Dioed

[john e kline]

While carving I found a plastic square "U" shaped black dioed on the board being carved. There appears to be two diodes installed. The machine seams to be working fine. Does anyone know what this is? Could this just be a piece that was left behind during manufacturing?

Sounds like the home sensor which is mounted to the Z-truck (see user manual for a good picture). This sensor is no longer used as of firmware 1.119, so no worries.
