The bed temp issue is also elsewhere on this forum: Luban sets Bed Temp to 0?
But the problem gets weirder. Today, I tried again and now the bed temp is 65. My adhesion problem has also gone away, seemingly on its own.
Snapmaker is unclear as to whether to use the breakaway PLA in the right extruder or to just use a contrasting color. Yesterday when I first encountered the problem, I was using ordinary PLA. Today I tried with the breakaway, but still had adhesion issues, although significantly less than yesterday. Then I decided to try ordinary PLA in the right extruder and now I don’t have any significant adhesion problems at all.
