Did not find list of kinematics module but. Do not think this kind of
kinematics module exist, scara however come close and so could be a good
starting point.

Do not think cloning is a good idea since it is an exact
storing seems to work great, though did not yet commit any changes back
the other way.

There are also some kind of auto tune function in Linuxcnc, what kind of update
frequency do you get them using rs485?

either sin/cos or quadrature. 5000 lines and 125000 pulses per turn must be
from the 25-fold interpolation, I would expect interpolation to add much. 5000
lines per turn is in line with high resolution optical encoder from other
manufacturer, have 2000P/R but think same manufacturer have
coolant is subtracted from distance of course.

Try to keep some distance to the people hanging in the meeting at my workplace.
They sit in a relatively small room together for a long period of time so if
one of them get sick he is likely to infect the others, they also tend to meet
quite much other people.
