Hi Jean,

Agree with Doddy and Kitwin that pull up resistors are indicated and should be fitted - but haven't seen any mention about shielding of the spindle wiring? You mention limit switch wiring shielding, but not spindle?

If its not already, I'd recommend making that shielded too in order to reduce the noise output. Also be sure to ground your shields at one (and only one) end.
