Adding a GO/RUN physical button to run the MDI command typed in the command line

I don't know what's wrong with your enter button, but normally it should work with the enter button:

And so IMHO it does not really make sense to have a hardware button to send MDI commands which you need to type with the keyboard.

How is the behaviour on your machine different from that I have shown?

I may be totally wrong, but I think when using M3 for the first time in MDI after startup, you need to give it a speed (M3 S400). Afterwards, that speed is assumed.

Weird one here. I have three physical buttons on my control panel connected to halui.spindle.0.forward, halui.spindle.0.reverse, and halui.spindle.0.stop. These are working normally.

But if I type an M3 or M4 command, I get no spindle rotation. It was working before, and just stopped working abbruptly. I would have expected the external buttons to trigger the same signal path as M3 M4? Any thoughts what I need to be looking for would be appreciated.
Cheers,
Mark

One of the 7i84 cards is detected and shows all pins, with both field power (power over the RJ45) and power over the VIN pin present (not at the same time, obviously), but it gives a low-voltage error and does not seem to actually work. The second one I cannot get to be detected at all.

I really need multiple Smart Serial cards to be detected for the system to work, and on the 7i92/7i85 I can only get Smart Serial channel 4 to detect anything.

I used the mill for a couple of hours today with my firmware in the pendant. I tried my best to cause some issues, but no disconnects from the dongle nor any other issues as far as I could tell. To be honest, I'm surprised that it works this well already.

I found a sticker with version information on the back on my pendant (underneath the rubber):

The top row is the firmware version and the bottom row the hardware version, I believe. And the RX should be the dongle, because there is a V09 marking on the main board (underneath the RF module).

And I attach a couple of photos from the dongle as well, in case somebody wants to compare. Not the best photos. I took them through the microscope some months ago. And right now I have a thousand wires connected for debugging, so not possible to take good photos at the moment.

Do you have field power connected to both 7i84's?
I would forget PNCConf for now. If you have the 7i92 communicating with LinuxCNC, then open the HAL show, and see if you have all the pins available on the various cards.

Hello,

the forum was indeed down during the weekend, no problem. On the first run of your configuration I forgot to remove the limit switches, the hand wheel and the MDI commands. Then I removed all of them but still the same result. By the way, I also switched the HOMING_METHOD and DISPLAY in the .ini file.

About the emergency stop - the motors are not mounted on the machine, they are on a stand and there is no danger of hurting anyone. Thank you for pointing it out.

Attached is the entire report when I run the LinuxCNC and the edited configuration files.

Oh, also, my braking/release signal is a single one for all 3 XYZ drives. Is it possible to try and separate them electrically? Most likely. I'm not sure that's a good idea, though.

Now I'm wondering if you are looking at the correct thing
is there anything in the electrical diagram as "Z achse bremse"?

I release z axis brake 0.2s after motion.motion-enabled and it works with my simodrive,
when does this servo power on signal becomes true? are you sure you are not releasing the brake before pid is working?

I don't think this is the issue. I checked just now to make sure. With me pressing F2 (which is also linked to the CNC ready signal going from the Mesa to the drive), I can clearly see the PID enabled and also motion.motion-enabled.

My AC power on button and circuit is separate from the Mesa entirely in an attempt not to have to reverse engineer the emergency stop, which is on the same board originally.

So my startup procedure is essentially:
LinuxCNC startup, LinuxCNC power on (F2), manually pushing the servo AC power on button, a signal returns to the Mesa board from the drive when AC power on is successful, that signal is linked in HAL to the brake release after a short timedelay.

In many cases, this works just fine. In many, Z falls through. Sometimes after a slight delay, so just when you think it's started up properly and the servo is holding the motor, it still falls through 10 seconds later.

Thanks for the suggestion, though!
How exactly is your servo AC power on handled? My Simodrive is sort of old, as you may see — the servos are 6SN1118-0AD11-0AA1 and the control board is 6SN1121-0BA11-0AA1.

mine are from 1992 (mill) and 1997 (lathe) and judging by the pictures your simodrive looks like new compared to mine, but I had both power supplies repaired and also main spindle drive for lathe and Z axis drive for the mill
red led H1 axis fault is on page 83 and 84 from documentation
adegis.com/media/asset/eb8a4b2af69aebb3f...84e8f10fe17ff0ed.pdf
you can try swapping z and x drive motor connection (and encoder wiring and everything else) to see if it's not your drive that is failing
you said linuxcnc doesn't know that a fault occured so you don't get following error in linuxcnc??
I first power everything, then F2 only sends enable signal to the drives
