Hi to all
I have read all the forum
No one has ever had this kind of problem
I'm shure my problem does not interest the forum
please, Mr Jerome, tell me the way to send you mails
without "stressing" people on this forum
I think only you can help us
So this is a "one way" conversation
Sorry to all ...

Hi Jerome
pleased to meet you
We have an homebuilt stepper driver , it needs only
usual inputs: step & direction
No external timer
We use max xp dll ( on a winxp PC)
We have some problems with manual motors control:
everything seems OK with both motor coupled,
but it runs for a much lower distance ...
