sudo chrt 99 ping -i .001 -q -c 60000 10.10.10.10

 
no se como hacerlo

   

Sorry, typo

sudo chrt 99 ping -i .001 -q -c 60000 [card_ip_address]
 

I recently installed linuxCnc on a RPI5 and experienced a number of connecting issues with 7i92, I want to share.
First step the ethernet connection to 10.10.10.10, fixed by setting the RPI5 address to 10.10.10.21 (ipconfig), this enabled me to ping the board.
Secondly and more time consuming was getting the first steppen motor (X-axis) to rotate.
Here mesaflash was the most important tool:
run: mesaflash --device 7I92 --addr 10.10.10.10 --readhmid

this reports the pin layout and for me it reported all pins mapped to None!

After this it became easy finding a .bit file flashed that to the board,
and now the pncconfig application for the X-axis got my steppen motor running.

I know this is only step one but now I can start tuning to the exact settings.

Pining the Ethernet IRQ to a non-isolated core  would have the same effect
as not pinning the IRQ at all (especially if irqbalance is disabled as it seems
to be in the standard Debian LinuxCNC distributions)

Ip address is 10.10.10.10 es un ordenador un poco viejo y la verdad no se como hacer (sudo chart 99 ping -i .001 -q -c 60000 [card_ip_address]) esto me sale not found

I managed to change the parameter for the z axis to change the poles of the motor, I slightly reduced the trimmer for ``speed'' on the driver and now it wants to turn on the power for the drivers, all the lamps are green and the motors are energized and do not turn...however, according to the instructions, it asks for the first referencing, so anything else unfortunately throws an error and the referencing will not start, I will also have a screenshot tomorrow in pdf or image format of schematics, I guess I will have to to do a retrofit

I will try this, but again this will introduce a delay. Currently when the motor disables the brake enables but there is a delay so z axis drops a couple centimeters.

The z axis motor does have a brake but there is s delay between the motor going dead and brake engaging. In that delay time the z axis drops a couple centimeters.

There is a failed power supply somewhere, for sure, so start by checking voltages, usually they are marked on the boards.
And please, please do not do that "on-off-on-off" thing quickly, that is how machines are broken, give it 5 to 10 seconds between tests.
Edit,
upload schematic here so we can have a look.

What PC do you have, and what is the result of:

sudo chart 99 ping -i .001 -q -c 60000 [card_ip_address]

Where [card_ip_address] is the IP address of the 7I96S (Either 192.168.1.121 or 10.10.10.10)

there is a schematic but very weak, I can find out which cables are for encoders and analog inputs for drivers, which is enough to maybe tune the motors, but there are a lot of inputs and outputs of some inductive sensors and the like, so the schematic is a bit useless, I would have to see what activates what. I'm worried because maybe the switch for the drivers is faulty, (see the attached video) plus x, y don't move and I had to remove the driver for z because when I turn on the drivers and hold the z axis it goes up or down quickly.

I would try for sure to keep the motors and drives.
Does it have schematics?
