Here's last night's part. The printer was feeling a bit artistic and decided to print a stylized C with frilly fringes instead of a height gauge. MP4 PLA, standard temp 190, raft @ 5mm, slowed the first layer to 5mm/sec for adhesion and the second to 10mm/sec, 100mm x 100mm x 3mm, OctoPrint startup GCODE tweak to slightly extrude after the priming line Since I'm about to change to the new bed, I was hoping for a "before" part to confirm an idea that the old bed has a diagonal bulge in the back/right direction. I'd then print an "after" on the new bed and then do the firmware upgrade and repeat. If you watch the corners, they begin to curl up in earnest which then sets up for the drama/comedy in Act III.
