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 .....

and tool change again even if program not reach at next tool
(this like linuxcnc look ahead ion auto program)

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.

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.
