I'm a bit concerned about the STEP/DIR wiring.
It appears that the thick white wires are grounding the STEP- and DIR- pins
This should never be done as it shorts out the STEP- and DIR- pins
possible damaging the driver chip.
If STEP- / DIR- are unused, they should be left unconnected.

I am going to check the connection, I should have connected TB2 pin 2-4 with the white wires [ Pulse - ] [ Dir - ] from the Driver.
the pink cable from the X connector seems to enter pin 2, I need to check!!
thank you very much for the observation !!!!!!!!!!
