While I haven't yet implemented all of your suggestions.  I did go back and rewire my EStop with a grounded cable like the one I connected from my VFD to the Spindle.  After doing so, I turned the Debounce down to 0 and ran a bunch of jobs as a test.  DEAD ON!  No missed steps as best I can tell!  Thanks so much for the help!

I agree.   I know it's a problem.   I don't have any limit switches setup, just 2 home switches.   But my estop wires aren't shielded.   To make sure I understand though, I would hook up the shielded wire to the estop button, the other end to my g540 and the drain line to ground on my g540?

Greetings,
Just finished my Joes CNC Evo.  Happy with it so far, but his a few snags last night.  Noticed that I had to be losing steps big time.  My circles were looking like eggs!  Yes, I have a noisy 2.2kw chinese spindle, but I have nice shilded wire and have connected the ground pin to the casing.   I have several times had EStops thrown when the spindle's not running.  Not sure what's going on, but I went ahead and jacked the Debounce up to 2000.  Seems to have fixed it to some extent.  The EStops aren't happening any more, but i was still losing steps both on X and Y (dual drive).  So after some reading, I put the Y and X on Step Low Active (supposed to help?)  It did!  Now it appeared I was only getting lost steps on X, but not Y.  So I disabled Step Low Active on X and it seems good so far, but of course every time I go to run a job I'm nervous.

LOOOONG STORY to ask this one little question.....Does anyone know of any wizards to test for lost steps.  I have 2 home switches installed, X and Y, nothing on Z.  I'm thinking like a wizard that would home the machine, then move it some number of steps out, then return it, ideally it should be the same number of steps back to the switch, but if it's more/less, it could tell you so you would know you still have an issues somewhere?  Does it exist, and where?

Thanks!!

I figured it out last night.  I had all the PD settings correct, but I didn't change the position of a jumper on the VFD.  I made a quick video showing what I did and posted on youtube last night.  If anyone finds this post looking for ideas on why theirs won't work, feel free to watch my video.  https://youtu.be/GoiXZt9_cxc

Sorry for the messy environment, but still hacking it together. 

So, the problems is fixed now, thanks for the suggestions!

Hope you find an answer.  I just posted a few hours ago an almost identical problem.  Mach3 turns my spindle on, but will not adjust the speed at all!  The VFD will change speeds if I move the POT, but nothing if flowing from Mach3 to the VFD itself.

Greetings All.
I've read up on this topic a LOT, tons of googling, Found a ton of info here, unfortunately, not the info I need to fix my problem. 

Followed the wiring here.  http://www.homanndesigns.com/pdfs/EN010_V8.pdf

The relays work.  The spindle indeed starts.  However, the RPM shows 0 in Mach3 AND it cannot control the speed of the spindle.  I can turn the POT and it adjusts just fine, but if I try to change the speed in Mach3, nothing happens.  I have setup everything according to Port/Pins info found here.  Set up my pulley and all that. 

Thoughts?

It's that cheap chinese stuff from Ebay.  Hyunyang or whatever.  I've separated them.  In fact, if I take the spindle out of the mount, turn it on and hold it in my hand, the machine runs fine.  It only throws the estop if I just barely touch the casing anywhere on the machine.  It's definitely causing it to ground out and throw the estop.  After making some adjustments that I mentioned previously, it's gotten better, but still after about 45 seconds or so when connected to the machine, it will throw an EStop.  I think my next effort will be to try the star grounding mentioned by the previous poster.  I feel like I've already done that, but maybe it could be cleaned up a bit.

Well, I ran a ground cable to earth from the spindle after I isolated it with Electrical tape.  Shouldn't that help?

I'm going to try your suggestion of grounding the Spindle and VFD/Spindle wiring shield to one point on the machine and then grounding the machine to earth.  If it continues, I'll try another circuit completely for grounding, if that doesn't do it, I dunno what I'll do. =(

No, I don't have an EMI filter.  Didn't know I needed one.  Can you recommend a reasonably priced one?

Also, I'm using shielded DB9 cables from Gecko controller to motors.
