Diving deeper into linuxcnc

Category: General LinuxCNC Questions

Go to the 2.94 docs and click down the HAL (Hardware Abstraction Layer) section to see how hal works
Then click on the button that says expand man pages
Take your time reading the man pages to learn what hal can do out of the box.
You only need to learn a bit of Python if you want to write or modify a GUI. Google has a very good Python course
Personally, Before tackling Python, I would learn how to write real time components using (a variant of) C and look at some examples in the linuxcnc source.
github.com/LinuxCNC/linuxcnc/tree/master/src/hal/components
copy a simple one like and2 and rewrite it into a different one like and3

"pwm/dir" (Out1) switches for spindle CCW

Category: Basic Configuration

Hi there
A question about my configuration:
1. I have a HF milling spindle which needs only to turns clockwise. The PWM canal (Out0) works fine. My config for "pwm/dir" (Out1) is set to a relay output (P17/"GPIO7"). The relay should be on when CW is commanded but here it is on when CCW is commanded. How config it so that the relay switch on when CW is commanded?

Here two pictures of the PCB board, which receives all the signals from the Heidenhain TNC113.

Clearly a prototype and it would be extremely difficult to perform a re-engineering and create the circuit diagram.

best practice Benutzervariablen anzeigen und speichern

Category: Deutsch

Hallo zusammen, 

Ich bin neu im Forum und möchte mich bei Allen bedanken die dieses tolle Projekt vorantreiben und verbessern. 
Habe LCNC 2.9.4. auf meinem NUC seit einigen Wochen am laufen und schon viel im Forum gelesen. 
Nun bin ich aber auf ein Problem gestoßen wozu ich bisher noch nirgends eine Antwort finden konnte. 

Ich benutze in meinem Programm einig Anwenderparameter (#31 usw.) welche ich während dem Programmlauf beobachten möchte!. 

- In der linuxcnc.var geht es live und zur Laufzeit nicht . 
- in der  LinuxCNC-Status-Anzeige (linuxcnctop) auch nicht. 
- in der  HAL Konfiguration unter "watch" ???  --> macht es Sinn, -  Alle meine Parameter in der INI unter einer Custom Section anzulegen und so     zu  beobachten?   
        --> Wenn ja wie werden die dann persistent gespeichert?
       -Hätte diese Vorgehensweise Vorteile, wenn ich später noch eine GladeVCP Oberfläche dafür bauen möchte?
- Ansonsten gibt es noch die Befehle MSG , DEBUG, usw... ->  Jedoch habe ich beim CNC-Programm-Ablauf kein Meldungsfenster mehr, - anstelle dem ist ja der NC Code zu sehen und die 1000 aufpoppende Fester rechts unten sind dafür wenig praktikabel. 

Nun mein Frage:
Wie kann ich am besten meine Variablen während dem Programmlauf live beobachten? 

Viele liebe Grüße
Korre

Hi Mark,

here I'm adding some pictures. The spindles accept 8 mm Watchmaker collets from Boley & Leinen and G.Boley, Unfortunately Schaublin B8 does not fit because of the too narrow slot on the shaft of the collets. 

       

Best regards

Retrofitting a 3-axis VMC with DC servos - guidance needed

Category: Driver Boards

Hi, thanks for sharing your Maho retrofit experience, very interesting project.

my machine uses DC servos with ±10 V analog control.
I’m currently deciding which Mesa hardware to choose, but I’ve noticed that most of the combinations I had in mind are out of stock.

One of my doubts is regarding communication:

Some people suggest parallel-port-based cards for heavy, real-time work.

Others mention Ethernet-based cards might be better for future expansion.

My concern is whether Ethernet introduces more delay or has less data transfer capability for this kind of servo control — or if I’m completely wrong in that assumption.

Could you share your opinion or recommendations on:

Which Mesa cards you would choose for ±10 V DC servos in a retrofit like mine.

Whether you think Ethernet is a good choice for long-term expandability.

Any reliable sources or distributors where I might be able to get the boards (especially in Latin America, but I’m open to others).

Thanks in advance for any insight!

Okay, I understand what you're saying. One option I'd considered is to connect the driver's OnPos signal to an input on the MESA card to cushion these offsets due to speed and acceleration, so the program doesn't continue reading until they're reached. I don't know if that makes sense or if it's just a wishful thinking.

Also looking into TAILS a linux distro. It also uses TOR.  I am not surprised about VPN's it seemed
like a convenient way to funnel people into specific systems. Kind of like saving everything into
cloud servers except all in real time.

I have two ebay bought used  EXE's on my mill. 602D/5-F  and 602/1-F.  I never did figure out Heidenhains model numbering, so I ended up with one providing 1µm resolution, and the other only 5µm.
How I wired them up is here:
www.forum.linuxcnc.org/12-milling/33035-...0e?start=1340#152364

Those Leinen FM 1 are lovely machines. Please add pictures to your thread. Lots and lots of pictures :)

Heidenhain EXE610 - which MESA board would be needed to connect 4 of them?

Category: Driver Boards

I have LS403's with EXE's feeding into the 7i77 on my mill, and a ROD and modern servo's encoders feeding into a 7i85 on the lathe. As Andy said, any of the mesa cards with encoder inputs will work fine.
