I am just moving from Mach3 to mach4, and I would like to use my wired pendant.
The problem is that under mach3, a "Brain" file was used, and not applicable to mach4.

Lua is the obvious answer, and should not be too difficult, once a start is made.
Ideally, it could go in a "Lua Panel" on the screen, I hope to avoid changing anything in the Standard Lua file (Screenscript.lua)
Anyone fixed a similar problem ?

Use the PMC ladder logic feature of Mach4.  It is very similar to Brains.

Steve. Thanks for that, hadn't found PMC yet. Now I have + a good video on it as well.
