It looks like there is one target (with a magnet?)
Is the problem that the sensor is also detecting the bolt heads?

Can you describe the system in more detail, including what position feedback there is and how the system is driven?

Hi Bernhard,
verstehst du richtig so, RPI + Parallel Hat is das selbe wie PC mit Parport,
die step-signale werden im Raspberry erzeugt und an den GPIO pins ausgegeben.

Nachteil: Jitter und nicht allzu hohe beschleunigungen/geschwindigkeiten möglich.
Vorteil: günstiger

bei Mesa werden die schnellen stepper-impulse im FPGA erzeugt und der Raspbi gibt nur die befehle an die Mesa per Ethernet oder SPI und erhält den aktuellen status zurück

Gruß,
Olli

EDIT: für so ne diadrive reicht der RPI mit Hat völlig aus, die geben 'max. 20 mm/Sek.' an, dafür brauch man keinen FPGA
 

Okay I remember there was a section in the CNC panel for tools and hal stuff so I poked around there and found the specific call-out I need to address the 7i84. I'm starting to get excited as I was able to make something actually happen finally. I controlled an output on the 84 for "coolant" now I just need to add all of the lines for my machine and wire everything. I will likely return with more issues but I will probably make a new topic mostly for tracking my progress.

I have a new section in the error codes where it does say it can see the 7i84. So it must be my call-out for the pins are incorrect. I am referencing a project where the guy had his 84 wired to his 7i77 but I am using the 7i74 to communicate with the 7i84 and 7i73. Is the pin call-out different currently it is "HM2_5i25.0.7i84.0.2.output-10"

I decided I didn't like the looks of the Ethernet cable I was using so I went and grabbed 2 different ones to try. When I plugged it in a new yellow light turned on and when I launched the CNC page it blinked green a few times before giving me the same error pins on 7i84 don't exist.

I saw the question and you have now attached exactly the relevant files. Thanks, I'll be happy to think about it!

OK. Best of luck Rod.

No I didn't get a blinking green light, the 7i77 flickered a few times and went back to red.

Hello,
iḿ a newbie (from Germany) and i just build a new mill. Now I want to configure my Mesa 7i76e. However, I can't get TB5 and TB6 to activate. Just TB2/TB3, P1 and P2 are visible.
Please help

Danke, das ist schon mal ein Ansatz! 

Im Moment sehe ich da zwei Möglichkeiten:
- Raspberry Pi 5 + ein Parallel Hat von byte2bot
byte2bot.com/products/parallel-port-rasp...gak8F2DJq1o7WoFK2x-g

Verstehe ich das richtig, dass damit die Erzeugung der Signale die an meine Fräse gesendet werden im Raspberry stattfindet, und somit von der Systemauslastung, Latenz, etc.. abhängt?

- Raspberry Pi 5 + MESA 7C81
Während hier die Signale in/von der Mesa Karte erzeugt werden?

In beiden Fällen muss ich die .hal Dateien so anpassen dass die korrekten Pins angesprochen werden, das ist mir klar.

Aber funktioniert das grundsätzlich so, oder liege ich daneben?

I assume the ERC60 just reports back the commanded position as actual position, without knowing if it lost steps.
Have you verified with halshow that  joint.2.motor-pos-fb =cia402.2.pos-cmd and cia402.2.drv-actual-position = lcec.0.5.actual-position?

That looks like the situation I had yesterday. Traced it to a bad kernel (I think I traced it there).
I upgraded the kernel to latest 6.12-48 and all problems went away.

I got lot's of errors yesterday and going in and out of PREOP. 
It might have been a bad kernel. I upgrade to latest 6.12-48 and the problems went away.
Think the bad one was 6.12-38.

Got that too yesterday. Traced it to a bad kernel think it was 6.14-38 or so. Upgrade the kernel is my advice.
 

Well, I just found another mistake.
My spindle driver only has two pins: forward and reverse; it doesn't have an enable pin.
And I had wired spindle.0.on to the driver's forward pin instead of spindle.0.forward.
The good news is that the PID speed still works fine.
The bad news is that the orientation doesn't move at all anymore, nothing...
