Subject: [Emc-users] 'hm2_7i92.0.7i77.0.0.output-10' does not exist
Hi All,
I have a 7i92 7i77 combo driving our mill. I flashed it with servo stuff when
I installed it. My son and I had been milling parts for a few days. This
morning when I booted up I got a strange error and by power cycling the mesa
boards, everything came up fine. We were running for a few hours and after a
part and tool change we got a joint following error and it turned out that no
joint would move. After recycling the mesa power I could move joints, but in
less than a minute, errors, like serial errors and timeout errors. So, tried
it again and now I could not bring Linuxcnc up. It got to:
hm2/hm2_7i92.0: registered
./hm2-servo7i77.hal:95: Pin 'hm2_7i92.0.7i77.0.0.output-10' does not exist
Shutting down and cleaning up LinuxCNC...
I have a feeling it is the 7i77 from what I've read, the serial port on the
board died, but I don't know how to check it. This setup has been running
fine for some 5 years.
So I was just going to order a new set of boards this morning, but they are
out of stock! I see there are other board that might work, but I'm not sure.
Thanks for any help.
Best Dan.
I would first verify both the 7I77s 5V supply voltage and Field I/O
voltage. Issues with either will cause loss of sserial communications.
Also check the cable connections between the 7I92 and 7I77.
Can you list all error messages? Starting LinuxCNC from the command
line will allow all the error messages to be looged on the console
where they can easily be copy-pasted
