Hmm. A lot of questions with your profile. First of all, you aren't using the firmware overrides, so I have no idea what firmware settings you have. It is also possible you have the wrong firmware configuration because you aren't using it. So I would suggest enabling that option on the G-Code tab. For now, I will assume you are using stock RepRap firmware configuration (but you should verify that too, cause if you have that wrong, that would explain why it isn't heating)
When I slice a model using your FFF profile and the RepRap firmware configuration, here's the first few lines of the file that I see.
Code: Select all
M104 S190 T0
M109 S190 T0
G28 ; home all axes
That clearly has the M104 command to set the extruder temperature and then the M109 command which will wait for 190C to be reached before continuing the build. So I see nothing wrong with that (of course, it assumes you see those same exact lines in the start of your gcode file)
