Proximity switches or limit switches

Point taken I'l change it when I put it back together. If what you say is a possibility of happening then how do we guard against other things getting damaged like BK / BF bearing blocks? Is it therefore wise to leave a good margin of rail / ballscrew for stopping distance?

Well BK/BF blocks are not easily damaged so wouldn't be too worried about them, stepper motors will stall before doing any damage. However, if you have anything that can be damaged then it's best to fit Sturdy bump stops after the limits. Skateboard wheels work well.!
