It seems to work, holy wowzers! I just compiled a dual endstop build with no pin edits!!! I have to test this ASAP.
For those unsure of the excitement, this means all 5 driver boards can now do dual endstops by editing only two lines in config advanced. We used to have to go in and fudge the pins files for each individual board! Easy Peazy!
More exclamation points!!!
