For your Y axis drive, try wiring J3 pin 4 to Acorn DB25 pin 5 and J3 pin 3 to Acorn DB25 pin 4.


Moving J3 pins 3 and 4 over to the DB25 connector has it jogging now. I left the configuration in the CNC12 wizard set as it was with motor configured with screw connections. Still using ...

Did you set the drives to have the inputs pull up?
Yes, screenshot attached.

Disconnect the drive from the Acorn and verify that you see 5V across the inputs to the power supply ground.
Not clear what you want me to check here.

Is "Signal Ground" from drive J3 pin 10, 12 ...

Did a little playing today. Attached a screenshot of CME I/O monitoring screen that shows pin states. As expected Pin 5 changes state when jogging opposite directions in CNC12 software. Currently negative direction causes it to go low in drive.

I hooked my oscilloscope (Snap-On ...

I found one of my mistakes. I needed to invert my lube pump signal. Acorn saw it as a fault. Now have voltage on direction signal that changes state when using positive and negative directions. Also numbers on Y-axis move now. But still no movement on the motor itself. I'm thinking I have some ...

There is no E-Stop on the system currently. No voltage present on the direction pin when I try to jog the motor either direction. Report attached.

So I finally got the panel re-built, and everything powered up. Decided to work on the Y-Axis first. After I saved the original configuration pulled from the drive, I configured that drive per centroid467's recommendations and connected J3 pins 3 {IN6},4 {IN5}, and 5 {IN2} from the drive side to ...

Was reading through the CME User guide this morning. Looks like I can configure the I/O ports with multiple options (starts on page 52). Not clear to me what options to use. Attaching manual.

Have a cable on the way. Will try and connect an post some screen shots later this week.

I Have the same drives on an old Bridgeport I am starting to retrofit. Bought an Acorn over the weekend to replace the old motion controls from CNC Pro.

Old system jogged around fine, but not sure where I need to land the wires onto the Acorn when I receive it. I have attached a map of the pins ...

Thank you for the insight and direction. I'm looking forward to getting this project running with updated control system.
