Ok, I increased the step time and set it to type 0, it works, but I set everything to 10000

I would probably set the step space and step length to 5000,5000
and dir setup and dir hold to 10000,10000 on that drive.
That is, double the minimum drive timings.

When setting step 5000 5000 dir 10000 1000 the controller does not read the signal at all, the oscilloscope also the minimum signal it reads is dir 6000 6000.

Probably your scope setup
Minimum step length on the 7I76E is one ClockLow cycle or 10 ns
The 4030 drive does require quite high drive current
so you may need to wire it single ended:
7I76E +5 to Drive STEP+, DIR+
7I76E STEP- to Drive STEP-
7I76E DIR- to Drive DIR-
