So I'm sure I'm doing something wrong here - 1988 Mori Seiki MV40 with a Fanuc 10M9B control. We just bought it secondhand and it didn't come with any manuals, so we're a bit in the dark here.

The machine is fired up, the spindle runs, everything looks like it should. I went into MDI and ran a T1M06 to try and set tools in the 20 place tool changer. As soon as I did, the error came up - 240 - EMPTY POT NOT FOUND. It forces me into an error screen and gives me the pages to either manually change the tool page, or run the ATC in manual mode (Pot up/down and arm forward/reverse). When I try to change a tool to 00 (there are no tools in the machine) nothing seems to change. When I try to move the tool changer by hand, I can move the pot up/down, but I can't seem to move the arm off of home position.

I've attached a couple of photos below - any advice is welcome! I'm coming from a 2004 HAAS and a Milltronics lathe, so I'm sure I'm either spoiled or just missing something obvious. Any help is appreciated!
