Bed temperature for first layer

Hi!

When I generate a gcode file, it appears as if the bed temperature setting for the first layer just isn't used. For example, in the ABS filament preset, I set first layer temperature to 110, the rest to 100. When looking at the gcode, there is a "M140 S100" command between layers 1 and 2 to set the bed temperature to the "other layers" temp, and "M140 S0" at the end to turn off the bed heater (which I have in the "custom end g-code"). There is nothing that turns on the heat before layer 1, and the "110" number just isn't mentioned. I either need to set the bed temperature manually before printing (which I forget to do half the time), or have it in the "custom start g-code" (which means I have to change both "Filament settings" and "Printer settings" for different plastics/temperatures).

It simply seems the Filament Settings -> Filament -> Temperature / Bed / First layer setting has absolutely no effect on the output gcode (other than the "; first_layer_bed_temperature = 110" comment I see when doing verbose output). Is this intended behaviour, a bug, or am I just doing something wrong?

Using Slic3r 1.0.0 on Mac.

Try this in start G-code:

M104 S[first_layer_temperature] ; set extruder temp
M190 S[first_layer_bed_temperature] ; set bed temp & wait
M109 S[first_layer_temperature] ; wait for extruder temp

Also read the tooltip for start G-code - if slicer detects M104 or M190, it does not generate any default temperature setting G-code.

I had an M140 command (not mentioned in the tooltip stuff, it just says M104/190) in the custom G-code that was commented out, which was apparently enough for it to be "detected" and ignored. However, using variable names in the custom start G-code is a lot more elegant. Also it means I can do an M140 to start heating, go homing while it heats, and then an M119 later to wait for all temperatures before starting to print.
