Need Help! Tool and ZeroPoint setting on Fanuc 18i-TB

Hi.


We have a Lathe (Alex-Tech Viper 3000 YMS) With the Fanuc 18i-TB controll.

I have problems With setting the tool data for double tool holders.

For the T0800 holder I use T0808 and T0818 for the tool I use in the sub spindle.

But when I am going to set the Zeropoint on the part that is in the sub spindle I can not manually get the T0818 tool to show on the screen.

When I punch in T0818 in MDI I have too reset the machine to get back in manal "JOG" mode, and then the tool data on the screen goes from T0818 to T0800. So therefor I can not set the Zeropoint With the T0818 tool.

Any tips or ideas?

I use G54 in the main spindle and G55 in the sub spindle.

Tha program is a part transfer type, from one spindle to another between operations.
