Automatic Bed Leveling with Conditional Gcode Iterations

@fcwilt All makes sense. I guess it just goes back to cats, preference to work-flow, and ingrained habit.

During the day's events, I thought of the above conversations and formulated and blend of both ways (dwc/slicer stop/stop gcodes) to handle filament specific settings. I just made the following setups - all is working very well. It is very basic/generic but will grow from here.
Let me know any thoughts./sys/start.g:

Hi,
Just FYI you don't need both M140 and M190.
They both set the temp and activate the heater.
The difference is that M140 doesn't wait for the temp to be reached whereas M190 does.
The same applies to M104 and M109.
There is also M116. From the docs, M116 by itself it does:
waits for all temperatures and other slowly-changing variables to arrive at their set values.

For some reason, it feels a bit to foreign to me to offload stuff from the slicer's start and end code spots.
When you use multiple slicers it makes it a lot easier to manage.

Thanks @fcwilt! I didn't know I was messing that up. I re-read the gcode documentation on this, I believe the following would be the most efficient.
M104 S[first_layer_temperature] ; set extruder temp M140 S[first_layer_bed_temperature] ; set bed temp M116 ; waits for all temperatures -

Now what I and others do is start the heating and then do other things that don't need to wait on the temps, like homing.
When all of the "other" things are done then you can use the M116 to wait before proceeding to the next steps.
It can save a bit of time.

Thanks much! Made changes to above post.

With all sorted discussed above, I have no actual contents in the following files: tfree0.g, tpost.g, tpre0.g
Can I delete these files from the sdcard or will this throw an error?

When in doubt you can always rename them while you use your printer to see if an error occurs. Then you can undo the rename if it turns out you need them.
When I do that sort of thing I add .HIDE to the end of the name so tfree.g becomes tgree.g.HIDE
Now I don't think you need these files - I think that are used when changing from one tool to another.
I've never had a printer with more than one tool so I've never had these files.
