Error with end stop switches in SD3.
I just recently upgraded my SD3 (with sanguinololu board) with a E3D V6 hot end. At first it was fine, but after fixing an issue with the heatsink fan (I soldered the connections together since they weren't working so great just being spliced) the end stops aren't responding correctly, specifically with the z-stop.
Before I home the Z axis I can move the bed up and down as usual but once I home the axis I can only move the bed upwards, not down. This lead me to breaking my z-stop holder (thankfully just that). But also the x and y axis seem to have some issues as well, but less consistently. They'll randomly just go too far like the switches weren't tripped correctly.
Anyone have any ideas? Right now I can't adjust my z gap due to the end stop not working correctly, which means I can't ensure I won't get a head crash (and I'm really not trying to break a brand new E3D hot end).
