This might be close to another topic.
I am using the software for dual end stop, and noted the menu had spindle and laser controls.
I have a dual relay wired and control the spindle from the relay.
I also ran a wire for my laser, and can remove the router and put a laser in its stead, then use the laser control.
I want to add a menu button for the vacuum, and also turn it on from, the menu, any idea how to do that?
I have 4 conductors going to the relay box, +5, Ground, and two relay signal leads. The relay has optical isolated inputs.
Config.h (already) had #define SPINDLE_LASER_ENABLE_PIN PC9, and I use that for the spindle relay.
(minor change to invert the signal but it works)
Not sure how to proceed, maybe using PF9, but how to add a menu for the vacuum
