Realigned the rails. I’m happy with this.
Wow. How many places did you probe?
4 point, out towards the corners.
80 point. Slight hill across the center. Still less than my normal layer height.
I wouldn’t be surprised if my Y rail is slightly bent from crashing the hot end into the bed.
That is still very good. What program are you using for visualization? Duet, probably?
I have been learning about this whole ubl business and I am liking what I am seeing. I don’t like probing it 25 times each print (or 80), but if I can just probe it occasionally, or for different temperatures and then just recall it, I can hopefully get that last 0.05mm of even first layer, without having to wait 20 minutes to start printing.
