Isn’t it fantastic when you set the filament change code on the wrong layer? I set it on the layer before the 17, which is the layer before the QR code starts, which is Layer 18. But the filament code gets inserted BEFORE that layer number. So, it was inserted before layer 17 and when I realized, it was too late. Half of the plate went black. Damn it. 3hrs wasted… re-slice, re-uplaod, restart…
