I have a vmc15 I bought from my work last year and it's only 3 axis. There are 3 more machines left to sell and one of them has a vh5c 4th on it.

The owner found out he can't get any more for the machine so he's willing to sell me the 4th for $500 with everything that goes with it.

I'm not an electronics guy and I've looked in the machine and it's hard to tell what parts are associated with the 4th.

Does anyone here have enough experience to tell me what I need to pull and not damage the machine I'm pulling it out of?

Thanks in advance.
