It would be great to see how many meters/grams are still on a roll without taking them out of the AMS and guessing. The printer must be able to account this.

Cool. I did not see that. Tx.
Why would that not work with 3rd party spools?
Frank
3rd party spools are missing the RFID tag.
If the machine takes in 10cm of a roll, it can still account 10cm of roll is used in slot 1. You donāt need the RFID to do measure that.
If you have 2 rolls of 3rd filament, how can the AMS tell them apart without RFID?
by slot number? You reset this everytime a change happens. I donāt the AMS to account for āfilament A in Slot 1. used 50cm. Changed to Filimante B in Slot 1.ā. That would be too much to ask.
Anyhow, as i am currently just using Bambu filaments, i am happy enough.
For example. You used 100 cm for spool 1 in slot 1 and you changed the filament in slot 1 for another spool, spool 2. Over some time you are using spool 1 again in slot 1, the AMS does not know this is the same spool (spool 1) you start with using 100 cm. So how do you want the AMS to get record of all the spools used filament. The only way the AMS can track the spool is the RFID.
It would be easy if it was possible to enter remaining capacity manually after replacing the spool.
You know that a mistake is made very quickly and you forget to keep track of it. Then itās better to keep track of it with a scale and an Excel sheet. Youāre making it so needlessly complicated.
What is missing in bambulab is filament management outside the slicer. If i could define āFilaA ā and these are itās parametersā and store this, when i switch a spool i could assign that spool to that parameter set.
The problem is not that this is hard, it is that filament mgmt for 3rd party filaments is non existent. But this is a solvable problem, and not even very hard.
As said, as i am currently using bambu, i am fine with that.

When I was printing with Creality printers running on Marlin I used a so cald filament manger with Octroprint/Octofarm. The only thing you had to do was selecting the spool you used. And how many times I forgot to do thatā¦ Only successfull print where calculated. Another problem was the spool could run on multiple printers so you had to use an external database. Eventualy I stopped using the fila manager.
No offense, but the fact that you usually forget is not enough reason to reject such a feature in general. It would be good enough for me. Yes, itās not perfect, just good enough.
It would be perfect if BBL opened their RFID system and let users create their own tags or at least reuse tags from empty BBL spools and allow to rewrite their properties like filament type/color/remaining amount and calibration values.
I would also argue that the bambulab target audience is not someone with a printfarm.
anyhow, i agree the rfid system is better, but as said - if that would be opened up for custom RFIDs, everything would be solved.

I would not call three printers a printfarm, but that aside. Keeping track of the spools via RFID, yes please. Manual input of meters/grams, no. But thatās personal.
Had not thought of that, i dont print much, so random rolls all over the place with various amounts leftā¦and then I want to do that new print job that might be 350gā¦ do I have 350ā¦ or 375, or 325.
a) I presume you need a fairly accurate scale?
b) weigh each and every spool upon opening. eg cannot assume 2 x eSun Rainbow Silks will weigh exactly the same for example?
c) moisture absorbtion? could this be a way to detect badily āsaturatedā spools?
One gram accuracy is close enough.
I use my glue stick to put a piece of paper on the spool to record weights.
Weigh the spool after opening the bag, before first use, and record it.
I assume that anything over 1 kg is the empty weight of the spool. That figure is close enough to estimate remaining filament.
But I also use weight to track moisture absorption.
DRY every new spool before use. Stop drying when the weight no longer drops. I have removed at least 2 grams (2 cc) of water from every new spool, some have lost 6 grams.
Some of that water weight is probably in the spool itself. I doubt the manufacturer keeps empty spools in a humidity-controlled environment.
I donāt have an AMS, most filament is weighed again before it goes back into the bag after use.
It might be dried again before storage, depending on the filament and how long it is out. A 760 gram spool of PETG on the printer for three days in 60% humidity recently lost seven grams of water before being stored.
Weight into the bag is compared to weight out to see if it has gained moisture (which it can), even with desiccant and with excess air sucked out. One or two grams I donāt worry about, more means it goes back in the dryer.

Only if you remember youself how much is left on each spool you removed and swapped. So keep a spreadsheet? Have a photographic memory? etc. lol Just look at the spools and estimate. btw there are capacity markers on some spools.
To find this setting go to filament submenu, little āgearā icon in the bottom right corner next to the ālittleā filament bars. Hard to NOT miss. just saying. Why not have a special AMS section in the settings?
You can do the Spoolman for 3rd party, and Bambu spools.
