It should be waiting on that line in the toolchange macro. You may need a T-1 (unmount all tools) in the startup.
As i have it now, I deleted the temp gcode in the start gcode, and now it generates it for the proper tool automatically, however, it places it before the start gcode. Inputting a T-1 in the prusaslicer start .gcode prompts an error message saying something about trying to extrude with no tool selected.
-
Yeah, sorry, I wasn't clear. May need a T-1 and a later T0...
-
@Danal the problem with putting in any "T" command in the start gcode is i have to modify it every time i want to change which tool i want to use, which is what i'm trying to avoid

The generated G-code from any slicer that is aware of two or more tools should contain a mount command for the tool it is going to use.
The T0 at the end of config.g is really there for slicers that are not multi tool aware, and that therefore do not have any T commands (to your point about not changing things per job...)
Hmmm... what is a "eat our cake and have it too" for this? Let me ponder a little.
-
@Danal wait are you referring to a t-1 in the start gcode of the slicer, or in the config file?
-
In the config file. Or just don't have a T0.
-
@Danal Gotchaaaaa. i assumed you meant the start gcode. Ill remove it and add a t-1

adding an M109 S[first_layer_temperature] cause it to heat up the wrong extruder
M109 can't work without a tool being selected, so if no tool is selected then it selects the first available tool. So if you want to apply it to tool 1 instead of tool 0, you need to add the T1 parameter to the M109 command, or put a T1 command before the M109 command, or select T1 manually before you print the file.

@dc42 I understand that, and its what im trying to avoid. I dont want to have to change my start file every time i want to change the extruder, but i think i got it thanks to Danal.

In that case, make sure there are no T commands anywhere in the GCode file. If you send T1 before you print it, it will use tool 1. Otherwise it will select tool 0 when it reaches the M109 command.
