Thanks for the suggestions anyway

so what do we think the next step is? Run a 3 core wire and try that instead of having them all together?

Try some different switch and if so which ones? Are Any from rs sutable as it would be handy so I could pick one up to try tomorrow.

That's what I suggested earlier but using single core wire. Capacitance acts like a time delay and that's what you are getting.
Better still use a piece of CAT 5 twisted pair, it's imunity to noise is good.

Sorry I must have missed that I will give it a try.

We'll I tried 3 core shielded the full length and no luck I actually had to set the filter higher but still had the same effect. Running out of ideas, perhaps try a short run of cable just long enough to go straight from the box to the switch? Or try a different type of switch

I'm not giving in! Just wired a short length of cable (2m) straight from the csmio to the same switch and it works perfect so I ether need to some how change the wiring or the switches.

For limits I prefer this type, mechanical with a roller arm. I assume your Home switches are close to the control unit ?

Also looking at some earlier photo's I don't like the look of your 'target' for the sensor. It looks like a stainless cap head screw, try a piece of flat mild steel instead or a large steel bolt head for example.

The home switches are all on the gantry the only or that could be made closer to the control box is the x home. The triggers are at the moment a stainless bolt in a alli washer I will try all steel now
