z axis doesn't stop on the endstop

hi.

so i have a prusa air, sanguinololu 1.3a with marlin.

on the firsts tests the z axis was the only one moving right, and showing no problems homing.

after i fixed the x and y, now the z does move right(negative down, possitive up) but it does not stop when it hits the endstop.

here is my configurations:

// Uncomment the following line to enable CoreXY kinematics
// #define COREXY

// corse Endstop Settings
//#define ENDSTOPPULLUPS // Comment this out (using // at the start of the line) to disable the endstop pullup resistors

any idea on solving this issue?
did i mess up some part off the configurations?

A first check whould be to look what the endstops report. M119 or M200, depending on the firmware in use.

i´m using pronterface.

so i did that check:

>>>m119
SENDING:M119
x_min:L y_min:L z_min:L
>>>m200
SENDING:M200

what can you tell me off this reading?

The min endstops are all returning L (low).
Try depressing the endstops by hand and rerunning the M119, if they are working they should change to H (high)

x_min:H y_min:H z_min:L

the z did not return H. is it broke or a configuration problem?

Most likely a bad connection to the endstop, since all three should be configured the same in firmware.

ok. i will check up the wiring..

lets see if i can fix this tonight!

this problem was solve! tanks for the help.

it was a code problem after all...

i had this:

//#define ENDSTOPPULLUP_ZMIN

tanks for the help!

Now off to calibration!!
