No motor movement

[chieftain0]

Hi, I tried building drawbot from the tutorial. Unfortunately motors only vibrate. I rechecked hardware (swapped CNC shield, couple of arduinos, drivers, motors). Apparently, the problem is software based, since with simple movement code everything works. I tried using other versions of grbl (deleting libraries of previous ones first ofc).

Solved the problem by moving grbl libraries from arduino folder in program files to libraries folder in "my documents". However, still no movement occurs when i connect endstop switches
