Hi!
I am new in Okuma. Recently I have got 2 LC20 with double turret and OSP5000-G. I tried to change tools and in one sample of program found how to do it.
M65 and M66 command did it. But I did not find any description in my manuals about this commands. Can anybody help me to explane what this commands do?

M66 is dangerous - turret rotation (tool indexing) is allowed not waiting nor turret stop, nor axis limit signal.
You can change the tool while turret is sitting on Z and X user defined limits normally

[fordav11]

M65/M66 is an option to allow you to index the turret
anywhere (even if a crash would occur when indexing).
You don't really need it.

You can index tools easily. Just move turret to maximum X or Z
and then issue tool command. i.e.....

G00 X20.0
T0101

OK, hence please tell me how can I change tool in program?
The first I need to let axis pass to limit. And only after that I can change the tool.
Can you give me the peace of code to do it?
May the first command will be like this G28X..Z.. (go to tool change place)
Then some like M6T2
And the the procgam continuing G0X..Z..
Is it right?

I already gave you the code
M6 is for a mill. not required on a lathe.
Okuma is not Fanuc. It doesn't use G28

You just rapid to any large number. the machine will travel to it's physical limit.
then T then tool number

that's all

i.e....
$TEST.MIN%
G13
G140
G0 X20.0
T0101
G96 S200 M3 G110
G00 X... Z.... M8
(the rest of the program here)
G0 X20.0 Z10.0 M9
T0100 M5
M30
%

Thank you
I'll go check it on Monday

Your code works. The problem was in G1 command.
I wrote:
G1X300F200 and the message alarm about increase max X value appears.
If i write something like
G0X300
T0202
....
then it works.

On every machine G1 requires feederate, or last defined feederate will work. sure, error occurs in case, when feed per revolution is active and spindle is stopped. G0 is rapid traverse, no need to define feederate by command and no need of spindle rotation

[fordav11]

on Okuma in G1 I think it will check X or Z end point to make sure it is inside the limits.
in G0 there is no checking.
