So many issues on my FarmBot

Hi every one.
i,m facing so many issues on my FarmBot Genesis 1.4

1 - I can’t schedule any sequence, i tried every sequence i have and it’s just don’t trigger. I’ve tried every FBOS avalible ( Beta, Alpha, Stable).

2 - When executing an action i can’t close my browser, when i close FarmBot stops. For example: if I set Photo Grid to run and I close my browser it stops taking pictures and only comes back when I open it again

3 - Z stepper motor is so loud at the default speed, and i can’t change it without a custom firmware.
Why do I have the option to change the speed in the web app if it doesn’t work?

I’m trying so hard to get FarmBot to work, but I’m losing hope.
