Skip object bug multicolor

Bambu Lab X1 Series
1

I was printing two objects on one plate - one single color, one dual color.

I had to skip the dual color object and only kept the single color one. The issue here is, that it kept adding to the prime tower and thus wasting material.

It even switched to the second color later, added a layer of it onto the prime tower and switched back since the second color wasn’t needed.

You can’t select the prime tower when skipping objects and it unnecessarily wasts a lot of filament

Whilst I agree that it would be perfect if they did stop switching in to ‘no longer required’ colours.

I think it would make the either pre-worked out or dynamic logic a lot more complicated. For example they would need to handle:

  1. Having to go through all of the colours used in remaining layers of remaining objects to work out which colours are ‘no longer required’.
  2. Replacing the ‘no longer required’ colour in the prime tower (if present) with a different colour.
  3. If at the time of the object switch off the ‘no longer required’ colour is the last colour in the current layer that would make completing the current layer in the prime tower even more complicated.
  4. Switching off the prime tower and all flushing if only one colour now left
  5. Removing one or more colour changes will also mean the flush lengths between the remaining colour changes will be affected and if not adjusted correctly might result in colour bleed between remaining colours.

Some of these complications could I guess be worked around by allowing the prime tower to be skipped too (if the user is willing to take the hit on print quality and colour bleed.)

I know this was last year, but I just had this very issue today. I’ve had my A1 for a week. I ran out of White and canceled two smaller parts to save the larger parts of my 30 hour print. Even when I ran out of white completely I still needed to load some other filament just for the color changes and purge tower. Shame to watch good filament just get wasted.

I read the Object Skip wiki and understand that it has to do with the other layers in the purge tower and and a few other things. It would be nice to skip a color or an object and prevent it from wasting filament. Guessing they’d have to figure out how to ensure the purge tower is divided into separate colors (like a grid or something). Thinking maybe with that the slicer could cancel the gcode lines for that particular color/object and still print on the purge tower for the remaining colors/objects.

Different side of this bug.
I was printing an 11-part project. After one part failed to stick to the plate, I skipped that part in Bambu Handy. When I came home from work, I paused the print to completely remove the failed part from the build plate to prevent any defects to the other parts. After resuming the print, I didn’t notice until it was done that the printer had continued to print the rest without the color changes, ruining the remaining parts.

I don’t think this is a Studio problem since I skipped the part in Bambu Handy (which is up-to-date) and paused the print manually on the printer itself. (Printer up-to-date too).

This issue makes me mad.

You can clearly see where the issue start.
Cryptex Wheel one complete without issue (printed before) and bad one (with skip function).

BUG happen again, only by skiping without pausing or whatever…
