No it’s connected to the 24v positive(black wire closest to the yellow in pic). It also reads 24v on the multimeter. It goes to 0v when plugged into the 24v in. On the input terminal.

Sorry attached wrong photo, this one shows the 24v line attached

To rule out all wiring all I have connected is step and direction wires for each axis. These work fine. I have power coming into the power terminal of the acorn using the supplied power supply and wiring harness. When powered on I read 24v at the power terminal. When I connect the single black wire ...

The problem happens when I feed the 24volt to the 24V in on the input terminal. As soon as I attach the 24volts all lights tu...
