Most of the time one of two things are happening either chips have built up under the saddle leaving the drive under some load at that point or the hard stop whitch on a fadal is a long rod with a stack of belville washers on it has gotten out of adjustment and is in contact with the slide before it hits the end of travel.
One other possibility is that the machine was cold started out of position and the center of travel is now off- Fadals do not have limit switches on the ways and travel is software set by the cold start function, which can be performed anywhere in the range of travel for the machine; IE if you cold start your machine with the head down too close to the table you will have a crash when you attempt a tool change |
