Also, for those who are thinking "I thought those Px switches were reliable", they probabily are, the two I have on my X Axis have little dents in the front, no doubt from an impact with the X Axis! So no surprise that at least at one of them failed :)

Tony can you remount them so that the target slides over the end instead of crashing into it. ..Clive

And for my next problem.. :)

So things are generally going well but very slowly. I was nicely surfacing the MDF bed of the machine but saw one of the ball screws coming away from the coupling so a good spot of tightening up was carried out and I am much more confident that wont happen again. Having created infeasible amounts of dust and also realised that the Cambam feed was set way too low I have paused to consider some options. Firstly the dust is a problem so I've got some parts on order for a cyclonic dust extractor into my Aldi ash bin and I think I'll be OK to machine some acrylic for a dust shoe but I digress...

I thought I'd add tool auto height. I read the threads, set up the inputs and did the wiring which (as its probably) relevant was just two wires from the BOB input to a set of crocodile clips one for the tool for now and one for a little plate. All was well and I tested it by touching the probe to the plate in my hands to make sure the Z retracted and it did, ... the joy :) so then the real test and as soon a I connected the crocodile clip to the end mill in the spindle the Pilz tripped out. Not the RCD's the Pilz. So, I guess its an earthing issue but without me having to draw up a wiring diagram, has anyone experienced this type of thing before? Thanks in advance chaps.
