NEW Auto Refill update help!

[amv]

Hi all,

It seems as though Bambu tried to fix a problem but likely created another one in the meantime. I hope I’m wrong and I’m looking for your input!

I have two AMS units connected with various types of PLA and PETG installed (All Bambu RFID). In the past, when I had a partial roll of material, it would look for both the same type and color of material to use for Auto Refil. Now, since the last update, it will choose any color of the same material it seems. My example:

I have a patial roll of Black PETG installed at A3, a full roll of Black PETG installed at A1 and a Green PETG installed at B4 (why the system jumped to B4, I’m not sure, as there are many other rolls of PETG before this). Here is order for Auto Refill:

If I select A3 as my first roll, since it is the partial roll, how do I ensure when it runs out, the system doesn’t jump to green? Is this a glitch in their new update or am I missing something here.

Thanks folks!

Please post screenshots of the Bambu Studio device tab AMS set up to confirm your issue.

I cannot reproduce this.

I have two P1S printers with two AMS units each, both printers are running so I can’t test it on a two AMS setup.

I have one P1S with one AMS (the other AMS is in the box still), it doesn’t do what you are experiencing.

I have another P1S with two AMS units still in boxes, can’t test on that, no idea why I even mentioned it.

I will check again when whichever of the two completes their jobs in a few hours. I will test PLA and PETG just in case the outcomes are different.

Unless someone beats me to it of course.

My single AMS PLA test.

Based on your experience, I should have seen the Blue PLA in the mix.

Thanks for testing your system. Just so were comparing apples, I’m using the WinOS based Studio v 1.10.1.50 on a P1S w/2x AMS.

And to be fair, I am starting to think the software is functioning as they expected it to, but it’s not exactly logical. Using my screen capture from above, the logical order for these filament (in my opinion) would be A3 >> A1 >> Any other PETG

But ultimately, if they are now introducing multiple filament options as part of the Auto Refill feature, they should allow the user to select the order.

I am on a Mac.

With far too many P1S printers and AMS units, I still have them queued in their boxes.

It appears to follow the original priority which was nothing more than the numerical position in the AMS stack.

1. A1
2. A3
3. B4

Whilst not ideal, you could swap positions of A1 & A3.

The system needs a way to say; exclude this filament from this auto refill chain.

But, you have to wonder why it skips A2 & A4 if this truly is anything goes.

It is worth noting that the way the AMS guesses the remaining filament is not on by default and is unavailable to AMS lite users.

Ya, switching my filament position would be a quick fix for today, but really not idea.

When the Auto Refill was only designated to the same color/material, this was not an issue. If I selected A3, for instance, in the “Sent print job to” window, the Auto Refill grouping order would adjust accordingly. Now, it doesn’t appear to do that:

Just adding to my own comment here in case others can help. Started a print today, expecting that the system would use up the Black PETG that I have…because that’s what it says it will do:

Instead, it used up the last bit of black I had on B1, and moved right over to A3.

Please, someone tell me that I’m missing something here.

Thanks

You are not missing anything, it is broken.

After (above) saying I couldn’t reproduce the issue, I started suffering myself.

AMS Auto-Refill change breaks usability

Problem: The changes to the AMS Auto-Refill have left it as a dangerous feature that can’t be switched off without losing the original purpose. Scenario: AMS 1 Slot 1 - Unrelated Slot 2 - Unrelated Slot 3 - Black Slot 4 - Green Green ran out as I anticipated, and I went to swap it out and noticed the printer had swapped from Slot 4 Green (empty now) to Slot 3 Black. I have Auto-Refill enabled, but, this used to be identical colour matching. All filaments are from Bambu Lab and all were…

Ya, I’ve been away from this issue for a while…but it reared its ugly head again today. This time, it told me it would use the “Auto Refill” filament first…and then failed to do so. Since it’s not clear from image, B1(depleted) and B4 are both Bambu brand BLACK PETG HF. NOTE: If only looking at the filament NUMBERS not AMS LETTERS, it seemed to prioritize numerical order.
