I just set pin 17 to flood and pin 18 to mist. Then the relays work...
So how can i set the pins to Digital out and control then via Linuxcnc. Can i create new buttons in Linuxcnc?

Firstly, I have already implemented a solution for checking the tool table . If this seems useful for others, we could consider integrating this function directly into Gmoccapy.


I would also find it useful if there were an additional option available for each tool in the tool table—for example, a checkbox or drop-down menu for the direction of rotation (CW or CCW).  This would make it easy to determine the required direction of rotation for each tool and eliminate errors caused by incorrect rotation.    

OK, I haven't seen or done that yet, but I also do a lot directly via CAM. 
In my case, it's definitely important that the tool number and the pocket are unique.

I've adapted it for my case, maybe someone else can use it too.In the settings, you can enable or disable the check and set the number of pockets.(Gmoccapy 3.4.9 LinuxCNC 2.9.6) 

ja, aber es ist von vorteil dafür eine dedizierte verbindung ohne switch/hub dafür zu nutzen, um netzwerk kollisionen zu vermeiden.

versuch lieber erstmal rauszufinden wie die belegung an deinem 25pol stecker ist und ob das idealerweise mit der default config der mesakarte zusammen passt.

Soweit war mir das schon klar :-D

Ich les mich da mal in ein paar Config Beispiele ein.

Ist das eine normale TCP/IP Verbindung, also bekommen beide Seiten eine IP-Adresse, die ich dann in der Linuxcnc Config angeben muss, damit der weiß wo er seine Steuerbefehle hinschickt?

Zur Fräse hin ist mir das klar, aber zwischen Raspi und Mesa Karte ist noch ein Interface, das konfiguriert werden möchte (wenn ich das richtig verstanden habe?)

Aber ich schätze wenn man die Teile vor sich hat, wirds klarer

Ja, dieses Interface nennt man "Netzwerkkabel/Patchkabel"

Der Raspi wird über RJ45 mit der Mesakarte verbunden

Die karten die er verlinkt hat, da kommen auf die pfostenstecker auch nur 25pol d-sub stecker drauf, also selber anschluss wie beim parport-hat und sollte somit auch ein 1:1 ersatz sein

So, jetzt habt ihr mich soweit. 

Ich denke ich probiere beides.
Den Parallel Hat weil ich dann einen 1:1 Ersatz hätte, und vor allem im Fehlerfall eigentlich nur der Raspi kaputtgehen kann.
Die China Karte weils mich interessiert, ob ich das ans Laufen bringe - auch wenns eine weitere Konfigurations-Ebene dazu nimmt, die ich mir eigentlich ersparen wollte.
Was braucht so eine Karte an Stromversorgung? Die 24V werden doch nur benötigt wenn die Stepper (+Treiber) da direkt draufhängen, oder?

Edit: Order ist raus, mal schauen wie lange die Lieferung dauert. 
 

Naja, den Rpi5 kannste ja trotzdem brauchen, war ja kein rausgeschmissenes Geld, aber weg vom Parallel-Port ist das einzig richtige und dann noch für kleines Geld

@UI
Oh, das ist ja mega interessant mit den Karten aus China, da hoffe ich sehr auf deinen Bericht

I'm glad you got something working for you. I am testing code for future ability to set resolution.

[SOLVED] XHC-WHB04B-6 on LinuxCNC 2.9.6 (QtDragonHD + 7i96S) — Beginner notes
(I am sharing the exact steps I followed, written simply. Many threads assume advanced users; I am a beginner.)My machine / system

• Gantry router XYYZ (dual Y motors), work area approx. 1300 x 1210 mm
• Controller: Mesa 7i96S (Ethernet, step/dir)
• Spindle: 2.2 kW, 24,000 RPM
• UI: QtVCP / QtDragon_HD
• OS: Raspberry Pi 5, Debian 12 (Bookworm)
• LinuxCNC 2.9.6

What actually fixed it (short version)

1. Load the pendant HAL file as a HALFILE (before the post-GUI), same as the donor machine.
2. Add MDI_COMMAND lines under [HALUI] so pins halui.mdi-command-XX exist.
3. Keep qtvcp_postgui.hal clean (only GUI signals, no pendant driver).
4. In my case, moving the WHB USB dongle to another port made the wheel/jog and DRO updates work.

STEP 1 — Copy the pendant HAL file
Place xhc-whb04b-6.hal in your config folder (the same folder that has your .ini and main .hal), e.g.:STEP 2 — Load the pendant before the post-GUI
Open your .ini and in the [HAL] section add this line and keep this exact order:Important: do not load the WHB driver inside qtvcp_postgui.hal.STEP 3 — Create MDI pins under [HALUI]
In the same .ini, find (or create) the [HALUI] section and paste this block right under it:This creates halui.mdi-command-00..07 (indexes follow the order above).
Add more MDI_COMMAND lines if your xhc-whb04b-6.hal uses higher indices.Notes so jogging actually works

• E-STOP released, Machine ON
• Manual mode
• Fully homed (for XYYZ: X, Y1, Y2, Z)
• On the pendant, use Continuous, or Step + Step size
• If the wheel does nothing or DRO does not update: try a different USB port/dongle (this was the final fix for me)

Thanks and request
Many thanks to the original thread’s author for sharing files and guidance.
If possible, could you post a short summary of the final button mapping (what each macro-N does, Continuous/Step, ABS/REL, etc.)? That would help beginners keep their configs consistent.If anyone needs it, I can share my final .ini, xhc-whb04b-6.hal, and a minimal qtvcp_postgui.hal exactly as they ended up.

10 in/sec is well beyond what we ever need; indeed, I'd be surprised if we need to achieve even 0.1 in/sec.  That was just an attempt to see if changing that value would drive the needed speed.

As for commenting out the PID stuff, that was due to the way I understood them to be only needed for servo motors, and not for stepper motors.  This is based on my reading of section 2.13.2. Servos in the manual (linuxcnc.org/docs/stable/html/config/ini...ub:ini:sec:joint-num).

Quite probably, I misunderstood the manual.

I will add the PID stuff back into the configuration and test tomorrow, and then report back.

After looking at the schematics and hal file I realized there is an error on one or the other but the estop pin I needed to get the machine to release was on tb2 rather than tb3 that the drawing indicates. I connected that so it is "bypassing" the non existent estop switch and bobs your uncle I can get the ui out of estop and mess around with pin outs and what not. I plan on editing the program quite a bit more to move all of the user controls to the 7i73 that will be mounted in the user interface box rather than running all the wires back to the main 7i77 in the electrical enclosure. I verified connectivity with the 7i73 so it should be fairly smooth sailing from here(crossing my fingers) I have ordered as many different breakout boards/connectors so I don't have to splice into the existing wiring. My goal is to have as minimal invasivity if that's a word as possible. In theory being totally reversible with no retermination of connectors. It added a bunch of extra cost but I think it is way more valuable having all the connections in tact and original.

ok here are my files and the reference file for the mh400e which was made about 5 or more years ago I think. I made a bunch of configs so I am sorry the name is the default I need to change it. again I think this is mostly working now short of a few bugs I need to test some things out and move towards wiring things to the mill
