Start G-code Omitted from Sliced G-code 2.8.0
In the attached PrusaSlicer 2.8.0 project I've replaced the M104 and M109 lines of the default MK3S printer Start G-code as follows:
M104 S{first_layer_temperature[0] - 50} ; set extruder temp minus 50 to avoid stringing during calibration
M109 S{first_layer_temperature[0] - 50} ; wait for extruder temp
That works well, as I see the reduced temperature in the resulting G-code after slicing. What doesn't work though is adding additional M104 and M109 commands after the "G1 Y-3" line, like so:
G1 Y-3 F1000 ; go outside print area M104 S[first_layer_temperature] ; set extruder temp M109 S[first_layer_temperature] ; wait for extruder temp G92 E0
The resulting G-code is missing the second M104 an M109 commands. This issue happens with any commands, not just temperature. What's interesting is Compare Presets shows only the first M104 and M109 commands as different.

Turns out I was putting the second temperature commands after the first G1 Y-3 command, which is inside an if-statement 🙃
