The Grbl $5 is a boolean value and on the Lead 1010 Blackbox X32 the value is set to 7. Is Grbl $5 true for any non-zero value or is it false for any non-one value? Also the Grbl docs says "If you invert your limit pins, you will need an external pull-down resistor wired in to all of the limit pins to prevent overloading the pins with current and frying them." If the value of $5 is 7 indicating an inverted limit pin does that mean the X32 already has the pull-down resistor otherwise what size resistor is needed?
Thank you, I was wondering if $5 was really a bitmap mask of true/false (1/0) values representing each of the 3 axes.
