Now that the RPI5 has a driver suitable for the 7c81, it’s time to see if this BSPI thing works on the clone I put together.
I’ll use your thread as a reference, print out some of the man pages, 7i65 code, some data sheets and get the highlighters out. I guess a I’ll have to build the bit file as well.
 

IIRC the problem with BSPI is that it was rarely ever used after it was written. I guess one lesser known Mesa card used it and I could only dig up a single ancient thread about it. I recall I was asking about it and toward the end of the thread it clicked in my head how the data packets work......then I shelved it. Maybe I'll get back to it one day.

Hi everyone,I’m currently working on calibrating my 5-axis CNC milling machine, and I’ve encountered a few challenges. I need to accurately probe multiple points on a workpiece (such as a rectangular block or sphere) to align the machine and compensate for any errors. The goal is to determine the exact machine positions relative to the theoretical workpiece coordinates.For this, I’ve been debating whether to buy a commercial probing tool (e.g., Renishaw or Blum) or design and build my own probing tool. Here’s what I’ve been considering:
 

• When the B-axis is tilted, compensating for the probe radius can get tricky. For example, if I’m probing a side of a rectangular block, I have to account for offsets in both X and Z (or other axes, depending on the tilt). This makes me wonder if switching to a spherical calibration disk might simplify things, as the sphere has constant radius compensation regardless of tilt.
• I’ve designed a potential DIY probe where the tool tip is connected to 24V, and the workpiece (or calibration disk) is connected to the CNC controller’s input port. When contact is made, the circuit closes, and the signal is detected. This seems similar to how commercial probes work but is much simpler.

my Questions are : 
1- if i switched to spherical shape instead of rectangular one will it simplify the calibration process, especially when compensating for B-axis tilt?
2- is there is a predefined probe radius compensation in linuxcnc which i can use and it take considaration a titled workpiece
3- For a DIY probe using the method described above (24V signal on contact), will this provide sufficient accuracy and reliability for calibration purposes or should I invest in a commercial probe for the long term ?

I have the deb downloaded, but i cant get it to run

Egal welches der beiden Relais inaktiv geschaltet wird, es dauert knapp 2 Sekunden bis die Maus wieder läuft.
Innerhalb der 2 Sekunden ist die Spindel schon zum Stillstand gekommen.

Maus ist kabelgebunden

Habe ich das richtig gelesen wenn alle Relais aus sind und die Spindel läuft leer aus dann hast du noch die Störung der Maus ?
Wenn ja ist das ein Ooooh….
Hast du eine Kabel Maus oder eine Funk Maus ?
Es könnte auch die Maus sein…

Right now I'm just looking at how Arduino-connector handles connection states. It seems that even the normal outputs don't reset when LinuxCNC is closed so things that were previously on (like LEDs) stay on. The same happens with the I2C outputs so I suppose it's expected.  Not sure if that's the intended behavior but I've trying to figure out how to reset all outputs (pull low) on disconnect. It's a bit hard to debug since there's only 1 serial connection referenced and it's taken over when LinuxCNC connects, but I have another serial port I can direct debug prints to.

Yes, I figure it is dangerous if the Arduino changes States by itself, at least if People decide to connect other things than LED Lights in Buttons to the Output pins. I implemented new settings in the new version that allows to define behaviour if the connection is lost.

Other than that it all seems to work pretty good, I found a blocking delay in the comalive function that was creating a bit of delay. I replaced that with a timer and it works much better. That plus the tweaks mentioned in the git issues, it's pretty responsive now.

Once I get done putzing around, I'll clean up my code a bit and upload it somewhere.

You can create a pull request if you want and I will merge it into the project.
 

Ich denke die Spindel. Denn wenn ich über den Maschinenzeitigen (zweiten) Start Stop Schalter die Spindel ausschalte, dann geht die Mouse. Das Relais ist dabei aber noch geschaltet, weil der Kontakt über die Mesa ja noch aktiv ist.

Man merkt auch, dass der Auslauf der Spindel weiterhin die Mouse beeinträchtigt, obwohl das Relais bspw bereits inaktiv ist. Also tippe ich stark auf die Drehbewegung der Spindel

It is crazy having such an out of date package still being the default.

Try using the buildbot at <buildbot2.highlab.com> 

Es ist die Frage erzeug das Relais das die Spindel einschaltet ( Hauptrelais ) die Störung oder ist es der Spindelmotor
Oder ist es das 12 V Relais.
Da muss man sich Stück für Stück durch hangeln.
Ich hatte auch letztens ein Problem mit ein Monitorkabel an mein Plasmatisch in der Testphase war alles gut jetzt musste das Kabel länger sein ein neues gekauft bein zünden des Brenners Monitor Schwarz zurück getauscht alles gut andres Kabel diesmal vom Hersteller des  zu kurzen Kabel gekauft alles gut.
Das mit den N kommt nur in einigen Teillen von Europa vor wo die L Position an der Steckdose nicht definiert ist zb ein. US Stecker geht nur in der eine Richtung das ist auch einer der Punkte warum in Caravan Sektor der Cee Stecker Blau 240 Vorgeschrieben ist der L und N ist definiert das mal
zur Info.

Thanks Phil,

I'm using the latest version from Synaptic Package Manager

I have tried to get 2.9.2 & 2.9.3 to load from usb, but i'm not having any luck with this.

About to enter the build bot rabbit hole.

Cheers

Has anyone been able to get the position of the servo motor via modbus and then do the homing operation?

But I get the error

What error?
