Giant 20' x 3' x 2' router build

I have now earthed every thing together and it seams to have improved it in that the filter can now be set a lot lower however I still have the same problem. I did all so find one ferrite ring I put onto one of the signal wires at the control unit end but that didn't make any notable difference. What the best next step to take try some better switches?

Set up the soft limits and slow zones, section 10.8 of csmio manual I'm looking at.
Mach3 General Config, try 'Home SW.Safety' in both states to see what happens.
Follow csmio manual section 10.11 and go through Mach 3 settings as shown.

Will take a look at that, just to let you know I have separate home and limit switches

I took a look at all of the above and no luck so I have just taken a new switch and wired it straight in to the csmio and it would appear by just testing it by hand it cure the problem which would suggest that perhapsthe switch or the csmio doesn't like the long cables !

long cables generally add capacitance and that will affect the signal, you can get low capacitance screened cable if you do a search.
As an experiment use some single core unscreened cable and temporarily wire the switch back to the input using that.

It won't be the Csmio Charlie it will be a dodgy switch for sure. The Csmio are by far the best controller I've ever seen at handling noise, even my high frequency Tig welder doesn't bother them, no other Card I've used could handle this amount of noise.!

To test I've just connected one of those cheap prox switches to a 100mtr drum of cable which I put next to my VFD running at full speed and worked fine so i'd be changing the switch.

What kind of cable ?

[charlieuk]

Yea my guess is the Chinese switches too! Can you recommend any good ones? I looked on rs components but couldn't tell the difference they were between £20-50 each though! Would love to get some to try before the weekend though as tony is coming back down from Leicester to help tinker with it on sat. In the mean time I will swap the x limit swich and see if it's any better but I have a feeling they all need to be swapped to better ones

What kind of cable ?

3 core CY same stuff I fit on machines and same stuff Charlie got on his machine I presume seen as I told where to buy it.?
