Can you give me a list of materials need ASAP? It would be a huge help


Me: All the materials needed are listed on the page, aren't they? If you miss something, you must tell me EXACTLY what, that would be a huge help to me ;-)
AND: ASAP is a phrase you can use when talking to people you pay for doing a job. I hardly recommend avoiding it when talking to people that give you something for free that you are obviously not willing/able to do!

Hi Norbert
I'm still here.
I would like to adapt your project to this: (https://www.thingiverse.com/thing:2401997) because I know better the raspberry than arduino.
Do you think it's possible? obviously using a different power supply

Me: Bipolar stepper motors are usually driven by constant current and not by constant voltage as the special motors I am using in my CDROM Plotter. The accordant driver chips use step and direction commands, so you must at least transform the functions of the stepping commands in my software and of course use different motor drivers (e.g. A4988 chips).

Norbert, I made changes to the values and was able to affect the servo but not to what I needed. I used a different servo from an old RC airplane model, and it is now working perfectly. Thanks again for your help!

Me: Good to know you managed it. Probably the first servo needs 5V pulse level and doesn't work fine with the 3.3V from the Raspberry Pi.

Norbert, I have one last question. It seems the servo, when going down, will swing approximately 190 degrees. Then when it comes up, it only comes up about 180 degrees. I cannot find in the .c file what determines the travel of the servo? I need to make it travel the same amount in both directions, ideally 90 degrees. Can you help with this? Best regards, Andrew

Me: It's in line 28 and 29:
#define SERVOUP           10
#define SERVODOWN         20

10 means a 1.0 ms high signal which is usually 45 degrees, 20 means 2.0ms which is -45 degrees. Play with the values to see if you can make it fit to your requirements.

Norbert, I used the c program for the plotter, printer, miller on https://www.homofaciens.de/download_en.htm#PlotterCDROM. The one from the zip file works perfectly. The crashes are due to me trying to use incompatible file formats. Your instructions for Libreoffice work perfectly. I now have the machine working well, thanks for your support, it has been fun to learn. You are very clever for having developed this!

Me: Thanks for pointing out what went wrong. Thant might help people that stumble over the same error.
There is nothing better than exploring successfully what makes a machine work or not work - congratulation on making your's do what it should do.

Norbert,
Thank you for asking about file versions, that must be the problem.
I am running Raspbian 9, and I was using cdrom-plotter.c version .1. I found version .5 in the zip files with the images. I tried using .5 but it seems the mapping of the GPIO's is different.
In version .1, it was setup as GPIO [6] = 13. In .5, I see "#define X_stepper03 2" for example. Does this mean that stepper03 is mapped to wiringpi 2, which is P1-13?

Thank you for your continued help!
Mit freundlichen Grüßen

Me: In what zip-file did you find a .5 version of plotter-cdrom.c? Not in the plotter-cdrom.zip of the download page.
The mapping of the GPIOs should not matter with the wiringPi library I am using, so use the pin header numbers of the circuit drawing (P1-..), no matter what Pi revision you have.
Did you reinstall Raspbian on the SD card to get a fresh installation? That might cause your crashes.

Thank you Norbert for all your help! I have successfully been able to move the X and Y axis and pen servo using the menu options in the program. The last problem I am having is uploading a file. When I select the file (files I got from PLOTTER-CDROM.ZIP), the program crashes, and the terminal window closes. All .svg and the .bmp files cause the program to crash. Any final advice you can offer would be appreciated.

I've learned so much so far, thank you!

Mit freundlichen Grüßen

Norbert, I am starting to wire up my Pi, and I am having some difficulty understanding what is meant by your GPIO connections to the bridges. In your graphic you say "Bridge X Input A GPIO 2 = P1-13". What is meant by the "P1-13"? I understand Bridge X Input A goes to GPIO pin 2, correct? (I have a raspberry Pi 2 B+), It looks like yours is a Pi 1? According to this https://goo.gl/TDe1Jm , GPIO 2 on Pi 1 is Pin 3.
Mit freundlichen Grüßen

Me: It's the pin header Number. Number P1-1 is the +3.3V Pin, P1-2 the +5V pin and so on. Take this scheme for the wiring, since there are different GPIO numberings for the Raspberry, which might confuse you. The numbering is identical for all Raspberry models, no need for changes.
See all pin numbers at my chapter about the Raspberry Hardware pins

Thanks for your direct answer!

Do you have any documentation for your C code in order to help me or any other to understand the functionality?
Does it implements g-code moves or uses the svg and bmp images from scratch and interpret them to head moves?

Sorry for all these questions, but I really interesting for modifying your project for educational use.

