Thanks cakeslob, I copied everything from yours last time, the only thing I don't have is the low pass, I'll give it a shot thanks

chargepump macht 500Hz, benötige aber 10kHz

Category: Deutsch

If you need a 10 KHz chargepump (and you can spare a step/dir output)
I would use the last stepgen as a chargepump

You do this by setting stepgen 4 to velocity mode and quadrature:

setp hm2_7i96s.0.stepgen.04.control-type  1         # velocity mode
setp hm2_7i96s.0.stepgen.04.step_type  2             # quadrature so square waves
setp hm2_7i96s.0.stepgen.04.stepspace 5000       # short enough to not interfere
setp hm2_7i96s.0.stepgen.04.steplen      5000       # ""
setp hm2_7i96s.0.stepgen.04.maxaccel 0              # make velocity command instant
setp hm2_7i96s.0.stepgen.04.velocity-cmd 10000 # 10 KHz
net machine-is-on hm2_7i96s.0.stepgen.04.enable

And then use stepgen4's step pin as a 5V 10 KHz chargepump signal

QtPlasmaC v2.9 - Time between turning off and back on the arc on a Powermax 105

Category: Plasma & Laser

I think you have a wiring fault. All the 105 does is close an internal relay when a valid arc is established. you provide the voltage to that relay and read the output when it opens and closes.I would confirm behaviour with a multii meter before going further.

We can't help until you provide full details of your THC, the way you have integrated with linuxcnc and the connections you have made.

Most people  use a Mesa Ethernet card and Mesa THCAD and not use an external THC.

Please don't duplicate your replies.

chargepump macht 500Hz, benötige aber 10kHz

Category: Deutsch

Hallo, ich bin gerade dabei meine Ansteuerung für die Fräse von Mach 3 auf LinuxCNC umzubauen. Die Fräse ist eine High-Z S-1000/T mit einer Heiz Zero-3. Diese Steuerung benötigt ein chargepump Signal. Aus meiner Mach3 Steuerung kommt dafür eine Frequenz mit 10KHz, womit es funktioniert. Aus meiner Mesakarte 7i96S kommen leider nur 500 Hz. 
In dem Konfigurationstool von LinuxCNC kann ja auf einen der Output's ein chargepump-Funktion gelegt werden, diese habe ich ausgewählt. Wie kann ich die Frequenz bestimmen die da heraus kommt?
Was ich auch vergeblich gesucht habe, gibt es jemand der eine fertige hal bzw ini hat die mit einer 7i96S und Heiz Zero-3 Steuerung zusammen arbeitet? Dann könnte ich diese als Grundlage nehmen oder im Vergleich mit meiner evtl. feststellen was ich falsch mache.

Gruß

Hey Murphy, i cant really see whats happening in the video but i think I can tell

github.com/cakeslob/RRW_LAB/blob/inc/Lin...c/remora_encoder.hal
github.com/cakeslob/RRW_LAB/blob/inc/Lin...c/remora_spindle.hal
check out these 2 hal files, specifically the encoder one, or just try them out. the encoder one has a lowpass filter to smooth out the rpm signal

QtPlasmaC v2.9 - Time between turning off and back on the arc on a Powermax 105

Category: Plasma & Laser

Hi snow. Thank you.
I am using mode 2.
I have also a external THC as an independet electronics.
I am using ArcOK signal from the CNC port on the plasma cutter. The problem that I am finding out is that the Hypertherm PowerMax 105 is sending an ArcOk signal as soon as I send the signal to turn the arc on to the Powermax.
I will study the differences between mode 1 and 2 and will review if the PowerMax is set to work and such a way or if this is a problem on the Powermax.
As the Power Max always sends the Arc Ok signal, when the arc is not transfered to the part, QtPlasma does not try to start the arc again and the part program runs without cutting the part.
I will also try the recommended solution from the QtPlasma manual that tell us to make 3 turns with the power cable that goes to the plasma and use a reed switch inside those turns (as item 6 of the Plasma Cutting Primer for LinuxCNC Users Document).
Once again, thank you very much.

