Hey! It worked :)
Thank you!

Now i am not sad anymore.
It must have been a bad connection. I solder shorted the 2 pins on the backside of the mesa board, then it worked.

I will be back with more stupid questions, probably. :)

Unfortunately this board has serious speed limitations, as it connects to the parallel port it is very slow and you have to adjust the Base Period Maximum Jitter according to the type of PC.
There is a latency test, which is important to check.

You need to synchronize the number of pulses from the hardware with the software. The photo below has the adjustment that increases the number of pulses.

 

The software has an initial screen to change the pulse speed. There must be a calculation for this, but I don't remember it at the moment. But you can try until you get the movement and then adjust it for the best performance.
