OK, turn out that the PX is actually behaving fine, its the other X Axis one thats dead, ran a new one in parallel and that one works as advertised so I'll just swap the dead one out. Sorry for the confusion. Tony.

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.
