it just fails saying axis length error...i managed to sort it kind of...what i found is if i autohome the run self test it passes fine...its only  when i start off the selftest with extruder say in middle of x it fails..

I have the same issue. The printer prints just fine with 3.8.0, but after i changed the einsy case I thought I would do a self test. After the fan test it does not seem to try a x-axis test, the z-axis is raised and then it immediately says failed axis length, axis x 
but the printer just prints fine after I skipped the self test and calibrated the axis.
