That should work, thanks.

Right, that makes sense. Is there a way to quickly disable the stepper motors, without killing power. I know I would not have position feedback anymore and the machine would lose its home position but that would still be useful to me.

I have an acorn board running a diy cnc lathe build. It using some Chinese nema 34 closed loop stepper motors. What I like to be able to do is run the axises manually with a hand wheel while still getting position feedback to the controller. So my question is, is this even possible? How do I disable ...

Thank you for your help guys! I found a tiny piece of what looks wire shielding foil jammed under the input terminal block and touch the ground under the mounting screws. Lights are all on now, I’ll finish testing the inputs this evening.

I haven’t changed anything from how I received it.

I completely remove the acorn board and only have the power supply connected. I get 24v when not connected to the input 24v in and 0v when it is connected.

I also removed all stepper motor wiring aswell disconnected from the computer. As soon as the 24v in is feed to the input terminal. Voltage goes to 0v

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 ...
