Calibration is an issue right now for many users. Bar is actively working on improving the process and getting it dialed in but it’s complex to say the least.
It’s also important that whatever device you are using to connect to the Maslow does not lose connectivity or go to sleep, otherwise you lose access to any feedback the machine is trying to send. I would recommend trying to connect with something you can keep in the room with the Maslow while it’s running. It’s probably not a good idea to leave the Maslow unattended while it’s running anyway. Things can go wrong quickly.
In terms of the firmware, if you’re trying to run a version that hasn’t had an actual release yet, it will most likely not show the correct version in the UI. There was a similar thread from earlier today: Double check Maslow version number
