i cant run any jop after homing or move the printer

Is this a new build or did it print before? If it is new printer, the M119 command will show what your electronic think your endstop switches are reading. If the controller thinks that they are triggered even when they are not, it will do strange things like only move in one direction or not move at all. This is where I would start, since it frequently happens with new builds.....

Another common mistake is to accidentally miswire the homing switches so that you end up connecting 0v and 5v together when the switches activate.
This can make the electronics crash when homing. So check the wiring to your end stops is correct.

m119 before homing :x-open y-open z-open
after homing : x-triggered y- triggerd z-triggred

Well, at least we know that it isn't the endstops. How about M114 (get current position) from home? It should say X=0, Y=0, Z=a_positive_number_well_above_zero. If it thinks that Z=0 when homed, then most firmware will not try to move the effector any lower because it believes the hotend is on the bed.

I don't recall what firmware you are running, but another gotcha is that some of them will not do a "dry run" without an extruder configured, thermistor working, and in some cases not being up to minimum hotend temperature.....

X=0, Y=0, Z=0 is what you should read with the nozzle touching the center of the glass. As you lift the nozzle, Z should get larger. If you ran that M114 with the carriages homed at the top, Z should have been whatever your build height is, not zero!

You didn't say what firmware you were running, and there are different ways to set Z_MAX depending on which version/fork you have. Here's a clip from an old Marlin config that I had at one point:

//Manual homing switch locations:

#define MANUAL_HOME_POSITIONS  // MANUAL_*_HOME_POS below will be used
// For deltabots this means top and center of the cartesian print volume.
#define MANUAL_X_HOME_POS 0
#define MANUAL_Y_HOME_POS 0
#define MANUAL_Z_HOME_POS 250 // For delta: Distance between nozzle and print surface after homing.

Newer firmwares support setting this with M665, M666, and/or other G-codes.

Another thing that I have seen pop up on occasion with 8-bit firmware is that the EEPROM settings get corrupted. Don't know if that explains the weird counts in your M114, but it may give you something else to search the forums for if all else fails.....
