I have a question that hopefully someone here can answer.. We have a UMC-500 that came with the remote jog handle. I haven't unclipped it from the holder in the 2 years we have run the machine.. We also have a new VF-4 that was bought as a special because it was ordered by another customer and cancelled.. This did not come with the remote jog handle option and I sure wish it did. Haas wants almost 2K to add it... Can I swap out the unit from our UMC to the VF4 relatively easily or are there some hardware/software changes that need to happen? Thanks in advance.
