Automatic Bed Leveling with Conditional Gcode Iterations

Then it passes off to the slicer for setting the temps for the print.
As you may have noticed in my print_begin.g macro I rely on the filament feature to set bed/filament temps.
I do wait for the temps to be reached before starting to print. I don't know what a "prime line" is - I just print a 2 line skirt so I can watch to see how the first layer is going down and adjust baby-stepping or abort, as needed.

@Phaedrux Thanks for sharing. Do you use filament/config.g or just use slicer start code?

I haven't used the filaments function for a long time. I use prusa slicer and cura interchangeably. I use prusa slicer for the filaments library and refer to it when I'm setting up a print in Cura.

@Phaedrux As of thus far, me too. For some reason, it feels a bit to foreign to me to offload stuff from the slicer's start and end code spots. I do plan to slowly start migrating stuff over but only after I have everything else on point.
-
@Phaedrux For prime line I made a crude random(ish) number generator to not get a 'prime line gutter' on my plates. It gives a numeric swing of 9 to -9.
floor(10*(cos(sqrt(sensors.analog[0].lastReading * state.upTime))))So for the prime line, it would be (using Y as an example / with a .1mm randomness, targeted at -2):
Before: G1 X0 Z0.6 Y-3.0 F3000.0; After: G1 X0 Z0.6 Y{-2+(0.1*(floor(10*(cos(sqrt(sensors.analog[0].lastReading * state.upTime))))))} F3000.0;So my use is to have the M98 P"0:/sys/PrimeLine.g" called after temps are set and obtained by the slicer's gcode.
;M98 P"0:/sys/PrimeLine.g" ;This sets up the prime to be initiated at a 'randomized' Y positon from -1.1 to -2.9 G1 X0 Z0.6 Y{-2+(0.1*(floor(10*(cos(sqrt(sensors.analog[0].lastReading * state.upTime))))))} F3000.0; G92 E0.0 G1 Z0.2 X100.0 E30.0 F1000.0 ; prime line G92 E0.0 -

My goal was to have as little filament related items (like temps) in the slicer since I hoped to avoid going back to the slicer to generate a new gcode file just to change a temp.
So far that approach is working for me.
YMMV.
Good luck.

@fcwilt That is my eventual goal also, but because from within the slicer - I use inner-slicer variables, that portion would get somewhat lost?
I'm slowly brain-storming different ways to skin-the-cat, but as of this moment, it feels like I happen to be dealing with skinning Schrödinger's cat. -

I have not found that to be a problem - yet. What variables do you use?

Hard to skin a cat that won't stay in one place.

@fcwilt said in Automatic Bed Leveling with Conditional Gcode Iterations:
What variables do you use
Mostly the temps for hotend and bed.
While I do use the filament option in duet/dwc to get me to the overall-generic temp for the chosen/loaded filament type, I still use the slicer to vary the temps for each different brand/batch of the filament within the choose type range. I'll most likely use the start.g script to do most of the setup and prime line, then the slicer start-gcode could bring the temps to the exact settings, and then start printing. This would simplify switch between slicers and give a one-stop-shop to adjust the starting sequence as needed.Cheers,
Kolbi -
Thanks for the info.
I make an filament entry in the DWC for each filament brand/kind/color that I find needs different settings. Currently the settings that I control in the config file for each filament are the temps and the extrusion multiplier.
My goal was to allow using different slicers with as little duplication as possible by moving what I can to the Duet.
In the three slicers I use they each call two macros "print_begin.g" and "print_end.g"
I tried using start.g but it is called before the slicers set temps whereas the locations in the slicer to call "print_begin.g" happen just before the gcode that actually prints the object. So my filament config files get to override any slicer temp settings.

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

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.

When you use multiple slicers it makes it a lot easier to manage.

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.
