Thank you, all of you that gave me suggestions. I had tried to reverse the logic of the endstops, and the motor direction, but not at the same time. I was so afraid of crashing the head again.
Now that I have changed those settings, the machine homes perfectly. But the weirdness continues. I tried to jog the X axis in Pronterface by clicking on the -X quadrant, but it tries to raise the X even higher, although it was already homed. If I continue to push it, the Y axis runs away toward the build platform! Doing the same thing to the Y axis, the Z axis moves!
I traced the wires and they are all right. All three carriages homed well,X,Y,Z, bang, bang, bang. I manually homed the endstops and they show "triggered" as I push them up. But it still won't move as I believe it should. I cannot calibrate the printer until I can move the effector to a specific location.
Any ideas about what could be causing these problems? I will try anything at this point.
Thanks again for all the advice.
