Need help..just got my ft5 powered up, added this mod and Dustins firmware form the start. The problem is that z will home and hit switches, they both lite up red. then z will continue in the up direction unless I hit the power button to stop it. Destroyed z2 endstop already. Testing with m119 per blog instructions shows all ok at the end stop end of things.,,, as side note I have not set origins or offsets or any thing else other than uploading the firmware..and sending it to home. I must be missing something.. uuuughh! PS: coming from delta printer so things are a lot different than I'm used to.
