I think Andrew has the best solution now as maybe he maybe would need a hole in the table to do as you suggest.

I went through 4 different Z builds on my mill so i know the frustration after a lot of effort it is all in vain.

Like the amp meters in the control box, i would like to see an Estop placed on the machine when the wiring is finished, in case the worst happens.
