Tower Beta Problems with Smoothie

Controllers Smoothie
1

Hi all,
I just built my Delta printer with smoothie, very happy about that,
the printer do the zero sequence properly, all the manual jog are ok, I mean positive and negative jog, plus the z axis going up and down.
So i used the macro to set the nozzle to the bed center, G28:G0Z0F3500, All good
Then the macro for the Alpha Tower,G28:G0Z0X-80Y-40F3500, All good
Then the macro for the Beta Tower,G28:G0Z0X80Y-40F3500 here the problem: the Z axis is doing just 124mm of the 250mm to the Zero position and stop with the nozzle in the right place(X-Y), but half of the way to the bed Zero point (WHAT I’M DOING WRONG?)

Then the macro fot the Gamma Tower,G28:G0Z0X0Y80F3500, All good again, nozzle in position as the Alpha, except the Beta Tower……
If i look at the numbers going into the jog page i can clearly see that the Z is stopped at 124mm instead of 0mm as it should be as the other towers.
Any help is really apreciated, thank you

What are these macros *for* ?

Just added to the custom menu and they works, except the beta tower one,
I’ m using them to calibrate the bed manually, as my frame is perfectly aligned and the bed surface is
Machined, I do not need the bed levelling routine to work.
Just to be clear, all the towers are aligned and the end stops are working at the same equal distance, (optical ones) with 0,02 error at every zero axis. I cannot ask for more.
Smoothie is an original one, not a Chinese cheap one (maker base) running Smoothieware.
Last thing, even if i put manually the nozzle to the Z0 pos. and i trigger the Beta axis macro it rise up the nozzle to 124mm and always to 124mm and only to the beta tower, i even swap the numbers from positive to negative, nothing change, is always the same at 124mm.
Is this one a bug of the firmware?(maybe?)
I tried even another smoothie from another printer, nothing change :-((
