Using a proximity sensor as a tool height setter...
« on: April 02, 2015, 10:02:29 PM »
I'm thinking about using a npn proximity sensor to set my tool height.

I'm using a 1.5kw spindle on a cnc router table and the tool is not grounded.

Has anyone successively done this?

Thx.

What do you mean by a proximity sensor?  There are several types, magnetic, optical, etc, usually they would not be nearly accurate enough IMHO.  Much easier to have a big alligator clip with which to ground the tool when you want to set its height.  Take it off before you start the spindle!
