Negative bed temperature?

[GunSmoker]

I have a weird issue with generated g-code from Simplify3D (4.1.2). For some reason, S3D sets bed temperature = -1 for first layer, even though it is set to 70 in settings.

Changes in bed temp for other layers are OK. A similar, but different profile works OK.

Resulting g-code:

Code: Select all

M140 S-1 ; set temp for bed do not wait
M190 S-1 ; wait for bed to reach temp
M104 S215 T0 ; set temp for extruder 0 do not wait
M109 S215 T0 ; wait for extruder 0 to reach temp

I can't see what is wrong with my settings. Any ideas?

For some reason bed's temp controller was set to T1 instead of T0. May be I have used scroll wheel or something...
