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.

DMU 50M retrofit 99% done, Z axis falling on brake release

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"?

DMU 50M retrofit 99% done, Z axis falling on brake release

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

Might be cable wiring (if you never even get a green blink  from the 7I84U, there is no communication)

As tommylight asked, do you have both field powers applied ( A and B )?

Is sserial channel 2 enabled in the hal file?

(something like : "sserial_port_0=000xxxxx" in the driver command line)

Also

mesaflash --device 7i76eu  --addr 10.10.10.10  --dbname2  7i85 --readhmid

would list the 7I85 pins, not DB25 pins

Considering a Full Rewire on a Working Schaublin 125 CNC

Category: Turning

I tried again today.

At this point, I believe that at least some of the hardware is broken. The Smart Serial channels 0 to 3 of the 7i92t/7i85 combo do not work. I was able to get 4 of the 5 Smart Serial boards to be detected if I connect them to channel 4 of the 7i85, but on all other channels I get nothing. I don’t know if the fact that this is exactly the channel used by the bitfile I used to get a working config is a coincidence, or if I somehow managed to damage something.

I also don’t really understand how the process described in this topic works:
forum.linuxcnc.org/39-pncconf/52554-disc...ted-mesa-fpga#299687

With the described setup, there is no way to set the X and Z axes. When I try to go that route, I always get an error window in PnCconf telling me I have to set stepgen or pwmgen for the axes. So the statement “The rest of the setup in PnCconf should proceed in a more normal manner.” seems strange to me.

Regarding the 7i84U, I can get one to be detected, but I get an undervoltage error. Measuring the outputs, they do not seem to work when I set or reset them, and when I inject +24V or GND into an input, it does not change state in HAL Show either.

The second 7i84U is not detected at all, and LED CR6 does not come on.

So are both broken somehow? I don’t know.

At this point, I think my 7i73 and 7i83 are probably fine. Both 7i84Us are likely faulty, but in different ways, and either the 7i92T or the 7i85 may also have some problems.

I really don’t know how to proceed from here. Honestly, I am considering getting a 7i97T and more or less replicating the setup I use on my mill.

7i84 requires having field power on both section for all IO to show up, not sure about the 7i84U.
Is the field power applied to the 7i84U?

Does QtVCP zoom with mouse wheel?
Multitouch should at least emulate mouse buttons and wheel, but i never tried it... there is something for Linux enabling multitouch but i forgot the name, comes preinstalled with System 76 laptops and their Linux distro, see if you can find any info about it. I did test it on a touchscreen laptop quite a while back and pinch to zoom worked for most stuff, i do not recall testing LinuxCNC with it.
