180 is a boatload!
i used the 72 i/o ( 3x8255) thai pci but it was pooh poohed here
despite it works for me with pull downs.
from futurlec
maybe he could use a plc,
maybe automation direct aka Toyo
as most i/o wont need realtime,
i think ( underline!) that, at most, 'wait till completed' code
gene, sorry for your experience
for me they just worked using a 8255 driver from ancient emc2.
i did have to use pull downs and it can be found in old mail archives.
another member said they didnt work for him, but that member did not try
the resistors
or did not to my knowledge.
lemme know in a

e edm
base is sable2015 from taiwan
stepper
position loop control with HAL
positioning between different cuts by linuxcncse gen
real pulse generator with on off peak current
115Vdc open voltage
blah blahblah
just so you can see real edm in diy environment

sorry pete niklas
grab the POCO EDM MANUAL from internet
it shows fequencies ( or on times so you calculate )
off time is really dpendant on flushing conditions
on time causes rougher finer surface finish
so there is frequency but frequency is a result not a determinate parameter
examples
roughing
Nicklaus hello
even tho the average velocity is low
it is important to move to the correct position as soon as possible
if the tool is too close
it will cause thousands of bad discharges per second
and damage the stock
( velocity is NOT important, position IS important)
if the tool is too far away
