Lieber Nobbi,
du könntest ja auch mal Lego Mindstorms in deine CNC Reihe aufnehmen.
Me: Ich behalte Lego als Baumaterial mal im Hinterkopf. Die Mindstorms Steuerung mit den entsprechenden Motoren ist mir aber zu speziell. Ich baue lieber mit Zeugs, das ich in alten Geräten finde.
Ich könnte meine Meinung aber ändern, wenn Lego sich bei mir meldet und ne Kiste mit Elektronik zusendet ;-)

Mich würde interressieren welche Abmessungen diese Maschine hat. (Arbeitsbereich,...)
Me: Die hatte ich als Demo, ohne Funktion gebaut und mittlerweile wieder zerstückelt. 3mm Hartfaserplatten sind viel zu weich, als dass man mit einer derartigen Maschine was sinvolles anfangen könnte.

Hi again,
In my class of 8 groups we've finished 3 models. 5 more to go, although one group may have given up.
I had an idea to simplify the design. Instead of using epoxy on the threaded rod to make a switch, how about cutting the round servo horn (or inserting a pin) to make a cam? The cam can move one paperclip to touch another one (like the limit switch). It makes the operation more obvious, and requires less work to make.
I may do this if I have time. I could use the abandoned model.
Me: Great to hear that you already turned 37.5% of your students into real engineers. I am sure you won't give up until you got all of them ;-)
Inserting a pin on the servo horn (maybe a screw) is a good idea, that might save build time. Let the world (and me) see it in operation.
Thanks again for sharing your thoughts!

Just a quick update. First, 1.3mm card is no problem. Also, is it worth adding the approximate cut-length of the threaded rod to your instructions? I estimated X=120mm Y=140mm and Z=100mm. A little longer is okay, and the length does not have to be accurate. Do you agree?
My students have done 2 classes so far. Each class is 1h10m. Most groups have finished cutting. Some groups have almost finished gluing. My plan for 6 classes is: Cutting, Gluing, Motors, Switches, Wires, Software.
Me: Thanks for the update and for the remark about the cut length of the threaded rods. I have added that to the description. With the finished machines you can do more than one class programming the software. Since the Raspberry Pi has more computing power than the Arduino I was using, you can even teach algebra with the plotter software.

Eine Frage zur Konstruktion aus Hartfaser-Platten(Video_5:45):
Weißt diese Maschine bessere mechanische Eigenschaften auf als CNC_v0_6?
Me: Die Hartfaserplatten-Maschine am Ende des Videos habe ich nie fertig gestellt. Die sollte nur als Demonstrationsobjekt dienen, ich bin aber gleich zur richtigen CNC v3.2 übergegangen. Besser als CNC v0.6 wäre die nicht geworden. Die 3mm Hartfaserplatten sind viel zu weich.

Thanks for fixing the numbers. Green looks like light grey, so your numbers are now white with a light grey border. They are much more visible when printed. I would recommend in the future maybe green characters with a black border, but it is not necessary to change it now.
I have cut all of my pieces, and I acquired some 1 metre M3 threaded rod in Seoul. Now I will start gluing!
Me: Good news, thanks for the feedback!

In Figure 17 you say "Attention!
X22 and Y22 have to be glued on the back side of this picture when using the CNC with servo drives!"
But, the photo indicates X28 and Y22. Is this an error? Do you mean "When using servos do not use X28. Use X22, and glue it and Y22 on the 'back' side of this picture."?
One more thing, sorry, when I print your photos in black and white the labels are hard to see. Green is printed as pale grey, just like the background. Maybe use a font with an outline?
Me: Yes, it must be X28 and Y22 in the text besides the photo. I have corrected that.
I will see what I can do to give the numbers a better visibility in grayscale prints - it's no quick fix...
Thanks for your feedback!

I have started to build this. By which I mean I have printed the artwork and I am cutting the pieces. I live in Korea, but I can not get 1.5mm card here. However I can get 1.3mm card, so I am using that. I also do not have M3 threaded rod yet.
I am hoping to build this with some my Korean students (I teach English here). I will make one, and show them the video. Then I hope they will be excited to build one too. I have 18 students, so I will make six models with teams of three.
Me: Great to hear about your project. The 1.3mm cardboard should work, too. It's no high precision machine, just a demonstration of how things work in principle.
Hope to see your machines running, soon.

