Oh sorry. I am really sorry. I will make CNC-V-2. I am asking the same question. How should I change the elektronics if I choose 1 motor for X axis? I have 3 motors which are all 4 amperes. Will it work if I simply short the digital pins 10 - 12 and 11 - 13? or should I buy one more and make the exact same copy?
Yusuf

Me: You must change the software code on the Arduino to make it work with only one X motor or you could try to switch the light sensors of one motor in parallel. To do so, link the input pins A2 with A4 and A3 with A5 on the Arduino. Never shorten output pins!!!. However, I haven't tried that and changing the code on the Arduino would be the better solution.

Another question is I have to drill 672 holes to put leds into. How can I make the svg file? Will it work if I only put some dots and convert to svg as you do? Any advice?
Thanks in advanve

btw I am buying components. I hope I will start to make cnc machine next weekend.

Me: Drawing circles and export to svg will work - that's how I am doing it.

Hello again
How should I change the elektronics if I choose 1 motor for X axis? I have 3 motors which are all 4 amperes. Will it work if I simply short the digital pins 10 - 12 and 11 - 13? or should I buy one more and make the exact same copy? all motors are 1300 rpm (I will make simple gears to reduce it around 130 rpm) also I have to make h bridges (IRF540 IRF9540 pair with optoisolators)

Why do you need 2 TCST2103 for each axis? You can easily calculate the position by one of this device. You are using a counter for each position of these devices. For example
LH to HH you add 1 to counter
LH to LL you subtract 1 from counter.
Why do you need that. You can use one TCST2103 and you can check to polarity of the motor. For example
L to H +1 if polarity is CW
L to H -1 if polarity is CCW.
Or vice versa. By doing this you can have more accurate steppes.

You need some space for 2 device configuration. By 1 device configuration you can make these gaps much smaller and you can count it anyway. By 2 device configuration each 3 degrees counted for counter. By 1 device config you can count every 1/2 degrees maybe less than that. By this way steppes can be smaller and positioning would be more accurate. You should only follow the rotation of the motor for adding or subtracting for counter. Is there any problem with that?

2nd z axis can behave as driller. 1st can behave as engraver. 2 different images can be uploaded to machine. Distance between 2 axis can be calculated. While 2nd z axis run this much distance can be added or substracted to original home position. Or 2 different home position can be pointed to machine. First thing first. I have to build that cnc than try the 2nd axis.
Yusuf

Me: Yes, make an exact copy before starting to implement your own stuff.

Thanks for publishing my previous posts. Raspberry pi will be a good and easy solution for the machine. is there any room for 2nd z axis on top of the y axis? I need to carve and cut some woods with it. both job needs different procedure for it and different feed rates. with the same mechanism both z axis can be driven. by this way job can be done without changing the setup.
Yusuf

Me: Well, can you do the coding for that special add-on? I won't do that for you, bacause I am too short in time.

Hello
You can easily convert these cnc machines to Laser cutter engraver machines. Maybe you will try that soon. Also you can convert these to 3D printers. These are really good projects. I am watching your videos over and over.
Yusuf

Me: The CNCs I have created are too slow to convert them into 3D printers. I will instead ceate a filament printer from scratch. Lasers are dangerous - don't play with those devices if you don't know EXACTLY what you are doing!

Thanks for these great projects.

I want to try that v2.0 machine but I want it as a standalone machine like headless cnc. Is there any chance that you have tried a 2nd arduino with sd card reader added and attached to your primary arduino? I do not want to put a computer next to cnc and wait till ends the job. I need to mill a pcb and cut some 6 or 8 mm thick woods. (fixed milling shape but high quantity)
Why do you choose *.svg files insted of g-codes?
Thanks in advance
Yusuf

Me: You can use a Raspberry Pi instead of a laptop. I have currently no plans to make it a standalone machine with a card reader.
I choose *.svg because it was easy for me to create and export those files with LibreOffice draw. I am working on implementing G-code.

Hi Norbert!
Thanks for all good examples.

