Load+Unload bug in new firmware

Here’s an interesting bug I’ve found in the newest firmware.

  • Have filament loaded in from the spool (I.e., not the AMS)
  • Navigate to “Filament”, select the spool, then select Load. This is the first bug; if the filament is already loaded, it should not be possible to load it again.
  • Then select “Unload”. This is the second bug. An Unload operation should not be possibler while the Load operation is in progress
  • Eventually the “Retry/Done/Close” dialog for the load operation will pop up. Select “Close”. This is the third bug. Hitting “Close” will leave the printer in a state that looks like it’s still in the Load operation, the screen will show that a Unload operation is queued up, but nothing happens.

A 3-in-one!

I hope you opened a ticket on that one.

The forum seems like it’s the right place to report bugs that I don’t need immediate support on. After all, there is a “bug-report” tag.

@SirWill , @BambuLab , could you comment on this?

Speaking of which, I’ve found another bug that I think is just another manifestation of the bug above:

  • Have a filament loaded from the spool.
  • Start a print job from the slicer that uses the AMS.
  • The printer will have you remove the existing filament.
  • Then nothing happens forever. A power-cycle is required to get the printer functioning again.

Never had this issue.

There are a couple of BL employees that monitor this forum, but do not respond to all “Bug Report” tags. If you find something, open a ticket. Best way to solve it for everyone if it is indeed a firmware issue.

Sure the bed or hotend weren’t heating up? It doesn’t look like its doing anything while it waits for that.

I’m quite sure about that.

Update: Turns out I hit “close” rather than “retry”.

  1. I think “retry” is a poor label. Perhaps “re-check” or “Done” would be better for that dialog.
  2. It’s still a bug that hitting “close” makes the printer useless.
