It was acting correctly but the finished back off may not be far enough as I am getting this error now.
 
here are the setting for the Z aixs
HOME_OFFSET = 0.20000
HOME_SEARCH_VEL = 0.050000
HOME_LATCH_VEL = -0.016667
HOME_FINAL_VEL = 0.0000
HOME_USE_INDEX = NO
HOME_IGNORE_LIMITS = YES
HOME_SEQUENCE = 0
I am getting this error too below is the latency test I ran

Ok. So it is homing correctly. image missing /media/kunena/emoticons/smile.png

The joint.2.following error is a different problem. Can you post the hal and ini files you are using

others will chime in  about the latency  problem.

"setp hm2_7i76e.0.watchdog.timeout_ns 5000000"

and a watchdog has bit error means a worse than 5 ms
delay has happened in communications (which can also cause all the other errors)

This may be an Ethernet setup error or a hardware error of some kind

To narrow down the cause:

1. Can you ping the Mesa card (ping 10.10.10.10) wait for a few hundred echos and post the result here
2. What PC hardware do you have?
3. What Ethernet device to you have?
( lshw | grep -i eth )

The Dell 790 has an Intel MAC so needs the Ethernet driver instructed to
not coalesce packets (wait in the service routine for additional packets)
This is done by setting the "rx-usecs" coalesce parameter to 0

You can do this temporarily with the command:

sudo ethtool -C eno1 rx-usecs 0

(you may need to change the "eno1" to your Ethernet device name)

This should improve the ping times markedly but will only persist
until the next reboot. to make this change permanently, it best to edit
the interfaces file as described in the hm2_eth manual page

man hm2_eth
