CR-10 Ignoring Z-Stop Switch, Keeps Trying to Lower I have a CR-10 with TH3D's most recent firmware on it and an EZABL (Plug &amp; Print Auto Bed Leveling Kit) installed.  My problem is that when I select "Auto Home", the printer ignores the Z-stop switch and keeps trying to lower the extruder, grinding and shuddering until I have to power it off.  I can't seem to figure out what the problem is.
I had this same issue with my CR-10s. My black and white wires were reversed where I plugged them in to the motherboard in place of the stock z stop wires. I had to take apart the connector and swap them, as they came backwards from the mfg. Once I did that it worked perfectly.

The image I'm attaching helped me solve my issue. It is not mine, after much searching I found kenneycp's reply on this comment thread
