Hi

I have a EZRouter cnc machine which has a Porter Cable used as a motor spindle, cutting in the main, aluminium composite Six months ago it started sparking heavily and after a few weeks stopped working. We gave it into repair and was told it had been recoiled, however it has similarly started sparking again and sounds noticeably less noisier to my ear so I sense it may need to be looked at again very soon.

Can anyone recommend any repairers in London who could have a look at it as I'd have hoped and expected it to have suffered no problems for a while.
