I am also having this issue. Earlier today I re leveled all the corners per this post: SOLVED: Taz 6 auto leveling is >0.5mm off (NOW PERFECT TO 0.01mm!)
And now I’m having the exact issue you described above. I’ve had the machine for 3 days and I’m absolutely disgusted with the lack of consistency and user friendliness. This isn’t my first rodeo 3D printing either, making this all the more frustrating. I hope someone has a fix
