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

Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

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.
