But thats masking any issues not resolving them.!

No, it's about finding the right product for the job, I know that mechanical switches will be unaffected over the length of cable he's using, plus I'm trying to find a solution that's cheap and easy to implement. If Charlie want's to keep going to resolve the issues that's fine, I don't have a problem with that.

Charlies wire run isn't long, it's just longer than your average CNC machine but for industry 10-12mtr isn't long.

which is why we used these connected via stanadard armoured cable, okay up to 200m according to Schneider.

. . .but what does he do then about Home switches.? . . Shouldn't have to put up with lesser accurecy by using mechanical switches.

No, that's why I mentioned in an earlier post about his Home switches being near to the control box, it would make sense to have the Home position at that end.

I'm sure the problem lies with the fact these Cheap chinese switches obviosly don't like the longer wire run and any capacitance thats coming with it.! . . . . . That or he's got some other issue he isn't aware of yet.?

That is the best conclusion now, but with fault finding it's best to start with the easy things first and in the case of DIY, the cheapest too, and I don't like guessing, it's far better to work through logical steps then we all know the 'correct' answer if it comes up again.
