I think that _some_ Fanuc serial protocols are supported by Hostmot2:
linuxcnc.org/docs/stable/html/man/man9/h...html#Fanuc%20encoder
 

Mark's message gives the details of the serial protocol.  I don't know why he had to duplicate the effort, I have already deciphered these encoders and have a protocol converter product.  But, now, Fanuc has a "High speed" encoder line that is incompatible with the older ones.

Can you check that the drive is in OP like below
 
And with halshow that you have the same values in the following parameters,
not the commanded and actual positions of course, but they should follow the same pattern.
 

For your Z drive.

jenachdem wie dein bob aufgebaut ist, also das hinter dem 25pol stecker,
kann man die auch mit 3.3v betreiben, also direkt am GPIO vom raspberry.
Diese china bob's www.amazon.de/Fasizi-5-Achsen-CNC-Breako...reiber/dp/B09Z29TYNL
hatte ich schonmal direkt am 3.3v FPGA vertratet

Danke, dann versuche ich das mal!

Raspy ist bestellt, mal schauen wo der Parallel Hat aufzutreiben ist.

Ich melde mich wieder, sobald ich alles da habe und in die ersten Fehler laufe..

Die Diadrive ist schon recht langsam (und auch nicht sehr stabil), aber für meine Zwecke voll ausreichend.
Gfk und CFK in 1-4mm geht gut, und ab und zu Holz oder ganz vorsichtig etwas Alu schafft sie.
Da drauf sind schon ein paar Motorradrahmen und viele Teile für meine RC Bikes entstanden. 

@tommylight I'm curious why you are recommending that I push to use the resolvers instead of switching to encoders? Shouldn't I want to use the latest and greatest technology when possible?

Sorry, my mistake. It is probe screen 2.9 from verser-git.

But I have similar problem like Marcodi:

So whenever you are inside of the probe screen and you use the keyboard numbers 2-8 4-6 and 3-9. The machine starts moving in the appropriate direction without stopping until it hits a limit switch

Same happens with my machine. And also when using page up and down with the z axis.

I don't fully understand the question, but I think that a material change would be handled by the touch-off process that is normally used to re-align the working coordinates to the workpiece.
This is typically achieved using one of the G10 code variants (G10 L1 / G10 L10 / G10 L2 / G10 L20)

Just to clarify, when you say "Probe screen v2" what are you referring to?

Is this: github.com/LinuxCNC/linuxcnc/tree/master...n-panels/versa-probe

Or some other probe screen?

I think you can leave multiple tools in one pocket in the table.
You call the Tool with a T-number in the G-code, then the system checks the tool table for the pocket, and puts that number on the pocket-number.

(This is useful for using two sides of a lathe tool, for example. You would get different tool-point offsets, but the tool0changer would use the same position for both sub-tools)

I _think_ that the tabs activate once you press "accept changes" at the bottom?

Is this the serial protocol, or the 4-bit gray code?

Yes thats ok
But i can not link joint.2.motor-pos-fb to cia402.2.pos-fb
Because it is already linked :net z-pos-cmd joint.2.motor-pos-cmd cia402.pos-cmd joint.2.motor-pos-fb

Axis and halshow means that move the axis but it dosnt move.

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.
