This is primarily a sanity test, and I wish I knew what version I was on. Since upgrading, I can't enable hard limit switches because of EMI. I've done everything that was suggested in the troubleshooting docs. docs:blackbox-x32:faq-emi [OpenBuilds Documentation] Disabling it, I can use them to home. They trigger as expected, so I would like to try and roll back the x32 firmware to see if it resolves the issue. Figure it out from there, share my findings and we can poke through the change log and patches if it works. AFAIK, it was working fine before upgrading. If someone can point me to the previous firmware builds, that would be wonderful, thank you.
Yeah not firmware related no. Post Grbl Settings backup for review and pics of wiring, cable management, etc

You changed the Homing Debounce to a factor of 10 less than its default / what should be. Read the Grbl Wiki, and avoid changing advanced parameters without understanding their impact
That is an artifact when the limit switches wouldn't trigger, because I didn't have "$5=7 ; Invert limit pins, boolean/mask" set correctly. I fixed $26 value, everything yields the same result, 50ms, and 250ms can home if the hard limit switches are disabled just fine. When enabled, it still triggers immediately and I'm unable to home the machine still.
