ya i have done all that.
i ping the card
i do a mesaflash -- device 7i96 --addr 10.10.10.10 --readhmid
and i get a pin out.

That is good, no need to reinstall anything.
Did you check the motors if they lock in place when you power the drives?
Try turning them by hand, they should not move.

Just saw another post with similar Ethernet symptoms

The "avahi" error happens when you have not set a static host address

my hm2_eth board_ip 10.10.10.10 is attached
along with the my hal and in files
so it appears i have fixed the network issues , but no motor movement. i can move the joints by hand with enough pressure. I am going to check my wiring diagrams. I am making progress anything else you guys suggest ?

One more thing, in hal you have stepgen 01, 02, and 03 in use, so the drives have to be wired to outputs 2, 3 and 4.
Also setting the step_space and step_time in the ini file to 15000 would be nice to be sure the drives can register the steps, later you can lower that a bit.

Yes, the network is correct. The motors should be locked and need a lot of pressure to move them when the drives are enabled.
If that is not happening, something is not right with the drives, or the Enable inputs are inverted, if that is possible.

Another thing to check, the DIP switches, make sure that they are all off except 7 and 8. If they are reversed you will have very low power going to motors, so it would be quite easy to rotate by hand.

i took out my electronics box and moved to a test bench. I was reviewing the stepgen 0,1,2,3 orientation on the the mesa 7i96,
my wiring was the following:
stepgen 0 = z axis
stepgen 1, =y axis
stepgen 2= x axis
stepgen 3 = y' axis
hoping it would do make a difference i changed it to this
stepgen 0 = x axis
stepgen 1, =y axis
stepgen 2= y' axis
stepgen 3 = z axis
while i was checking the DIP switches, they are correct. i bump the wiring on the x axis driver, and fried it :angry: ,lesson learned .ordered a new one. I have a set of KL 5056 to continue testing.
i did notice those 3 output light up when theres nothing leading to them. not my intentions to have them in used
i did update the hal and ini files with pnCconf. and adjusted the step_space and step_time in the ini file to 15000
will up date in a minute

Tommylight, so i've been trying to figure this part out what lines in my hal file or where do i go so i don't have to wire the drivers to outputs ?
