The programmer before me made all of his programs by starting in DCC mode. foregoing the manual alignment and instead just adding notes on where to set the part on the grid plate in the exact same location every time.
Our small old CMM was decommissioned and both of our new CMM's are of a bigger size, throwing off his coordinates so his positioning's no longer work.
My question is, Could I add a manual alignment to the start of these old programs to snap the geometry into the location I desire? or would that actually make everything worse and I should look into other ways to convert these programs.
I know he has moved his programs from the old small machine to our newer machines but I am unable to ask him as he is no longer with the company.
I would say try it. Once software knows the location & orientation of parts it ought to adjust values in the DCC alignment portion. Make sure when manually probe the part to probe where DCC alignment is probing. Just go slow the 1sttime around.
As long as you can recreate the origin and orientation of the Part alignment you should be ok. Do this work on a COPY of the original program in case the gremlins sneak in.
