tool prepare

in m y lathe machine with turret
i am using "io control tool prepare "signal
to unclamp my turret and rotate
after position arrive i clamp turret and send signal io control tool prepared to linuxcnc

not if i am using in auto program and i call two tool in one program

when one toll arrive .....
second tool prepare command automatic shown in plc ....
and tool change again even if program not reach at next tool
(this like linuxcnc look ahead ion auto program)

how i can disable look ahead function in linuxcnc

when i call tool number only that i i want to see io control tool prepare signal from linuxcnc

can any one make comment for this issue

(i want to disable next tool pocket number and prepare signal automatic shown in linuxcnc)

i want only tool prepare signal when exact line number come to execute

Link your hal file and ini file

Thank you
But Which file and how to link ?

Tool prepare works correct, the question is how you did connect tool-change and tool-changed in Hal, if the loop is closed by default you will get the described behavior.

Norbert

All files in your config folder that end in
.hal
.ini

Below the text box is an icon with a paperclip that says "attachments"

tool-prepare is the wrong signal to use.
tool-change is the right signal for a lathe toolchanger.
tool-prepare and tool-prepared should be connected together so the prepare sequence is ignored.

You are right ...I also feel that tool prepare is not suitable for turret
But when I use tool change

I need enter every time TX M6
For machining Center is ok
But for lathe general theory is to use TX only to call tool on lathe turret tool

Is there any way we can use M6 in Plc only no need to call M6 in program

And use tool change function

Please guide

I already link Hal file to ini file

And all signal I can use in Plc

Like
Tool prepare
Tool prepared
Tool change
Tool changed

Thanks

I connect tool prepare directly to prepared

And with Change he signal
I unclamp turret
After confirmation unclamp

I rotate tool disk

Then at match number position

I stop Fisk and clamp turret

But some time turret miss behave

.....
I want to know

Tool prepare signal always pop up
If I use auto program and call two tool in one ore gram

When first tool changed and program running for cutting task

Same time that second tool which prepare signal again pop up

And this is point I am confuse

I only want

When I call tool only that time tool prepare signal show me
In auto program with two tool used

You need to remap the toolchanfe codes.
Look at the AXIS simulation config...fanucy...it uses remap to change tool with only t code.