I run in to problems with libraries having differences.
There are some Arduino libraries that will only work for AVR chips.
If you lucky you can find the problem code and work around it.
I surprised that the Arduino based IDE works as well as it dose on the ChipKit and Launchpads.
The board have very different microtrollers, for the most part they can run Arduino C++ code.
Libraries hard to follow to, you get lost in code.
Thanks
Wrt_uas
Me: ...but libraries make programming so much easier. There are years of programming in the Arduino IDE and libraries, that's what many companies offering microcontroller boards simply can't do, thus they simply try to make it Arduino compatible. Since they usually even haven't enough man power to test all Arduino libraries, failures are inevitable. That's why the original Arduino / Genuino boards are the better choice.

Ok
I did look at the servo library code after I commented last.
They wrote the code so there a constant pules with.
I found a min pulse value of 544 us and a max of 2400 us like you mention in your servo video.
The servo.write command only takes integer values degrees between 0 and 180.
The Energia Servo library has a Servo.readMicrosecond command that not in the Arduino Servo library.
Thanks

I built a test platform, it works and I'm work out the control for the servo motor.
Have you ever gone and look at the code into the servo.h library.
As I understand it analog servo operation between 50Hz and 60Hz.
The code for example sweep program
myservo.write(pos): // pos is 0 to 180
delay(15): //fulls out the rest of the pulse
If they putting a pin high and low again, there a change that pluses are not there same length.
thanks
Wrt_usa
Me: Creating pulses having EXACTLY the same length is not necessary. Just keep the error below a given pulse width. A hobby servo with a potentiometer as sensor won't be able to follow a variation less than an arcminute, thus an error of one arcminute won't really trouble your servo control.

TI Launchpads have a different jumper set up than the Arduinos.
The pin names are the same for the special function pins.
There a sub-directory there has all the micrcontroller parts defined,
anything that connected to micrcontroller also has a definition.
ChipKit dose the same thing.
As long as you don't need to do anything that requires direct hardware access you can write code for all 3 platforms.
TI want to use the TI launchpads because they have a low power micrcontroller.
Thanks
Wrt_usa
Me: That sounds interesting, but I have no time nor money to try another board for my physical computing chapters, thus I will stay at the Arduino platform for my machines.

I modified a servo for continuous rotation.
It works but it hard to stop it moving.
I'm using a Texas Instruments (TI for short) Launchpad MSP-EXP432P401R to drive the servo
Launchpads are TI answer to the Arduino, they around half the price of the Arduinos.
TI was smart and made a Arduino base IDE called Energia.
As far as I can tell Energia functions the same as Arduino IDE

Me: The question is, if the code is compatible and you will have to figure out, what pin belongs to the same functionality at the Arduino. If it doesn't work, I won't be able to assist you with your problems, since I don't own a TI board. If you are an expert in microcontrollers you will be able to save some dollars, if not, you will buy lots of problems...

Hallo
Ich wollte nur fragen ob die CNC V3.0 mit einem Arduino oder per Raspberry PI angesteuert wird.
Was wird genau als Antriebsspindel der XYZ Achsen benutzt. Gewindestangen mit M6,M8 oder M10 Gewinde oder wird etwas Anderes mal ausprobiert.
Zum Späteren Design wäre ein Mix aus Rot,Grau und Blau gut. Dann hat es einen Metall Look.
UNBEKANNT
Me: Es wird eine CNC v3.0 bis 3.9 (oder so) geben, d.h. verschiedene CNC Maschinen mit einem Grunddesign, aber aus verschiedenen Materialien (Holz, Kunststoff, Metall). Ebenso wird es verschiedene Antriebe geben mit unterschiedlichen Motoren, Gewindestangen und in den Topmodell(en) Trapezspindeln.
Wenn ich von Design schreibe, dann meine ich mehr so die Hardware-Konstruktion an sich, nicht die Farbe ;-)

Ich habe bisher Ausschlachtmotore aus alten Plottern,Druckern sowie Kopierern der 80er90er genutzt
Daten der aktuell genutzten sind 0.9Nm nema23
Die in neueren Geräten zu finden ist schwer.
Empfehle daher eher Das closed loopsystem mit stärkeren pollin DC-Motoren und sich die H-brücken mit z.B MJE3055
und MJE2955 (bis zu 150W) zu löten.
Aber werd erstmal abwarten,was der Erfinder sich so ausdenkt
Me: Ja, zumindest in den niedrig- bis mittelpreisigen Druckern neuer Bauart sind "nur" Gleichstrommotoren mit Photosensoren zu finden, aber die sind ja nicht uninteressant.
Mal sehen, wieviel Ampere die so ziehen und dann über entsprechende H-Brücken sinnieren. H-Brücken selber Löten ist aufwendig wenn man Sicherungen gegen zu hohen Strom, Kurzschluss und Shoot Through einbauen möchte und ohne Sicherungen birgt die Verwendung einige Gefahren in sich...
Mal sehen, was so geht. Im Augenblick bin ich dabei eine Modell-Mechanik aus Hartfaserplatten zusammenzukleben. Danach geht's an die Elektronik.
Der "Erfinder" hat noch längst nicht alles gedacht was zu denken ist, daher werden Anregungen weiterhin gerne entgegengenommen ;-)

