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
Hi Peter,
Thanks! I didn't know the 24 volts was required. I had only checked the
5 volts for noise. That was from the command line but all the stuff above.
..hm2/hm2_7i92.0: registered..
Was clean.
So, sure enough, no 24 volts! So I'll have to hunt down why that went
flaky. It comes from the rack of the original machine. Very well built,
but it is old.
Best, Dan.
