Charlie are you using shielded wire for the cable back to control box and is the sheild earthed just one end inside the control box.?
Also is the machine frame earthed to same earth point.?

You have long wire runs so they will act like antenna picking up any noise so you'll need to Eliminate this really before you'll get any joy.
I would also try a differant switch you maybe have poor switch with slow components giving slow reaction times.?

What do you have debounce set to in Mach3 General Config ?

Zero would this be the same as the filter in the csmio plug in or have the same effect ?

I had a read up and I think it's a similar thing however it didn't seam to make any difference at all that I could figure I tried up to 4000.

Mach De-bounce isn't used with Csmio. More advanced Noise Filtering is done in the controller thru the Plug-in.

Yes it's all shielded at one end the Ali frame is directly bolted to the floor the moving part of the gantry though may not have any sort of ground unless it can travel through the Hiwincarriages. The problem seams to effect all switches. I was wondering about replacing a switch but wire it straight to the csmio ? Would it be best to disconnect the rest of them if I did that?

Not to be trusted so run a Earth wire from both the frame and the Gantry back to the Star point in the Controller.

When you say the ali frame is bolted to the floor that's OK but it would still need to be bonded the star point. Also what voltage are you running the sensors at. .. Clive

Edit the mistro beet me to it

[charlieuk]

Had a feeling that was the case jazz

thanks guys will do that and report back voltage at the switch is 23.9/24v

Thinking about it then I really need to earth each of the axis? If so can I earth the z to the y then y to the main frame then back to the control box ?
