Seems the scalar in limits.c does nothing BUG? #959

Hi;

I have a COREXY plotter; and have endless issues getting it to home. It homes successfully if I position the head near to the X- and Y- end stops. However, it seems the scalar within the limits.c file is not being applied. The travelling limits is X about 220mm, Y about 350mm. If I position the head @ eg. 150X; 200Y; and initiate $H, then it moves a few mm, and nothing else happens. When it is positioned close to the switches, eg. 10X; 20Y; then the homing is done as what is expected.

It seems the scalars used for the seeking/probing of the end stops on each individual axis is being ignored.

Can anybody perhaps help????

Are you sure the steppers aren't stalling? To test, I'd slow the acceleration and velocity parameters down ($$).
