Version 2.1 BSL UV Cloudray UV 5 PRO

Hello! I have a BSL board in my Cloudray UV-5-PRO. With version 2.1 RC 11, I was able to control the Z-axis motor. With the final version 2.1, the control menu has disappeared. Am I doing something wrong, or did the control feature not make it into the final version?

I think I just read that it was just not reliable enough for production, but they are still working on it.

I hope it will be released soon. It worked well for me in RC 11, and I will continue to use RC 11 for my UV laser.
