I have an A4 machine which I am using to gain CNC experience. It has trapeziodal screws and the Z axis is a 10x2. This has stripped the thread twice on the delrin nut and I have just realised that it is probably due to the 2mm pitch thread not being robust enough to withstand the Z axis hitting the upper limit of travel. This was demonstrated when a faulty new keyboard (Thanks ASDA!!!) had a stuck page up key.

The question is - Can I configure Mach 3 so that the Inductive Home switch at the top of the Z axis also inhibits further upward movement ?

You may appreciate that I have no machine at the moment to experiment.

Cheers,
Rob
