OKUMA LU-15 B Turret problem

[CNC_Tools]

Hi guys, long time no post

I'm getting to know my LU-15 w/ OSP7000L on it.

I'm trying to run a live center in the B turret and turn with the A turret. Got, that far, but when I G14 back to the bottom turret to pull away from the part it gives me a variable limit error. I'm doing a G14 then a G0 X20 Z20. The soft limits are set plenty large for the tool. I think it's dropping the the tool offest T070707. My local Okuma dealer is next to useless,

Please help!!!!!

I use the below 2 sub programs for B turret centre use

You will need to create a program variable CNTR, Also the values are Metric

OCNTR
(USE CENTRE ON B TURRET)
(CNTR = Z DEPTH)
G140
G00 Z=CNTR+150
G0 X0 Z=CNTR+50 T012012
G0 Z=CNTR+20
G94 G01 Z=CNTR+5 F3000.0
G29 PZ=11+LOAD+10 (11 IS THE TURRET Z LOAD TO MOVE)
G94 G22 Z=CNTR D0.5 L0.5 F300 PZ=11+LOAD
G29 PZ=11+LOAD-5
G04 F0.5
G28
RTS

OBHM1
(B TURRET HOME AFTER USED AS CENTRE)
G140
G94
T012012
G1 X0 Z=CNTR+20 F3000
G00 Z150
X800
T010000
V30=VTOFZ[1]
V31=[VNVLZ-VZOFZ]
V31=V31+0.5-V30
G00 X1000 Z=V31
G95
RTS