Thanks again!!

Me: The gcode version of my software is still under development. I will publish the source when my CNC v3.2.2 runs fine with it. The software only implements Gcode commands (moves and spindle/coolant). I won't update the CDRom plotter (at least not in the near future). This machine is for playing only, it's not meant to be a tool as my CNC routers are.

Nice project!!!
I was wandering if I can use Python with RPi.GPIO library instead of C and wiringpi.h library...

Thanks :-)

Me: Thanks!
If you know how to do coding, you can of course translate the C program into Python code or do it from scratch by writing a totally new code. My program for this plotter is open source, so it's up to you.

Norbert, I have begun collecting parts to try building one of these so I can learn microelectronics. Thanks for the excellent idea and tutorial. Can you recommend a source for the L298N bridges in USA? Also, are those capacitors connected to the L4940V5? I am referring to: https://www.homofaciens.de/bilder/technik/plotter-cdrom_010.htm

Thanks in advance!

Me: L298N bridges are commonly available. Just Google for it and pick the online shop you trust.
As you can see on the drawing you refer to, the capacitors are connected to the pins of the L4940V5 which is a 5V linear voltage regulator. The capacitors smothen the input and output voltage. The regulator is not needed if you use a 5V DC power supply instead of the 6V lead acid battery I was using.

Hi!, I followed all the steps, but when compiling the program I skipped the following error "usr / bin / ld: can not find -l / usr / local / include collect 2: error: ld returned 1 exit status" . I do not know if it will be but when I do the ./build of the wiringPi at the end  I skip a note saying that to complete programs with wiringPi, you need add: -lwiringPi. If you could help me. Thank you very much, bye

Me: That build instruction for wiringpi installation is no longer needed. It is now part of the offigial packages, so all you need to install is:
sudo apt-get update
sudo apt-get install wiringpi
I have changed that in the readme.txt

why do you have 5 volts going from the pi to the servo? seems redundant. Please forgive my ignorance.

i reconnected the x axis and some how it worked. i checked the p1-7 on the RPI so I'm sure that there is no wiring issues. (connected multimeter to Rpi  pin without any wire) the problem is p1-7 is not actuating at all. whats going on?
thanks for your time

Me: And it's really pin 1-7 you checked? I sometimes mess up the numbers...
Try the following:
In the source code "plotter-cdrom.c" change Line 41 from
#define Y_STEPPER03 7
to
#define Y_STEPPER03 0
and recompile the code. Now, chek if pin P1-11 has 3.3V when pin 1-7 should have 3.3V. If that is true, change the wire from the L298N from P1-7 to P1-11 and see what happens.

Hello again,
found the problem for x axis and now it working but the y axis the p1-7 is not giving any output to l298N. As you said for every step one of four gpios must have 3.3v and the others nothing. i tried each step for it and getting the proper output until p1-7 must get an output of 3.3 v's. doesn't have any outputs at all!

Me: Would be nice if you tell me what the issue with the X axis was. Other readers could learn from your error detection, too.
Did you try to read the voltage output with a multimeter at the GPIO of the Raspberry AND at the cable end going into the L298N? It could be an issue with your cabling.

Hello norbert,
I have a problem,my x step motor goes to one way properly, the other way is 3 an then back to were it was (press cursor 4 times to right, 3 right and 1 to left(the length is 3). The y motor is just vibrating cursor in any way makes it one up and one down.:( what the problem? I have checked my wiring but there is no problem?
thanks

Me: Did you use the Pin header numbers P1-xx for wiring? There are two different GPIO numberings and when following the wrong one your plotter won't work, thus the pin header numbers are best.

Hello,
don't no if you had the answer or not, i have the answer for vibrating motors on Rpi 3. the problem is they use gpio numbers to connect the boards to Rpi! i've tried it out and get the same result, but after using the pin number they  worked fine! use p1-13 instead of using gpio2!(if you see the new Rpi pinout you will find that some of the GPIO pins on older models had been replaced by non-GPIO pins(like p1-4 is 5v). Hope thats helpful.Thanks for your amazing tutorial!

Me: Thanks for pointing that out. I have added a remark on my pages and the schematics to make that clear.

Hallo, ich mache ein Uni-Projekt und möchte dein CD-Plotter nachbauen. Dazu verwende ich diese H-Brücke https://www.sunfounder.com/motor-drive-l298n.htm. Ich habe alle Komponenten so wie es bei dir im Schaltplan steht miteinander verbunden und an RasPi 3 angeschlossen. Leider funktioniert nur das Servor-Motor und Schrittmotoren nicht. Ich habe die Verbindungen 100mal am CD-ROM getauscht habe, funktioniert leider nicht. Ich bin ratlos. Gelten die GPIO-Positionen auch für RasPi 3, H-Brücke falsch?

