Rotary Setup Issues

So I recently upgraded to a mini gerbil controller board from Awesome.Tech. I also recently purchased a V2 Rotary from Holgamods. I’m using Lightburn. While I know that the mini gerbil has no direct rotary support, I thought for sure I could just replace the y-axis on the board with the rotary connection. I can get the rotary to home, but whenever I try to engrave or jog the laser head, I get an error:9. Anyone been able to get this work?

If I need to provide more details, I can. TIA.

Alarm 9 - Homing failed - grbl alarm messages

Maybe the folks at AwesomeTech have suggestions.
