Negative alpha/beta direction and endstop safety

Hi,
I’m come from a Repetier firmware, and in the smoothieware i’m finding a strange behavior…
My printer is a CoreXY, and in Repetier i can set the max X and Y length in mm, so the carriage cannot go over a certain value and this prevent to damage my printer…
Also, if i try to go in a negative length value, after homing, when the relative endstop is pressed then it stop the carriage…

I’m unable to get the same in smoothieware….
I’m unable to find a max alpha and max beta value, just the max length during homing…
And also i’m unable to get the endstop working as repetier. I’ve try to enable it as limit:
alpha_limit_enable true
beta_limit_enable true
gamma_limit_enable true

But if an endstop is pressed now i have to reboot my printer…
It’s very frustrating when i have to move the carriage from the Jog menu, and i have to check the movement 10 time before do it for prevent to damage my printer…
That’s also very dangerous because if the slicer is not very well configured and it create a gcode with an object out of the real bed plate, the printer will be damaged…

I’m missing something?
I’m missing some configuration?
