The ini file is pointing to an io.hal file that does not exist in that folder.
You can try omitting that entry in the ini file, but might be needed for the config to work, so better try to find the file if you are sure it is needed.

twopass:CANNOT FIND FILE FOR:io.hal

seems that you are telling it to load 'io.hal' somewhere but don't have that file in your config.

So i was able to get PB to launch and then i tried to do the modifications that were recomended on the start screen. I modified my HAL and INI files and now have the following error report..

Glad you got it working.

Внес исправления как написал, скомпилировал, запустил = РАБОТАЕТ! Ай да Пушкин, ай да сукин сын!
Made corrections as written, compiled, launched = WORKS! Oh yes Pushkin,

hatte meine 7i92 auch letzte woche bekommen,
hab nicht viel getestet, aber läuft soweit.

probably, this is influenced only by that part of ini where the formula XXYYZ and then something like that? -


// Apply inverse matrix transform to the 3 cartesian coordinates
pos->tran.x = invdet * ( (e * i - f * h) * j[0]
+(c * h - b * i) * j[2]
+(b * f - c * e) * j[4]);

pos->tran.y = invdet * ( (f * g - d * i) * j[0]
+(a * i - c * g) * j[2]
+(c * d - a * f) * j[4]);

pos->tran.z = invdet * ( (d * h - e * g) * j[0]
+(b * g - a * h) * j[2]
+(a * e - b * d) * j[4]);

    // Pass rest of axes as identity
    //if (EMCMOT_MAX_JOINTS > 3) pos->a = j[3];
    //if (EMCMOT_MAX_JOINTS > 4) pos->b = j[4];
    if (EMCMOT_MAX_JOINTS > 5) pos->c = j[5];
    if (EMCMOT_MAX_JOINTS > 6) pos->u = j[6];
    if (EMCMOT_MAX_JOINTS > 7) pos->v = j[7];
    if (EMCMOT_MAX_JOINTS > 8) pos->w = j[8];

// Apply matrix transform to the 3 cartesian coordinates
j[0] = pos->tran.x * a + pos->tran.y * b + pos->tran.z * c;
j[1] = pos->tran.x * a + pos->tran.y * b + pos->tran.z * c;
j[2] = pos->tran.x * d + pos->tran.y * e + pos->tran.z * f;
j[3] = pos->tran.x * d + pos->tran.y * e + pos->tran.z * f;
j[4] = pos->tran.x * g + pos->tran.y * h + pos->tran.z * i;


    // Pass rest of axes as identity
   // if (EMCMOT_MAX_JOINTS > 3) j[3] = pos->a;
    //if (EMCMOT_MAX_JOINTS > 4) j[4] = pos->b;
    if (EMCMOT_MAX_JOINTS > 5) j[5] = pos->c;
    if (EMCMOT_MAX_JOINTS > 6) j[6] = pos->u;
    if (EMCMOT_MAX_JOINTS > 7) j[7] = pos->v;
    if (EMCMOT_MAX_JOINTS > 8) j[8] = pos->w;

?

This is certainly not a one-size-fits-all solution with automatic situation recognition, but for a specific situation

So I installed python3-pyqt5.qtquick and now it works !!!! Thank you sooo much!!

hal+ini

Habe meine Mesakarten vorgestern erhalten, gestern getestet. Sowohl die 7i92, als auch die 7i98 funktionieren einwandfrei mit originaler Mesa Firmware. Auch die Busschalter funktionieren so, wie sie sollen (inkl. Pegelwandlerfunktion). Die Widerstände an den Pins sind externe pull-up Widerstände.
 

Bei der 7i92 ist es wichtig, die richtige ZIP-Datei herunterzuladen (für die 7i92H oder 7i92TH). 7i92t.zip lässt sich nicht flashen.
Wichtig zu wissen ist, dass der Fallback-Jumper nicht funktioniert.

Falls die Karte vom Raspberry nicht erkannt wird, muss man zuerst die Verbindung über die Konsole herstellen:

sudo ip addr add 10.10.10.11/8 dev eth0
sudo ip link set eth0 up

Ich bin mit dem Kauf jedenfalls so zufrieden, dass ich eine weitere 7i98 bestellt habe, diesmal in 7i92-Größe: de.aliexpress.com/item/1005010164826951.html

Sorry, I'm a total beginner when it comes to this stuff. I'm at the copy and paste stage and don't really know what I'm looking for on that link...Is there a specific package I should download?

Sorry I may have given the wrong package.
Have a look at this one.
packages.debian.org/trixie/amd64/python3-pyqt5.qtquick

Many apologies I was working from memory and apparently my memory was corrupted. I apologise for any time wasted.

Regarding the python errors if yo get a ModuleNotFoundError you can search for the name of the module that is stated as missing .

When the tech bros talk about realtime they aren't referring to the PREEMPT RT kernel that Linuxcnc requires. That requires setting a couple of extra options in the kernel config. I understand that it can appear confusing.
Whilst I haven't built a 3b distro, I only have access to a 4 and 5 there just might be a chance that the experimental image I've been working may work. When I say work I mean it may boot, as for latency, you may need to add isolcpus 2,3 to command line text. Even then I can't guarantee that latency will be suitable.
The thread I started regarding the experimental image has a link to the image.
