Otherwise capable coder/developer who just unpacked a TAZ 5.
I have printed three octopus. Adjusting the bed each time. Initially first layer adhesion was weak so I raised the bed and printed several bed calibration prints, tweaking each time.
Now I am printing a real object, but the support pillars are mush. I have sliced with slic3r. PLA, 3mm new roll, 190 Head, 60 bed.
