you know the most of CNC machine , home point in the left bottom machine work ... now machine define the point it already stop in there as machine home point .
this happend when i press home push button in this position .

Your ruler or lineaal, it's an magnetic strip by which the machine defines where it's actual position is,(x,y,z axis) maybe a little dirty.
The machine, sometimes, can give some strange side effects like running over referencepoint or will give a referencepoint reached while it has not.
Just clean it up & it will work again like before.
If your machine has heidenhain onboard you can try this (keep the feedrate to < 5%, crashes are possible on a dirty ruler) ;

hi
r u meaning sensor ?
what do you mean of ( lineaal ) ?

[Ghallow]

Lineaal is the part called in Dutch, i don't know the English word for it,
I translated it with an online dictionary where it was translated to ruler in English if this was an correct translation i don't know.
It could also be the sensor attachted to this ruler.

I think he is refering to the linear "scales" on each axis

no no no
sorry but thats not the problem.... i forget to tell you machine is working good ... but just no move in X axis when i press home boutton ... but X axis moving in jog mode and automatic mode good .
i think may be it hardware problem ... what's your opinion ?
