I am troubleshooting the board. it would be helpful to know the expected resistance between 3.3v and ground. I only measure 53 ohms between 3.3 and gnd, which seems low, possibly a short. i have included an image. as for the end stops, i am using optical end stops, which i have wired correctly from instructions on the wiki. i can trigger the endsops manually and the board is not effected. when i run g28 however, the board seems to experience a software crash. it is very strange. it seems that it only crashes when the board is "looking" for an endstop input.
