implement 8-tool turret on lathe

I am trying to use 40 digital inputs with classicladder. they are created in the .ini configuration. but I can't see the symbols. I can only see 20. I'm using 2.7.14 I'm programming the turret. Why does this happen?. in the custom.clp file they are not listed either.

I have already created the panel connected all the signals, but I can not do the logic, I do not see the 19-39 in pins

I also had this problem, I solved it by editing by including the entries inside the custom.clp file.
Ex.:
%I20, %I20
%I21, %I21
….

A question, how did you make the list of tools on the screen? I use Gmoccapy do you know how to do this?

TURRET WORKING      

I leave here the turret working !!. Although it could improve the programming, it was a challenge for me to do it and I will surely do so in the future. Just thanks to everyone who always helps me in this forum, Thanks Linuxcnc for being a great application that allows me to do these things !!! I will continue now with other challenges !!! thanks to all

use panel programming PyVCP

I have a new problem !!!

I had not tested the turret within a program, I assumed that while the change did not finish, the program would be stopped.

and it happens that the program continues its execution while I am in the middle of a tool change.

How can I pause the execution until the change is finished?

thanks!!!!
