I apologize for starting another thread, but I try to solve the problems one at a time.
The problem with the tool change is 90% solved, so I thought it was ok to open another thread with the second and largest problem.
I apologize again for the inconvenience created.
I was wondering if it would work by opening two mach4 screens, each with its own code and different control boards.
I know it is "impossible" at the moment, but it was an idea.
Citizen has dual control, but in fact it is a single PC, it has one board on which it's also the PC and the NC .
A single code is created which will be later divided into separate windows by $ 1 and $ 2.
