Hi Nicklaus:
Someone more knowledgeable that I will need to tell us about the pulse
generator frequencies that are used under various burn conditions. I am of the
opinion that the servo response does not need to be faster than that pulse
frequency.
Can you tell us what costs are of servo control at 1kHz and 40 kHz?
Hardware or processor time costs?; proprietary versus public domain software?
While sinker EDM primarily uses Z motion, it is by no means exclusively Z
motion. Many projects use the other axes, either part of the time or all of
the time. The motion control for all the axes needs to be equally responsive
as long as one or more users operate on more than the Z axis. AFIK Z-axis
only motion is appropriate for hole popping EDMs.

I have a choice
between 40kHz servo thread inside driver or linuxcnc 1kHz
servo thread. For z motion only choice is simple but for
motion of several axis/joints for example wire EDM?
