Im curently playing around with the probing ! i have an toolsetter at fixed position , and position is saved with the menu . I used reference tool (or the tool i want as reference tool , its a 3d touch probe) after position probe was finished i hit the "save as g43 tool offset" and mdi stated reference saved Zxxx.xx . My question is , the reference tool is now set and will be used in future probings ? cant se the tool offset changed in the tool table for the given tool number . I have an ATC spindle but changer , but tool are in permanent holders so ref tool will always be the same or pretty close to when ever i mount it . If this aproce isnt right for setting up the ref tool , im all ears and need help to understand this procedure .
