My printer refuses to lift the plate during a print for reasons unknown . The manual raise controls work and the printer self check shows no issues but the prints are all flat . The only other issue that helps with the diagnosis is that when homing(pressing the manual button) the build plate gets to the top and it will keep going up without stopping causing a clicking noise as it keeps trying to to go past the top limit . My initial thoughts are a z axis sensor fail but what do you all think ?
