No response from A axis

#1

Machine: DIY 50W CO2 laser using lightburn

Board: Cohesion3D laserboard

Firmware: Smoothie Cluster

Problem/ Question: I can not seem to get the A axis to do anything. I am using an external TB6600 driver for all the axis, the X,Y, and Z axis work fine. But I don’t get any response from the A axis.
Is this a Smoothie configuration issue? Any help would be appreciated.

Thanks

Hi Richard, can you please post pics of your board and the wiring?

Also, have you made any changes to the stock config file?
