Gene can you send some links to some of these drives/motors. I'd like to
read more about them. Sounds like interesting tech. Maybe we can steal some
ideas here. Plus if we get a control board set up and running there is no
reason we couldn't adapt it to run other types of power modules.
I don't have any book marked.
Best is to go to the hanpose web site and search for "closed loop
steppers". Or for 3 phase stuff, google for LCDA357H. 3 phase only
turns 1.2 degrees a full step but this is only a 50 volt driver I'm
using with 42 volts, 90 volt nema 17 or nema 23-34 are LC42 or LC57,
both of those can use psu's to 90 volts or more.

yessir thank you. I studied it a fair bit a few years ago. It's part of

I'd like this new board to run out of thr box linuxcnc hal and maybe we
can
port and adopt lots of the STMBL code into this project.
My goal is to have this "controller" be a bone stock hal based system
much
like STMBL except not the "stripped" down hal that Rene created. Which
I'd
assume he had to do because of processing and memory power constraintd. I
havent yet started playing with my pine star board but it should have
more
than enough power. Hopefully we can get at least a 4khz thread going on
it.
Maybe more!
What are modern servo amplifiers running their pid loop at these days?
Stepper/servo's, since two timers cost money, I suspect are running at
their basic ultrasonic speed of 22khz or better. It simply does not make
economic sense to do otherwise.

Are you aware of the STMBL project? That would seem like a very good
starting point, as it already plays well with LinuxCNC, and works with
a wide range of feedback types (Hall sensors, resolvers, encoders and
serial protocols)
In fact you could probably copy the LV board with only minor changes
(to account for component obsolescence) and make a new HV/power board.
