I made local change to the hostmot2 stepper drivers to both send and receive
absolute position encoder style. Behaviour could be changed with configuration
parameter.
The change is simple but I am still thinking about protocol because with
interpolated position mode there is a need to set param
Nicklas ,
any changes needed , i'd like to know
should we put a repro together , might make life easier

Me is novice on EDM but it seems you know what you are doing. I got digital
outputs connected on machine this weekend and will probably be able to test
this weekend.
I have made my own servo drivers with interpolated position mode, response is
fast even though I have not yet perfected control l
Thanks Thomas , for the video , very interesting and informative too , i
learned some more lol
look forward to getting all this together

Hello
video of early iteration of edm panel in use
https://videobin.org/+fe8/jab.html
i think an example of reading the db file needs to be done soon
but a working model is better than just thinkin'
thanks

Tabs are probably a very good idea, it is easy to switch in between. Even
though my knowledge about EDM machining is very limited to to select parameter
from a file or database sounds like a really good idea, I have seen tables with
parameters in manual.
If there are any problems with the softw
good progress , i cant come up with any omissions , at least at this stage

Yes, .u=voltage, .i=current, .t=time

Nicklas
are you using theses abbreviation meanings?
.u = umschaltung or Voltage
.i = current
.t = time
re: edm.u.Sparc , is this a flag meaning the spark generator is active,
or what?
re: edm.t.On & Off , are these integer microseconds or floats?
re: edm.u.Ionization, is this a flag meaning ioni
In the m-codes you sent.
M110 set onVal and offVal while I use edm.t.off and edm.t.on
M112 set ipkval while I did not have
M198 set AtMinTix and AtMaxTix while I do not have
M199 set AdvLimVal and RetLimVal while I do not have
Output signals:
edm.t.Off
edm.t.On
edm.u.Ionization
edm
The user interface is a little bit blurred.
As is now I try separate out signals for EDM generator in separate *.hal file
similar as for spindle.
Output signals:
edm.t.Off
edm.t.On
edm.u.Ionization
edm.u.Sparc
Input signals:
edm.u.Open
edm.u.Seat
edm.i
edm.ionizationCnt
edm.sp

what is good though, is they actualy asked users to evaluate the
