Hi all,

I've been trying to get my Okuma Howa Millac 3VA working after sitting idle for some time. Everything seemed to be going well until I tried to do tool changes.

The first problem: I can't get any toolchange related commands to work in MDI mode except for toolpot vertical and horizontal and the interlock bypass commands. Trying to move the arm with M80-81 doesn't work. The control simply hangs up and doesn't respond to cycle start.

The second: I can't even get the tool magazine to set numbers or index the tools using the panel on the side of the machine.

Before this happened I lost all my parameters and programs and had to reset them. The batteries failed after sitting in storage for a while. The toolchanger worked back then, although I'm not sure if the two are related.

I'm at a loss here. Can anyone help me muddle through this?

Thanks,
Will
