Help with rotary y axis accessory

I just hooked up a new YRR rotary accessory for my Ortur LP2. It seems to be hooked up and operating but I am having an issue getting to home to 0,0. When I reset and start up the position says -600, -600. Any advice on how to get this back to 0,0?

I am not a professional, but had a similar situation with my Atomstack laser. Basically shut down the laser and lightburn. Manually move the laser to 0,0. Then turn back on. At that point it should reference 0,0. Hopefully that works for you.