I could have sworn on that I have seen a video where you explained the basic behaviour of a PID regulator..
You used the wiper motor and implemented P, I and D one by one and ended up with a "tight" regulator.
Did I dream about this? I'm not able to find that video:-(
Please let me know where to find it.

Thanks

Hallo,
und erst einmal Danke für die wahnsinnig vielen und sehr guten Erklärungen, Videos und Infos! Die Videos bringen den Sachverhalt auf den Punkt ohne viel Geschwafel und Füllwörter. Ich nehme an, dass hier sehr viel Textvorbereitungen) von statten gehen.
Ich habe spontan über Deinen Link einen 3d Drucker bestellt.
Ich bitte um eine kurze Info, mit welchem Programm ich am Besten die Konstruktionen vornehmen sollte?
Was nimmst Du? Sorry, falls es irgendwo steht. :-)

Danke im voraus,
Galm

Me: Danke für die Komplimente und ja, für meine Videos schreibe ich zuerst immer ein Skript.
Zur Software für 3D Drucker habe ich bislang noch nichts geschrieben, das kommt noch...
Ich verwende openSCAD zur 3D Modellierung und Slic3r zum Festlegen der vielen Druckparameter sowie zum Erstellen der G-Code Dateien.
Was für einen selbst das Beste Programm ist, liegt im eigenen Ermessen. In openSCAD werden die Modelle mittels Mathematik dargestellt (parametrisierte Darstellung). Das ist sehr nahe am Programmieren und liegt mir irgendwie im Blut. Modelle mit der Maus zusammenklicken ist nicht mein Ding...
Slic3r bietet wirklich viele Einstellmöglichkeiten und durch die kämpfe ich mich zur Zeit, um das Optimum aus meinem neuen 3D Drucker herauszuholen.

hi!
i am using your code for cnc v0.6. I have constructed the hardware but i do not know how to cut anything with it. i can not understand the read me file and i dont even have a Linux machine. Is there anyway i can cut something through windows 10?
thanks for your assistance,
Mihir.

Me: I don't support closed source Windows spyware. You can get Linux (e.g. Ubuntu on www.ubuntu.com) for free and install it on your PC (don't forget do make a backup of your data before installing an OS).
Obviously you can read English, thus you should understand the readme in principle. You must tell me EXACTLY what step you don't understand if you expect to get help.

Hi Norbert!
Just come here to tell you how much addict i have been to your videos and tutorials. I have been in electronics all my life (i am 57 y.o.) but i found up  Arduino (Uno),and i have been improving my skills in computer language (was about zero)  related to this tiny microcontroller.
Having 1 ton of old and recent canibalized photocopy machines/printers in my backyard,i was in need of learning from someone who can merge both sides of this hobbie.
Thanks for sharing!

Me: You are never too old to learn new tricks and printers and photocopy machines are great sources for sensors and motors. I will build more machines using those scrap parts.

Hi, since i saw this site, i was hope i can develop something that i have been looking for for a long time,
I'm from Tanzania/Africa here stepper drivers like easy driver for CNC machine or 3D printer are not yet available, and even to order them it takes time, which i don't have. But i have access to arduino, the only choice i having is code the arduino to act as stepper driver which can accept steps, Direction and Enable pin. i dont care if i can use the whole arduino for a single stepper moto

Me: Besides Arduinos you'll need H bridges and DC motors as well as optical sensors form old printers to get stepper motors that can be controlled by Step/Direction pins. That's what I will do with my latest CNC v3.x that is under construction. For the CNC at least 2 Arduinos will be needed to run the machine with grbl to process G-code.

Hätten Sie einen Tipp für mich bzg. des Aufbaus und Sketch ?

Viele Grüße

Hi there, I really like your work. The practical uses of these boards is really quite impressive. I'm kind of a virgin on the coding side but the mechanical & electrical side I will have no problems. So maybe a suggestion on the first time setup of coding would be a great help in a video on that CNC machine. The how to's and different variations & complexities.

Kind regards, Graeme.

Me: There is a quick instruction on how to set up the software in the download packages.
I will create some more chapters about "Physical Computing", showing how to use an Arduino or Raspberry Pi to move the world. When? Well, hopefully in the not so far future...

I hope to, thanks
