How's that for a report? Where I am is that I've wired the N/O lead from the switches to a piece of protoboard that corrosponds to pin d9 and ground on the arduino. I then sandwiched the board between the socket on the L7 and the arduino. I set up GRBL, compiled, and uploaded it to the card, configured soft limits and homing, and... ... ... nothing. Wouldn't even recognize the switches. Sending $h resulted in a whole lotta ?$g with no other responses.
So I disassembled the pieces and re-soldered them. This time I uploaded Zax's grbl11f_z-xy hex. And... well something happens. I send $h, hear a click, and then arduino tosses a GRBL error suggesting that I check the pull-off. There's no movement though. I tried adjusting $27 from 1 to 10 and then 100 but there's no change. I double checked my pins. I wonder if it's a setting or if my soldering in bad.
Right now I have set:
