I have EDM function without doubt. There is however a difference if on time is
started to count at 28 volt or lower there are sparcs but if it start at around
35.0 volt there are not much sparcs.
Main current source is turned on during ignition and I suspect there are
current flowing before on
Put a 1uF cap across your spark gap. This will allow you to test whether
you have EDM function at all.
Even a 10uF cap. It will mess with your control, but you can now get a
handle on your fluid, and typical gap.

I seem to recall that 5axiskins links to the tool-length offset, so a
change in tool length might change the apparent position of the
controlled point, whi

Is this a non-trivial kinematics machine?
I'm working on a machine that does something like this when switching
between forward and inverse kinematics (or maybe the other way around). In
my case it is caused by a slight error in my forward kinematics function.

I'm a bit confused what could cause unexpected move after pressing stop or
pause->stop.
Here is print screen what happened: https://cdn.pbrd.co/images/1X2RCHL7.jpg
Recently I implemented manualtoolchange but the only thing I was modifying were
subroutines ... not sure if there could be source

regarding 'start of period to count'
there is a concept in EDM that was branded ISOpuls and more genericly
iso-energetic
it is a method concerning WHEN to begin the on-time count.
to make each spark have same energy
the duration of current flow must be equal
so a circuit to detect the dr
I investigated further and it seems to matter at which voltage level start of
period start to count. As is now current is on during wait for ignition and
hence this period may be elongenated with a lover voltage level. Low enough and
on time will not start until a sparc happen.
I actually think
