Hallo zusammen,
es gibt ja die Möglichkeit, Inhalte eines Parameters während dem das NC-Programm ausgeführt wird, in eine Textdatei schreiben zu lassen.
Zum Beispiel hier:
.......
N10 (LOGOPEN, ausgabeX.txt)          (Neue Logdatei erstellen oder bei vorhandener Datei die Inhalte löschen)
N20 (LOGAPPEND, ausgabeX.txt)     (Messwerte zu Logdatei hinzufügen)
N30 (LOG, <#5061> X-Achse)            (Werkzeugradius, aus dem Parameter #5061 in Logdatei schreiben)
N40 (LOGCLOSE)                               (Logdatei schließen)
.......
Meine Frage ist, ob es möglich ist den Wert des Pins "hm2_5i25.0.encoder.01.count" während der Programmausführung, also ähnlich wie oben in eine Textdatei schreiben zu lassen?
Oder alternativ den Wert des Pins "hm2_5i25.0.encoder.01.count" in einen freien Parameter ablegen zu können?

Gruß Peter

If you are not using reset mode (Not sure if the RPI can do this)
The step pulse width is the base period.

Drifting in a (mod) 45 degree angle suggests crosstalk to me.
Maybe a loose ground or 5V common in the step wiring?
 

That's it! Somehow the stranded wire connecting d- and p - to GND broke in the ferrule. After I replaced the wire, the drifting is gone!

Thanks! 

Hi Arciera,

use libgsl example. Remove all libdogleg related files and deps.

Hello everyone! I'm using the analog signal to determine a limit switch. Through a reading from a magnetic sensor that has an analog voltage output that is read by the 7i77 board, I developed a logic in the LinuxCNC classicladder. The logic is that when the voltage is greater than 7.5 volts then it activates the output %Q81 called MA-Z, when the voltage is less than 1.0 volts then it activates the output %Q80 called MI-Z and the home position is when the voltage is 6 volts it activates %Q82 called HO-Z.



I made a virtual connection in the HAL file

Includes the configuration to activate Home by switvch in the INI file

The machine makes the movements when pressing the + and - buttons of the home z, but when trying to do home axi with exio Z, a movement calculation error appears. As per the video below


 

Please, does anyone have any suggestions, I'm trying to find a way to make this Z axis movement stay in an initial position above the top, to avoid the movement collision of the tools. But I can't get the system and 7i77 board to interpret the virtual limit switch, could it be that I'm missing some configuration in the HAl or INI file so that the home axi Z works correctly?

 
 

Yes, 7I76E hal and ini files will work with a 7I76EU.

The added 7I76EU features (output modes and spindle mode)
would not be supported, but these are just controlled by parameters
that  can be setp'ed in the hal file.

The firmware files are however different

Moved to another PC, installed 'libdogleg-dev' and I seem to get a little further but not much:

 

Anyway, I'm afraid there is not much I can think of to help as I'm really starting a zero with these dogleg solvers.

Blender CAM 2025
Please give some inputs, is it worth the effort to learn?

Hi,

I have tried another solver: "libgsl".     ( sudo apt-get install libgsl-dev )   Using the GPU. ..

This runs way better then libdogleg. Was a luckie shot.

In this solver bigger distances are ok.
Input :


interpolated endpoint result : x: 520.049999 y: 266.500001 z: 125.500000
Converged after 370 iterations wtf? 

Now i get more convinced finally.

Appreciate the prompt action, I also got a reply from the Mesa folks that you can select and build configs with 7i76E as well.
