I just switched printheads from a slice mosquito to a e3d revo. I doubt that could be the problem but thought I's mention it just in case. If I don't use a bed_mesh my printer (2.4) works fine, prints better now than with the mosquito. If I use a bed_mesh the print starts with the nozzle about as high as it is when the klicky switch hits the build plate during the bed mesh calibration. Any thoughts? I'd like to be able to use a bed mesh if I can.

Sounds like a misconfigured bed mesh , that's missing zero_reference_position
