Hi Everyone
Im from South Africa and have my Bridgeport now for 3 months and im overaul very happy with the machine but because the previos owner did not look after the machine i get wierd problems evry now and then, my latest problem is when i start the machine up and it goes through the set up routine it just goes over the Z axis and then i get the erroe ¨ wrong reference point¨ and the machine stops just there...any idees?

Regards
Jan

machine has 2 wire, a nc and a no on the z axis trip dog, probably one of these is not really making contact
