i would need help, i would update my CNC to an arduno uno tablet because i will also use the laser module in Mach 3 but the laser does not sound as it should.
I get stuck when connecting stepper drivers to the arduino.

My driver

But here's a problem that I don't know where to tie a thing to.
On which pin on the arduin I bind STEP, DIR, EN, and + 5V

I can't find myself anywhere on the net, but I don't know too much either, the current controller has the same marked outputs.

Here is a manual from the drivers,

thanks for the help