Thank you very much for your reply
I acted in this way
By running the following program, two txt files will be created, one to save the new numbers created in a specified format and the other to save all the numbers to avoid repetition.
import random
import os

existing_filename = 'random_numbers.txt'
new_numbers_filename = 'new_random_numbers.txt'

if os.path.exists(existing_filename):
    with open(existing_filename, 'r') as file:
        existing_numbers = [list(map(int, line.split())) for line in file.readlines()]
else:
    existing_numbers =


def generate_new_numbers():
    numbers = set()
    while len(numbers) < 12:
        number = random.randint(0, 20)
        numbers.add(number)
    return list(numbers)


while True:
    new_numbers = generate_new_numbers()
    
   
    if len(new_numbers) == len(set(new_numbers)):
     
        for existing_row in existing_numbers:
            if new_numbers == existing_row:
              
                break
        else:
 
            break

with open(new_numbers_filename, 'w') as file:
    for index, number in enumerate(new_numbers):
        file.write(f'#{200 + index}={number}\n')


existing_numbers.append(new_numbers)


with open(existing_filename, 'w') as file:
    for line in existing_numbers:
        file.write(' '.join(map(str, line)) + '\n')


Then I defined an M code to run the program
And in the Gcode file, by calling the file that contains variables #200 to #212, I entered the value of these variables into the Gcode program.

Age of the website and forum

Category: Forum Questions

@cornholio: I was more interested in the structures behind it, which I don't know as an outsider.
The Kunena Forum can take over the complete user structure of Joomla with all rights etc., which is quite complex, at least that's how I understood it on the Kunena Forum website.

Of course, you can also create and operate the forum separately from the website (with additional rights management etc.).

The current OS


That's a silly question, sure. Is the server environment created by yourself?
Or is the server environment managed?



Notes:
1) If we have installed our own server that runs on Ubuntu, the server may need to be updated.
1.1) Ask the person who installed the server!
1.2) Do nothing without a backup!!!

-- when the server is cleared and done --
2) Check which PHP version is installed
2.1) Update if necessary
3) Check which database is installed (probably MySQL, which version)
3.1) Update if necessary
4) Check which domains are available and where they are forwarded to.
4.1) List of all domains with internal/external destination folder
4.2) Check all start folders of the domains ‘.htaccess’ whether redirects exist here www without www https forced etc. ...
5) Check the user administration of the forum to see if it is connected to Joomla.
5.1) If no, much easier, if yes, think again!
6) Create new folder for new forum
7) Install new forum incl. new database etc.
8) Possibly check with the forum manufacturer Kunena whether user data, posts and images from the old forum can be exported/imported to the new forum.
etc.

But the beginning is very important, because this is the basis for everything else and when I look at what @JT has provided us with as a layman, I get the impression that it is not a finished server (which a service provider takes care of), but that the server was set up itself, which then also has to be maintained!

There are 3 active forums at the same time,
..
forum.linuxcnc.org
...
www.forum.linuxcnc.org
...
162.243.45.186

I hope not!

My site is accessible with and without www, but there is only one page.
All visitors who come to my site without WWW are redirected to the WWW page on the server side!

Google and Co. don't want duplicates either and usually remove such things from the INDEX! which would be a great pity!

I have the impression that I have not yet fully understood how the whole thing is structured and that we are talking past each other in the wrong places.

Ich schätze mal, das liegt oft auch am Problem der Begrifflichkeiten und auch sicher an meinem Englisch, was von DeepL kommt ;-)

rotation plane around y axis in g18

Category: G&M Codes

The usual approach is to create a configuration for vertical and another for horizontal operation but
one can easily create a kinematic that allows for switching between vertical and horizontal spindle orientation even in Gcode.
