If so, just wanted to briefly compare notes. Mine prints went from very dialed in on the engineering build plate to trash when I first received my Wam Bam Carbon Fiber build plate. I posted photos of the problem on a necro thread (Fine tune the z-height during printing on BambuLab X1C? - #6 by NeverDie) with a different title but got zero replies, so I’m going to start-over with my own thread and the right title this time. I think I’ve diagnosed the problem to being caused by the Micro Lidar, because now that I’ve disabled it, it seems to work.
As final confirmation, I just know whether anyone else using the Wam Bam CF build plate has reached the same conclusion?
