Field power needs to be on before LinuxCNC starts (or when sserial run is asserted)
What version of linuxcnc are you running?, this is starting to look like a software bug
I have one other customer that complained of sserial errors when they upgraded from LinuxCNC 2.6 to 2.7
Also you still have latency issues:
Code:
In recent history there were
[ 909.302992] 1785490, 2023889, 1677095, 2010834, and 1898449
[ 909.302994] elapsed clocks between calls to the motion controller.
[ 909.303006] This time, there were 2074303 which is so anomalously
[ 909.303009] large that it probably signifies a problem with your
[ 909.303011] realtime configuration. For the rest of this run of
[ 909.303013] EMC, this message will be suppressed.
If you are running a 1 KHz thread this is about +- 118 usec ! ( I dont think this is related to the sserial error though )
Can you post your hal and ini files so I can try and duplicate this error here?
