Dual Extruder Set Up Issues

I'm trying to run two orbiter extruders inline with Belay to prevent filament feeding issues on my 500mm VC4. The second extruder pulling off the spool does not move at all and I cannot find what I did wrong (the extruder does work when plugged into the toolhead, so it's not a mechanical failure). I'm using the following config, and after several hours of searching cannot figure out what I did wrong. I've tried using the SYNC_EXTRUDER_MOTION EXTRUDER=my_extra_extruder MOTION_QUEUE=extruder but only ever get the error The value 'my_extra_extruder' is not valid for EXTRUDER Please help, I've spent hours on this and I know it shouldn't be that hard to get working

I'm off in bed, but am curious about this problem. Does belay have install directions?

Dead stepper motor driver 🙃 It was a brand new one, so didn't think to swap it out until this morning So the above config is golden