Me: Der Link funktioniert nicht. Es wäre auch besser, wenn du nicht auf einen Online-Shop, sondern auf ein oder mehrere Fotos deiner Platine und deines Plotters verlinken würdest (oder noch besser per eMail zusenden). Dann kann ich sehen, was du eventuell falsch machst.

Hallo ich mal wieder, irgendwie komme ich nicht weiter bei meinem nachbau ich habe das jetzt exakt so nachgebaut wie beschrieben, allerdings verwende ich den Raspberry Pi 2 B+ und anscheinend sind bei dem die gpio Ports anders definiert. Ein Motor zuckelt nur vor sich hin wenn ein .svg file plotte es hört sich auch so an als würde er unterschiedliche wege fahren der zweite Motor macht weit weniger Geräusche. hier ein Bild von gpio readall https://www.dropbox.com/s/he5xjfc1um6vjg3/Screenshot%202017-02-03%2020.46.00.png?dl=0

Me: Die GPIOs liegen bei allen Raspberry Modellen an den GLEICHEN Pins. Du darft da nichts ändern. Orientiere dich also an den Pin-Header Nummern in meinem Schaltplan (P1-..), dann sollte es klappen.

Hi,

Ich suche mir gerade einen passenden Schrittmotor für das Projekt. Ich weiß leider nicht, auf was ich achten muss beim Kauf (würde mir das Auseinanderbauen des CD-ROMS gerne sparen, weil die Motoren offenbar recht günstig sind).

Was ist z.B. davon zu halten?

https://www.amazon.de/gp/product/B00PZY9EBW

Falls der nichts ist: Könnte ich eine Empfehlung für einen geeigneteren bekommen?

Danke & Grüße!

Me: Diese Schrittmotoren sollten funktionieren. Der Vorteil an den CD-Laufwerken ist halt, dass da gleich die Führungen für die Achsen mit dabei sind. So musst du was eigenes konstruieren.
Viel Spaß beim Basteln und gib "Bescheid" wenn dein Plotter läuft. Würde mich interessieren, wie deine Lösung aussieht.

Hallo,

ich habe die Hardware soweit auf gebaut.
Ich habe das Problen das x und y Achse nicht gleich sind.
Wenn ich ein Quadrat von 30mm x 30mm plotten möchte passiert folgendes.

Die x Achse wird mit 15 mm und die y Achse mit 30 mm geplottet.

Wo liegt der Fehler ???

Danke für jede Antwort.

Gruß gero (Anfänger)

Me: Dann hat dein Y-Motor eine geringere Auflösung als dein X-Motor. Die Software geht davon aus, dass beide Achsen Motoren mit gleicher Auflösung (Schritte pro mm Bewegung) verwenden. Im Quellcode (plotter-cdrom.c) kannst du die Zeilen:
double StepsPermmX = 250.0 / 35.0;
double StepsPermmY = 250.0 / 35.0;
anpassen. Versuch mal die Werte:
double StepsPermmX = 125.0 / 35.0;
double StepsPermmY = 250.0 / 35.0;
Dann neu compillieren wie in der readme.txt angegeben und testen.

I'm sorry, I know you told me multiple times, but because there were a mistakes in your schematic this make me in trouble,in your schematic the physical pins of X are P1-15, P1-17, P1-23 and P1-25 and not P1-13, P1-15, P1-21 and P1-23.
Sorry again

Me: What schematic are you talking about? On my page there are the pins 13, 15, 21, 23:

Me: I told you multiple times to use the physical pin numbers in my schematic! The X motor uses pin P1-13, P1-15, P1-21 and P1-23 and you are using P1-3, P1-5, P1-8 and P1-33. Find the correct pin numbers for Y motor on my schematic.

Thank you for your time.
what is the type of numbering should be in the C program?
if the answer the GPIO numbering, why my plotter not operate?, I wire the RPi pins as stated in its manual.
Could you help!!!

Me: Send me a photo of you wiring so that I can see if it is okay or not. As stated before, use the pin header numberings listed in the schematics! P1-13, P1-15 and so on!

Thank you for your time.
You used GPIO 13 for InC of bridge X which equal to physical pin No. 33 while your RPi has only 26 pins max.. how?
Are the pin numbers of the C program the GPIO numbers?, what is the physical number of GPIO 0?

Me: No! there are (at least) two different GPIO numberings. That of wiringPi I am using obviously differs from yours. That's why I recommend use the pin numbers in the schematics.
