Live Ignore

[Mephisztoe 0]

I was wondering whether it might be possible to implement some kind of "Live Ignore" feature.

 

Imagine putting more than just one object onto the bed and have your printer work on them.

Sometimes, it happens that one ore more objects fail during printing with the result that in most cases, everything on the build plate goes down.

 

So what if - once you happen to notice that one object is failing, it would be possible to let the printer know to ignore this object while the rest will continue to print?

 

Furthermore:

If a connected camera would be able to recognize failing objects (due to failed adhesion for instance), it could be possible to automatically ignore that object during the rest of the print...

 

Thinking about it, this seems to be more like an OctoPrint or Firmware Feature than something, Cura could be doing...

Not possible in Cura as it is.

 

About the only conceivable way I can think of doing it in Cura which might work would require making a plugin that allows you to manually (no way to do automatically) stop a USB print and move to the next model, but such a plugin would be complicated and USB printing receives little attention because it's mostly a legacy feature which is mostly unused (because it's a lot less reliable than putting your g-code on an SD card or whatever input your printer takes).

 

There's no way to do it in g-code, so it's not possible while slicing or in a post-processing script.

 

Automatically doing it by connected camera in OctoPrint or firmware: theoretically possible but a lot harder than it sounds. You'd need to use some sort of AI image processing to detect a print failing, compared to a pre-generated render of what it should look like at every stage, which is extremely computationally expensive..

See this OctoPrint plugin for example:

I believe the CancelObject Plugin for OctoPrint is something, I will have a look at. Sounds promising!
