Hi, I'm new to this list and English isn't my native language, though please appologise any mistakes in my writing. I managed to set up a four axis (x, y, u, v) configuration for a hot wire foam cutter for model plane styrofoam panels. The hardware is realised with stepper motors an the appropriate drivers. The drivers have the normal inputs (enabel, step, direction). It runs in the mean to my satisfaction. The problem I have is the integration of an external panic button (physical switch). The button is electricaly connected to the paralleport pin 10 through an optocoupler. The stepper drivers are enabled with pin 1 of the parallel port going high. What I want is to go pin 1 low when the external panic button is pressed and at the same time the "estop button" (toggled with F1) looking pressed and the "power button" (toggled with F2) looking unpressed/disabled on the Axis GUI. When the external panic button is reset, the "estop button" shold reflect the state and the "power button" should be enabled and pin 1 has to keep the state as before meaning pin 1 is still low. Pin 1 should go high when the "power button" is pressed again. Until now I din't manage to realise this behavior, but I think it isn't unkommon and somebody in the community has realised it already. Any hint or solution is highly welcome.