Zitat:
4. Die Maschine soll die Teile zur Anfertigung einer Kopie seiner selbst fräsen können (Selbst replizierend)
Zitat ende:
Dazu sollte der Vorschub der Achsen um den Faktor 5-10 erhöht werden.
(Vermutlich ist dies der Grund,weshalb die Maschine aus 6mm Sperrholz entstehen soll.)
Hab jetzt alle Varianten einmal durch.Am besten geht die 2.1 in Pvc bis 25mm sowie Alu -8mm bei Zustellung 2mm bzw 0,6mm (jeweils 150mm/min)
Holz möchte so 1200mm/min,sonst iss'es mehr ein....äh Brandschneiden.
LG
Me: Die Geschwindigkeit zu erhöhen steht recht weit oben auf meiner Liste, aber die Grenze setzen die Motoren. Mal sehen, was ich in meinen alten Druckern so finde. Mit Motoren aus dem Versandhandel geht's auf jeden Fall besser.
8mm Alu? Hätte ich dem Ding gar nicht zugetraut. Man benötigt natürlich einen leistungsstarken Fräser mit wenig "Schlag".
Brandschneiden? Ja, damit habe ich gewisse Erfahrungen gesammelt ;-)
Holz ist natürlich nie gleich Holz...

Mir persönlich,gefällt ja die DC-Motorvariante sehr gut,weil man da mehr Auswahl hat und rel. leicht, höhere Drehzahlen bzw.Drehmoment realisieren kann.
Wie wäre es, das Prinzip der Führung von der v2.xx zu übernehmen?Dazu könnte man an die Auflage,sowie an die Unterseiten der Platten dieses 20x20
(oder kleiner)Winkelprofil schrauben.Weniger Reibung sowie Spielärmer.
Als Lager könnte man die (überall billig im zu bekommenden Inlinedinger 22x8x9mm nehmen
Das wäre so mein Vorschlag
LG
Me: Das "closed loop" Prinzip bei den DC-Motoren sorgt dafür, dass keine Schritte ausgelassen werden können, was enorm wichtig ist. Habe mir schon ein paar kaputte Drucker besorgt, die ich demnächst auseinandernehme.
Die Führung wird derart geändert, dass die Schienen umschlossen werden d.h. Oben und Unten befinden sich Kugellager (der Vorschlag mit den Inliner-Lagern ist gut). Die selbstzentrierende Variante mit den im 45 Grad Winkel verbauten Führungen der 2.x Maschinen wird aber durch plan aufliegende Profilleisten bzw. Platten ersetzt.

Good job and best of luck for the HackaDay Prize!
Maybe this CNC will be possible for me to build - ur other ones are way too good and materials are not available here, but this one's description says it will be made of easy to find materials available in almost all countries at affordable prices.
So danke and best of luck!
Me: It will be more than just one CNC, but all based on (more or less) one design. There will be a high quality machine using ball screws, bipolar steppers and a metal frame that sets the reference. The idea is to get as close as possible with a variety of materials and drives. A local printer repair shop gives me the unrepairable devices, thus I can do some investigations about what parts to salvage from those gold mines.
Hope to see you CNC one day!

HALLO,
Also die Maßen auf dem Plan der CNC V3.0 wirkt 5mm oder 6mm Sperrholz sehr dünn. Erstens 8-12mm Sperrholz saugen Holzlack gut auf und weichen dann nicht gerade so viel auf und 8-12mm sind stabiler. Während bei 5 bis 6 Millimeter Ist das schon recht instabil. Holzlack empfiehlt sich auch gut wenn man mal Plastik schneidet und ein paar Tropfen gegen das Holz spritzen.
Also der Plan ist trotz allem gut.
Sperrholz ist eine Gute und schöne Material Wahl.
Viel Spaß noch beim Bau !
Me: Besten Dank für die Rückmeldung.
Der "Plan" ist momentan noch kein wirklicher Plan, sondern mehr so ein Platzhalter. Bezüglich des Materials werde ich verschiedene Versuche unternehmen. Bei Sperrhols mehr als 10mm ist in jedem Fall zu empfehlen und gegen Wasser zu schützen macht auch Sinn. Ich habe im Keller 3mm Hartfaserplatten rumliegen. Daraus werde ich die Tage erst einmal einen "Dummy" basteln, um ein grobes Design vorstellen zu können. Ab dem Zeitpunkt bin ich für weitere Vorschläge offen.
