New User problems...Linuxcnc terminated with an error was created by Simon
Hello good people :)
Complete new user here. I have spent all weekend trying to install and configure linuxcnc and a mesa 7i76e board, for a Churchill-Redman lathe (Monarch copy) conversion, with limited success so far.
I bought the 7i76e second hand, but unused. The guy I got it from originally bought it in 2014.
Card details:
7I76E
Mesa Electronics lot#13608L1
Firmware revision S14H1
UNIT = 1A000005

I have tried several installations of different iso's ,and am currently running Debian Buster 2.8.0 iso. Running on an old windows machine I had kicking around.

I have managed to get the network talking to the card, but only on the default IP 192.168.1.121, for some reason I can't connect using 10.10.10.10, the ping drops all packets, and mesaflash says no 7i76e found...

Now to my problem...I have run through the Pncconf, with a very basic step and direction only configuration, just to try and make a stepper going...baby steps...

The Hal latency test shows:
Servo thread (1ms): Max Jitter 6011
Base Thread (25us): Max jitter 12973

The test / tune axis dosen't appear to do anything, otherwise the Pncconf finishes without errors.
However, when I run Linuxcnc, it does not start, saying linuxcnc terminated with and error.

And running linuxcnc from the console I get:

This has been a pretty tough learning curve, having never used linux before this weekend. All my knowledge so far comes from this forum, and I wouldn't have got this far without it, but I am at a loss what to try next.
Any help would be greatly appreciated!
Cheers,
Simon : )

Shame you're having a issue, Mesa gear is rock solid.

Do you have the Mesa card connected to the computer directly via cable. ie not through a hub, switch or router ?

That's all I can suggest at the moment, PCW should chime and fix you right up.
In the meantime could you post your hal & ini file ? These always help in debugging issues.

Hi,
let's analyze the debug first.
You want to load this config: "my_LinuxCNC_machine.ini" with this card: "hm2_eth: 192.168.1.121:. "
The message from the debug.
"hm2_eth: rtapi_app_main: Resource temporarily unavailable (-11)"
Possible mistake:
Your network configuration is not correct and your card cannot be found.
Network card in the PC must have a static IP address and other than your "7i76e" adress.
wiki.debian.org/NetworkConfiguration
The channel is busy during operation and cannot talk to any other device. There should be no hub or router between.
To use adress 10.10.10.10 set up jumper W3 in UP position.

Common stable setup is 2 Networkcards.
In PC static address 10.10.10.1 and mesa address 10.10.10.10 with set up Jumper W3.
Second card adjust to your home network.

Thanks for the speedy replies!
Some progress!
I can now connect with mesaflash using 10.10.10.10. I wonder if my problems might be coming from Wicd network manager? I only have one ethernet card, and am using an edimax USB wifi doodad for internet connection.
Wicd only seems to let me connect to either the wifi or mesa card, but not both at the same time. I just de-selected 'automatically connect to this network' for the wifi, and mesaflash connected for the first time using 10.10.10.10...

But, linuxcnc is still not loading...I did just notice the line: "Note: Using POSIX realtime"
is this my problem? Does it need to be preemp rt kernel for the 7i76e?

Going by this
hm2_eth: loading Mesa AnyIO HostMot2 ethernet driver version 0.2
hm2_eth: 192.168.1.121: INFO: Hardware address (MAC): 00:60:1b:10:40:05
hm2_eth: discovered 7I76E-16
The driver has found the MAC and reports discovering the 7i76e.

The Op has also reported he managed to get info from the board, so I think we can assume that the PC & Mesa card are on the same network. Hopefully the wireless & wired network are on different networks......otherwise there could be an issue.

The output of
ip a
would help.

I will show two results for ip a, because I can only connect to either wifi or the mesa card at one time.

This one when I'm connected to the 7i76:

Does it need to be preemp rt kernel for the 7i76e?

uname -a show: "Linux debian 4.19.0-11-rt-amd64 #1 SMP PREEMPT RT"
You have the right one

but to start linuxcnc change into your config folder
cd /home/simon/linuxcnc/configs/my_LinuxCNC_machine
and start linuxcnc by
linuxcnc my_LinuxCNC_machine.ini
or shortcut on your desktop
But share your hal and ini. Maybe there is something wrong inside

This is your issue.

inet 10.10.10.11/8 brd

The PC & Mesa card must be on the same network.

The Mesa card can not have a 192.168.1.xxx and the PC have a 10.10.10.xxx address.


Also the wired network card must have a static address. The reason for this is that the Mesa card most be connected directly to the PC via a cable, there can be no hub, switch or router connected and therefore there will be no other device that can give out an IP address.

Technically there is no reason why the wifi interface & wired interface can not be enabled at the same time. But they must be on separate networks.

ie: The wifi would have an 192.168.1.xx address
The wired interface would have a 10.10.10.xxx address (but not the same as the mesa card)

The manual for the 7i76e is here www.mesanet.com/pdf/parallel/7i76eman.pdf and has info on setting the jumpers.
The page for the IP Address is here: www.mesanet.com/pdf/parallel/7i76eman.pdf#page=10

Set the Jumpers for "FIXED FROM EEPROM" as long as the user hasn't messed with this.
Remember to power down the 7i76e before changing the jumpers.

board fails HM2 registration

This user had the same issue. Flashing an up-to-date bitfile seems to have fixed the problem, if I get that thread correctly.
