Now you're worrying me. Sorry, quick reply just to suggest for now not to operate this until we try a few more things.

Please describe "get static" - normally a static shock dissipates very very quickly - an immediate jolt followed by nothing. Does Pete get anything more sustained? (lasts more than a fraction of a second)?

EDIT:

Sorry, and from touching what?

[petesos]

this is louise back and at this point very tempting

When the spindle on/off rocker switch is off nothing happens when i rub my palms over the bed of the cnc or my arms .But when i switch it to ON and i rub my hands on the same part of the bed i can feel some static but when i put mt forearm on the same place i get i good old jolt from it .If i wear my slipers there is no problem but in bare feet is when it happens

So, some of the bits of information that I'm thinking about:

Spindle On/Off appears to present power to the spindle motor. But also there's some current flow into the metallic frame of the machine - resulting in a light shock sensation. The VFD is indicating a fault with the motor drive output - notionally a short circuit, but it could be through a return earth.

I this point I'm reluctant to support you probing around because my thoughts are that the machine is electrically unsafe. There's an amount of testing you can do with the machine unplugged - but I need to ask if you have a DMM (multimeter) and are confident with the use of one. All testing will be done unpowered.

Just done a personal test on the machine and results are as follows.

To start with everything was wired up when it arrived except i had to bolt on the stepper motors.

So with the machine turned ON and like i said i get static and a shock if i rub my arms on the bed

If i disconnect the spindle with the machine turned ON i get no static and no shock on my forearms.

So this would indicate to me that it must be a faulty spindle , so my question is would a faulty spindle with these issues give a code like we have been getting

Just goes to show that us blokes are more sensitive souls.

I keep throwing the radio into the wife's bath but she never feels a thing :-( Maybe I need new batteries.
