OK JUst a question are we talking PP or SS?? (;-) I do know that homing is control through the driver on the PP. SS??? should be on the board.

Hi TP!
I have a very simple machine, self constructed. I use stepper motors (dir/step controlled) using the parallelport. The homing sequence is full controlled by Mach3. The optos are connected to the parallelport.
It really would not make sense to do it any other way.
That is what I mean, but it does not work that way.
It is so easy to test, I can only repeat it. As long as during the homing, a acceleration curve take affect, the machine will travel on after releasing/leaving the switch. You can see, that the machine doesn't travel towards the switch again. Look at the machine coordinates. If they show zeros that will be ugly, and that is what I see on my machine. And it is not to clear the jitter area. It is not the speed of the parallelport it is the software.

that was the first thing I wanted to do, but I did not find an email adress.
