Yes, Mesa can repair these cards

if they out of warranty, there is a nominal
change for chip replacement, usually $35.00

If these are not is the US, its probably cheaper
to repair locally due to shipping costs.
 

My bad. I had a brain fart. It is working in the dn, up position. I guess i lied, the thing that changed was the jumper postion. It slipped my mind i was messing with it. I guess thats what i get for messing with things late at night. I forgot i messed with it. This site is amazing. Most problems with these boards are user initiated. My question still stands; is it possible to get these boards service if something does go wrong with them? Not that i need it now but knowing the user (me) I am sure i will mess thing up at some point and need it serviced. I am just going to quit messing with things.

Maybe you can find something in this old thread www.forum.linuxcnc.org/24-hal-components...b485-to-huanyang-vfd
at least to make sure the communication works.
It was a long time ago this so I doubt I can answer any questions.

Are the axes moved by hydraulic motors or cylinders? Or, are there electric motors for the axes? Is it really an NC mill, or is that Ljumo just a digital readout?
Driving a machine with proportional hydraulic valves requires "dither" to be added to keep the valve freely floating.

I'm not to sure what you mean by the cloud ? You have to change the address to 10.10.10.10. once changed, ping the address and see do you get a response (and how long it took).

All the green led's light up

Are you saying the 4 green user LEDs all light when you start LinuxCNC?

That suggest communications are working

What does

ip a

report?

And what are the RJ45 LED states when the Ethernet is connected
and when not connected?

 The
red light just continues to blink with the jumper in the up, up position and none of the green leds
with light in the fallback mode. Ping is unreachable in up, dn and and in up, up.

Note that UP,UP is fallback at 192.168.1.121 and UP,DOWN is BootP
(DOWN,UP would normally be 10.10.10.10)

No idea if this helps KWorm, but 7i97T (not aware of 7i97S) is the same functionally as 7i92 with 7i77, probably some IO pin names are different.

Hi tommy. They are ac servos all connected to the same 240v supply. Would the tuning be done via lunuxcnc or on the servo amp? They are step and direction drives. Thanks

Have a look at carousel component included with LinuxCNC:
linuxcnc.org/docs/html/man/man9/carousel.9.html
And posts on this forum regarding it
www.google.com/search?q=carousel+site%3A...sclient=gws-wiz-serp
Also, there was similar functioning system on those small lathes, forgot their name, but there are plenty here...

I will take the covers off and give this a try. Thanks man.

Something does not add up, google shows many of the same model machines with manual controls
www.google.com/search?q=knuth+wf5nc&num=...mgdii=EVvF2wH31GoAHM
So upload some pictures of the machine.

Also, are both servo drives powered from the same power supply?

I'm having the exact same issue. Everything worked fine yesterday and i came out today and i have nothing. All the green led's light up and locks in the on position when i try to start linuxcnc. I am adamant about ESD and EMI. The Mesa 7i96s ground is connected to earth and all my wiring is double shielded with no ground loops. Is it possible to get this board serviced or is i a doorstop now? The red light just continues to blink with the jumper in the up, up position and none of the green leds with light in the fallback mode. Ping is unreachable in up, dn and and in up, up. I am at a lose. Nothing changed except the date.

I had similar problems with my servo system, and solved most of it by tuning the servos better. A loose servo control loop will look precise and accurate, until you put it under load. Can you rotate the servos by hand, at all, when they should be "holding"? If so, retune them.

Yes, I now have the estop working as you specified and have verified that it stops the machine when the button is mashed (OPEN).

I'm on to getting my HY_VFD spindle hooked up.

Thanks to all who have helped on this issues.
