that the program you have written converts the (svg image file) to commands (line, arc.. etc ) as G code (or not)
I am using Windows OS and i don't know how to run *.c in command line as the instructions you have says "open terminal in ubuntu"
if there is any way to run this program from window, can you give details or video on how to operate it
Danke
Me: Sorry, but I don't code for closed source Spyware. The program I have written runs in a Linux Terminal. You can get Linux for free (e.g. Ubuntu, make a backup of your data before installing a new OS).
Yes, once you have followed the installation instructions in the readme, you can select a *.svg file and it is transferred into special commands and sent to the Arduino. G-code is currently not supported, but I am working on a new software that will accept G-Code.
Bitte gerne.

Hello,
thank you for this wonderful project,
I am new to programming and I am good with mechanics, can you tell me how to send commands to arduino? and how to control the steps and speed of motors?
"The software used to control the machine is written in C and it is running from the command line. With the menu you can choose the test pattern and set some variables."
thank you
Me: I can't teach you programing in a comment. The program I have written for this CNC reads coordinates from a file (*.svg) and sends the necessary step commands to the Arduino. Read the source code that is available as download to get the details.

Living upcountry in Thailand I have one problem Are there any 10 mm threated rods online available from about 1300 ?
I have no technical background so the standard places I not know and sitting in a wheelchair shopping is not easy.
Sorry to bother you again
Regards
Meindert
Me: Threaded rods are available in 1000mm length here in Germany. I don't know where to get longer ones. I recommend using 6mm diameter for my design. The overall backlash with a 10mm rod is usually worser.
Another hint:
Small is beautiful (especially if this is your first build)! The accuracy and stiffnes of a CNC is worser the larger the construction. It's also no fast machine, thus driving in a 1300x1300mm area will take a very long time...

Haben Sie schon gesehen das dieser Beitrag auch auf Wikipedia, im Englischem Beitrag zur Arduino Plattform unter dem Punkt "applications" vorletzte Zeile , verlinkt wurde? Das ist doch großartig oder?
Me: Ich fühle mich geschmeichelt - danke für den Hinweis.

mr norbert, i have verify and compile the arduino.ino file in Arduino.IDE, but it cant upload.it says dev/ttyACM0 permission denied.
In the terminal, the message i get "Last error: init_serialport: Couldn't set term attributes
Waiting for 'X' from Arduino (Arduino pluged in?)..."
Me: You can't expect the terminal program to connect to the Arduino if you have not done the upload of the Arduino sketch. Does the command:
ls /dev
list a device named ttyACM0? I am waiting for your screenshots.

my linux version: ubuntu 16.04LTS
Arduino.IDE version: Arduino 1.6.6
Me: You still did not answer what you have done to make the "permission denied" message appear in a terminal. Send me screenshots of the steps you have done.

mr.norbert, my Arduino.ide and the terminal shows that dev/ttyACM0: permission denied (after adding my account to "dialout")
What i have to do? Is it means my arduino UNO board did not connect well?
Me: You still did not tell me what Linux and Arduino IDE version you are using. What have you done that the "permission denied" appeared in a terminal?
Try starting the Arduino IDE with root permission in a terminal:
sudo arduino
