Trying to level sovol 1 getting errors

Trying to level the bed on my sovol 1. I select auto home, the extruder goes to the center of the bed. The bltouch deploys twice and get the below error codes on the LCD. The extruder sounds like a jack hammer moving slightly up and down in a jerky fashion.

Homing failed, printer halted. Please reset.

Any help greatly appreciated
