Octolapse: Snaphots before and after completed print

[PaWi20]

If this is a feature request describe it here

Most of the time, I use the "Smart - compatibility" or "Smart - Snap to Print" Triggers. Unfortunately, they don't take a snapshot before the print (empty print plate) and after the print, with all layers finished. I've seen timelapses where the last snapshot was taken after printing the shell surface of the print. As far as I understood, its also possible to use G-Code commands (@OCTOLAPSE TAKE-SNAPSHOT) to trigger snapshot and stabilization. For this I have to adjust my G-code with the trigger commands before/after the print as well at layer changes. But I also must use the "Gcode" Trigger.

It would be great to have the Smart triggers mentioned above in combination with the G-code command. In this case I only need to edit my start/end G-Code and can use all the smart triggers, that I really like.

Or maybe did I miss a setting that solves my problem to take snapshots before and after the print?

Version of Octolapse

Octolapse Version: 0.4.1

Version of OctoPrint

OctoPrint Version: 1.8.7

YES, I have thought about this. I may even add the ability to take 'before' and 'after' print snapshots in addition to allowing @Octolapse commands to be used in any of the triggers.

I believe I have it working. Try installing within the plugin manager using this link (get more->...from URL-> paste link -> click install button): https://github.com/FormerLurker/Octolapse/archive/refs/heads/devel.zip

Now you should find a new option within the 'smart trigger' settings (it will be set to 'enabled' by default):

Now, just put the @OCTOLAPSE TAKE-SNAPSHOT command wherever you want (start and end of print)!

Please let me know how it works.

Hey there. Thank you very much for your great work, especially for this complete plugin! I'm going on vacation in two days and I'll have to see if I can find the time to test. I'll come back to you!

I finally had time to test the new function we had discussed. It works pretty well and does exactly what I needed. Many thanks for that.

However, I had to rearrange my start G-code a bit to get a snapshot of the empty heat bed. At least in my case, I had the problem that I couldn't place the snapshot command anywhere in the start G-code. It was only recognized when an extrusion was made below the priming line. I didn’t want to deactivate this priming height (set it to zero), because in this case the first layer (e.g.: 0.2 mm) and its snapshot was not recognized. My solution works with the initial priming height of 0.3 mm and extrudes two more priming lines with a lower layer height:

• one as a trigger for this first snapshot command
• another priming line to wipe off oozing filament after the snapshot

Please see my start (and end) g-code below. I wanted to share this information in case anyone else is looking for a suitable solution.

Not sure if you've had feed back from a prusa slicer user, but I cannot get this new option to work.

Octopi 1.0 octoprint 1.9.3 new camera stack. Verbose Gcode selected. Added custom command @OCTOPRINT TAKE-SNAPSHOT within start Gcode before priming line

Selecting the option for smart triggers - compatibility and tick the Allow snapshot command option.

The first snapshot happens roughly half way through the first layer.

Switching to the classic Gcode trigger works with the command in the start GCode.

[PaWi20]

No, I didn't. But I tested a timelapse with the new camera stack yesterday and it worked as expected (Cura).
