we have a mazak qt 250 and an older mazak qt. both machines' tool eyes are broken. i takes a good amount of time to teach the tool manually, because we dont really konw what to touch the tool off of. and once we get close we have to tweak it in little by little.
we have to touch the cast part , a known dimension, to teach x and y, and most of the time we are inches off.
if anyone know a quicker way to teach a tool please let me konw thanks
