Erst einmal vielen Dank für dein Interesse an meinem Problem!!
In welcher Sprache bist du aufgewachsen?

Ist die ISO 6.13 RT released?

Die ISO auf dem link runterladen, neu instalieren, testen.
Diese ISO hab 6.13 RT kernel, soll kein probleme vie die 6.01 im die officielle ISO haben, kan aber andere probleme habben.
Sorry, aber ich schriebe English mehrfah schneller. Und mache wenig fehler... :)

Ich habe keine Ahnung was du mir damit sagen möchtest.
Es hat schon seinen Grund, warum ich im deutschsprachigen Teil dieses Forums schreibe.

Aber gerne berichte ich, ob der Prozessortausch etwas gebracht hat.

Danke für den Link.

Die Installation der "r8168-dkms"-Treiber hat leider den Fehler nicht beseitigt.
Bevor ich tiefer in einem Betriebssystem herumstümper, das ich nicht verstehe, werde ich erst einmal die CPU tauschen.
Ich hoffe mit einem i5 ist das Problem dann beseitigt.

Danke und Grüße,
tinker

Category: Basic Configuration

Hmm...

There must be a solution so your setup can be XYZABC.

How does the PC communicate with the machine?

I use a Mesa 7i76eu with ethernet.  I'm guessing with a little trial and error I could modify the kinematics file to just set the B axis value to a constant 0 to avoid it being in the calculations for TCP and then passthrough the actual value to my joint.  The actual matrix math stuff is well beyond my level, so I'd rather leave that alone.  Not totally sure I'd want to label it B axis instead of W anyway, since B wraps around Y in my head.

I'm going to work a bit on trying to get the axis to retain position values when it's in spindle mode, I'm using a step/dir servo, so I need to figure out a way to keep track of position somehow.

hm2/hm2_7i76e.0: error finishing read! iter=1342204

Category: Deutsch

Hallo zusammen.Nachdem ich ein paar Erfahrungen mit einem ArduinoUno und ESTLCAM gesammelt habe, versuche ich mich jetzt an LinuxCNC und einer MESA 7i76eu. Mit Windows kenne ich mich recht gut aus. Mit Linux leider noch gar nicht, darum bitte ich um Nachsicht!Mein System besteht zur Zeit aus einem i3 mit 4GB RAM und zwei Realtek LAN-Adapter (einer OnBoard, einer als PCIe-Karte); Debian 12 und LinuxCNC 2.9.4.=11.0ptWie bereits an anderer Stelle hier im Forum beschrieben erhalte ich nach einiger Zeit folgende Fehlermeldung: „hm2/hm2_7i76e.0: error finishing read! iter=1342204„

Wie in diesem Thread ( Mesa i76e error finishing read. Another Time with LinuxCNC 2.9.1 ) beschrieben, habe ich ethtool installiert.Das Auslesen der Werte mit „sudo ethtool –c enp1s0“ zeigt, das „rx-usecs“ bereits auf 0 gesetzt ist.
Soweit ich den Thread richtig gelesen habe, sollte diese Einstellung (bis zu eine reboot) die Fehlermeldung unterdrücken/beseitigen.
Auch habe ich in der Maschinen-INI den Parameter „SERVO-PERIOD“ auf 2000000 gesetzt.Vielleicht hat ja jemand eine Idee, woran es liegt, dass dieser Fehler geschmissen wird. =11.0ptDanke im Voraus und Grüße vom tinker.

Stepper motors should hold position when error. was created by LeonDolnicar

Stepper motors should hold position when error.

Category: General LinuxCNC Questions

I am running a 3 axis CNC mill with stepper motors, through a 7i76eu card running linux CNC. Currently when one of the motor drivers gets a fault, the motor lose all power. This is problematic for the Z axis, which uses a stepper motor with a brake. When its driver gets a fault the brake is engaged, but there is a delay, in the meantime the z axis is in free fall for about 10cm. Is it possible to program the stepper drivers in such a way that when they get a fault they stop the motors and hold the position.

Thank you for all the answer and suggestions in advance.

No, I have a 7i76e with lots of inputs. I used to have a machine run off a parallel port, though, which has very few inputs.

I was able to check the connection yesterday, you were right, [GND pulse - dir -] I had them bridged. !!

I always connected them, I understand that it's wrong! I like to learn because the board can get burned with this connection. I thought that the ground from both the driver and the board should be connected.

thank you!!!

I'll try to fix these - however if anybody has a quick idea what needs to be done to fix them your help is always appreciated :-)
Thank you so far for your quick help to get the machine up and running again!

Looks like the latency is worse than Debian 12 (if Debian 12 was working)

What does:

sudo chrt 99 ping -i .001 -c 60000 -q [card_ip_address]

report ?

Where [card_ip_address] is the ip address of the 7I76E

(the command will run for 1 minute and then print statistics)

 I am going to check the connection, I should have connected TB2 pin 2-4 with the white wires [ Pulse - ] [ Dir - ]  from the Driver. 
the pink cable from the X connector seems to enter pin 2, I need to check!!

 thank you very much for the observation !!!!!!!!!!

I'm a bit concerned about the STEP/DIR wiring.

It appears that the thick white wires are grounding the STEP- and DIR- pins
This should never be done as it shorts out the STEP- and DIR- pins
possible damaging the driver chip.

If STEP- / DIR- are unused, they should be left unconnected.
