Error Printer halted. kill() called! HELP ME

Hi,

I have RAMPS V1.4 hooked up to an Arduino Mega (that was an anet A8), I've some issues with y axis of my printer (like in this video), and I tried to resolve that changing the current in the axis driver (DRV8825). Then I tried to send G28 to homing and this error was showed:

Any suggestions?

I would measure the V-Ref voltages on all DRV8825 drivers then post the results.
It does not appear that you are on the Y-Axis End-stop, though would still test all end-stops using M119.

All endstops work great, I'll report my driver vref for each axis:
- x axis: 0,14 V
- y axis: 2,13 V
- z axis: 1,57 V

Ok???

What are the specs for your Stepper motors.

Current Limit = VREF × 2
So, for example, if you have a stepper motor rated for 1 A, you can set the current limit to 1 A by setting the reference voltage to 0.5 V.

Sorry, I've been busy in these days. I'd share the steppers specs:
- Nominal power = 14W
- Nominal tension =3.96V
- Rated current = 0.9A
- Phase = 2
- Resistance = 4.4Ω ± 10%
- Temperature increase = 80K Max
- Insulation resistance = 100 MΩ Min. , 500VDC

you can hear there is plenty of current, issue is something else.

I would guess a broken wire between stepper motor and stepper driver.

Have you does basic tests? (before you try homing)

ie move X left and right with gcode or lcd., does it move left and right correctly?
move Y back and forward, does it move back and forward?
move Z up and down, does it move up and down?
and check endstops work with a M119 and manually test each end stop by sending M119 while not triggered, then holding down endstop with finger send second M119 and confirm it changes from open to triggered for every endstop.

Your error log shows G28 Z0, so it is trying to home Z, nothing to do with Y at all.

Before homing, I've done other tests with steppers and endstops but all worked perfectly. Only when I send the gcode for homing, the printer logs this error

while powered off move X and Y away from endstop

home each axis individually

ie Send machine a G28 X, verify if X homes
Then try Y with sending G28 Y, verify Y homes.
Then try Z with G28 Z, verify Z homes

also check your homing feed rates in you Configuration.h
eg
#define HOMING_FEEDRATE_XY (100*60)
#define HOMING_FEEDRATE_Z (4*60)
