A couple things:
loadrt probe_parport
should probably only be inserted for RTAI (and maybe only on EPP configs)
It fails on uspace
PID stepgen works (tried on 7I76E, made a 5i25/7i76 config and replaced 5i25
with 7I76E and changed driver line)
if the DPLL module is present, the following lines can be added to reduce
stepgen jitter:
#add these lines if you have a DPLL module
# set timer 1 to 50 usec before servo thread
setp hm2_CARD.0.dpll.01.timer-us -50
# enable DPLL timed latching of stepgen position
setp hm2_CARD.0.stepgen.timer-number 1
with the DPLL module you can have a much higher PID P term (since the sampling
jitter is reduced by a factor of ~10 to 20 times)
P = servo thread rate works well for me with DPLL (so 1000 for 1 KHz, 2000 for
2 KHz etc)
