Delete an object from a group while printing

[nkuck]

Is it possible to remove one of several items on the print bed while printing, in the event of a failure in progress? This has happened to me several times, and the ability to delete the faulty object would allow to save the test.

In a nutshell.....no!

By the time you're printing, the object or objects have been processed by the slicer and the gcode stream of instructions have been generated and written to file. The printing part of the cycle is simply sending these already written gcode instruction from that file to the printer one by one..

And if you're thinking that printing via USB is different to printing from a SD card....then they're not. Via USB, the gcode instructions are read by the software and squirted one by one to the printer. From a SD card, the printer does exactly the same thing.

Thanks, what I thought, but I recall reading something about one slicer having that ability.

I think octoprint or something like that has that ability. I have read about it.

This is a good reason why I stopped with the full bed prints for the most part.

You really don't loose much time by doing smaller batches.

Not surprisingly, S3D has been behind in updates that allow this feature to work with octoprint natively. With S3D it requires that you use a process per object.

Great feature request guys! You're also correct that the plugin for Octoprint can already provide this functionality for you. You can even use multiple processes per model thanks to the variable settings wizard. A good tip of you want to do that is to name your processes before splitting them into multiple regions using the wizard. This will help visually identify them in Simplify3D and in Octoprint.

Marlin firmware 2.0 now includes M486 commands which allow cancelling of individual objects. See: https://reprap.org/wiki/G-code#M486:_Cancel_Object

This feature can save lots of prints and should be something included by slicers.
