Hello ..

The module I bought is a "Generic" which utilizes the characteristics of L298N .

The documentation that was given to me would be the link.
http://www.learn-c.com/l298.pdf

I will follow the tip above the pin and put the results in detail.

Thanks

Can you post a close up pic of the drive? A pic where I can see what is printed on the board of each connection?
I see in that last pic a jumper "5 v enable". Do you know what that is for?
Documentation is very sketchy and I dont see a pic of your board in it.
But anyway looks like you have the wiring figured out, my concern was that if you are using enable from pport pin 3, then the drive should not have come on unless output 3 in printer port reader was turned on, and in the video, it doesnt look like it is. Thats what leads me to think that the enable jumper on the drive needs to be removed and the pport pin 3 attached to the pin nearest the edge of the board to use drive enable.
Using drive enable is just an option in Mrotate, you can leave that jumper in on the drive and not assign an output in mrotate for drive enable, but to get past your original problem during bootup, you will have to use two transistors, one on each direction input.

DaOld Man:
Im thinking the drive needs to be wired like this (before adding the pin 4 drive kill transistor).

Am I any where close to how you wired it?

Finally managed to get back to camera !
if you remove the jumper 5v enable the unit is turned off

A few more tests here, I changed the pins as suggested
The pin "Enable" has two ends, one end happens to use the same engine problem firing at startup.
Checking the "Printer port reader" pins 2-9 are in "HIGH".

I believe the solution is to use the 2 transistors, will be tested based on the design stated previously.

Hello DaOld Man !

This would be the scheme that I follow, which transitor should I use?
