if(digitalRead(ENDSTOP_PIN)) Serial.println("blocked."); else Serial.println("open.");you could have
if(!digitalRead(ENDSTOP_PIN)) Serial.println("blocked."); else Serial.println("open.");It looks like C, so I'm assuming the NOT will work correctly. If it doesn't, you could just switch the contents of the if and else blocks.

Also, what exactly is the function/purpose of the diodes? Is it to make sure that a current doesn't flow from the motor back into the chip and fry it?

Why do you say "wiring leading to the stepper"? Isn't the DC Motor Driver used for the extruder DC motor (GM3)?
