The Mrs will be using the machine a lot when i am at work and although its a temptation to let her carry on messing with it especially the 3 phase side
i think its best to shut it down and request another spindle be sent .
I truly thank you for all your help with this matter and i appreciate the input
Thank you
Thank you all
