Come to think of it,
You tried to find the solution near the switches. Wouldn't it be more obvious to try to solve it near the source of the trouble?
Maybe putting more ferrite cores close to your spindle? Is the spindle earthed, like maybe the rest of the machine? If it has a steel / aluminium case it probably should be?
I know my spindle has a plastic casing, so no shield there!
