yes, I tried to raise the screw to level up and down, but it seems not working in this way, also, you know before the actural printing, the two nozzles are active the level, the BB nozzle should be locked and raised up, but it did not. I dont know why, by the way, I updated new fireware.

currently, I am using UT 3, the nozzle does not print the same thickness on the build plate in one go. front side thicker skirt and rear side thinner skirt, what is wrong with that, does anyone know that? Thanks
