Re: Bltouch Offset value
Hello, maybe the knob is too sensitive, you can rotate it slowly. Or you can connect to a computer and adjust the offset value on the slicing software.

Re: Bltouch Offset value
It's an issue with the firmware. Just use the closest number you can get to. If you want to be precise you can change it via G-code M851, or use the EEPROM Marlin Plugin on Octoprint for an easy web-based edit.
