Whats the relevance of this line?

hm2_7i92.0.encoder.timer-number 1

Would this create encoder timing issues?

Just loaded 7i92_7i77_7i74D firmware and I get:

7 s32 IN -1 hm2_7i92.0.encoder.timer-number

What LinuxCNC version are you running?

setp hm2_7i92.0.dpll.01.timer-us -50
setp hm2_7i92.0.encoder.timer-number 1

Will enable DPLL sampling of the encoder position
rather than raw sampling. This reduces the sampling
jitter from as much as a few hundred usec to 250 ns
or so.

The first statement sets DPLL timer 1's sample
time to 50 usec _before_ the nominal read time.
The next statement tells the encoder hardware
to use DPLL encoder sampling rather than
raw sampling (the default timer number of -1
selects raw sampling)

I am 99% sure I also don't have that and have been # out setp hm2_7i92.0.stepgen.timer-number 1 since it was creating errors. That could explain my 5ms delay from encoder response, or part of it.
