Hi Jonboy,

Welcome to the forum.

Presumably your inherited machine is a 'Router style' - do you have any limit switches fitted to the axes ?

Hi Jonboy,

Although I do have limit switches fitted to my machine I never use any homing routines.

Basically each job is set up individually and for repetitive work a jig is used so that each blank is placed in the same position on the work table and just the first one in the series has to be zeroed.

This is just a suggestion, but if it is of any help to you this is the method I use http://www.cooperman.talktalk.net/files/17.htm. It would not suit everybody but it works for me.
