@dc42 I noticed some other strange thing, which is maybe related: my start.g and bed.g turn the heaters off via
M568 P0 S0 R0 A0 ; turn tool 0 off
M568 P1 S0 R0 A0 ; turn tool 1 off
M568 P2 S0 R0 A0 ; turn tool 2 off
and the beginning. No other temperature related settings. When starting the print on 3.4.6 I see
then
while true meshbed leveling: This happens in 3.5.0-rc3+4 as well. On 3.5.0-rc3+4 even after the print I can see
. My stop.g contains the lines
M568 P0 S0 R0 A0 ; turn tool 0 off
M568 P1 S0 R0 A0 ; turn tool 1 off
M568 P2 S0 R0 A0 ; turn tool 2 off
as well.
