3. AMS filament backup: the AMS lite will switch to another spool with the same filament properties automatically when the current filament runs out. These filament properties include brand, type, color, and nozzle temperature. If the AMS cannot find the same filament, it will display a prompt that the current slot has run out. To enable this feature, please check “AMS filament backup” on the AMS settings page.This function requires filaments with exactly the same properties. It is recommended that Bambu filament be used as a replacement for Bambu filament and non-Bambu filament be used as a replacement for non-Bambu filament.
It would be very nice and handy, if there would be a option where the color of the filament will be not part of the properties. With this option, it would be possible to print with leftover filament from the same type (like PLA or PETG, etc).In some projects I don’t care about the color of the printed object but with the current filament backup settings it is not possible to put 4 leftover spools to the AMS and let the print automatically print a object with all 4 spools.
I know, but it would be very nice if I don’t have to use the a hack of set all colors to the same. It would be nice if there where more options so that I can turn off the property for the color, direct in the software.
If I use non Bambu filament and use generic PLA for example, that would be already enough to use the leftovers (if color mixing is not a problem for the final result).
no matter if you have the RFID tag or not, you have to use a hack and set the colors for the different filaments to the same color, otherwise the filament backup function will not work. A much better solution would be to update the software, bring a extended option where the property “color” will be ignored for the filament backup.
To be honest, do you prefer to work with a hack rather than a real option in the software which comes directly from the manufacturer?
Looking at your reply you want a setting to use a multi colour ams to print multipule colours while using filament back up function which requires all settings to be the same , there are a few threads all with the same filament but with different k. settings .01 - .02 there is also a wiki page explaining why you shouldnt try to trick the ams , so im guessing its like that for a reason ( settings set as per default that the ams understands ? ) would i prefer to use a multi colour system in the way its intended ? yes and if need be i will act on the pause and change a filament in a like for like fashion .
as my first post shows, I use the “General PLA” profile for non Bambu lab filament and since it is the same General PLA profile for all PLAs I use for the left over, I’m currently not able to print with leftovers automatically because the color is a property which prevents from automatic filament backup. I mean if I do a multicolor print with Generic PLA profile there is also no issue and AMS changes between the different generic PLA filaments. So why not also with filament backup, in my opinion it makes no sense at all. So it would be very nice to have a build in option to disable the color property for AMS filament backup function.
How do you actually load all these scraps ? my suggestion would be to add a pause option while you`re slicing or add filament changes as its intended . And in all honesty id rather be there to act on a pause your filament ran out option, thats already built in
but I want to have it automatically without a pause, like you have it in a multicolor print. In a multicolor print you have also no pause. I want load all 4 slots with leftovers, use the general PLA profile (for example all 4 sppols are PLA) and start the print, no matter which color I loaded, the printer should print and if one spool runs out of filament automatically the next spool should be chosen and used. That simple I want to have it.
Multi colour prints pause its how and when they change colours to unload then load the print head, generic pla have no rfid tags so colour choice isnt or should not be an issue , so it looks like you already have what you`re demanding and perhaps its the user that is the issue ?
have you considered putting in a ticket about its functionality ?
Don’t get me wrong here, but to call it a user issue shows me that you did not read and / or understand me.
Once again:
add (for example) 4 NON Bambu Lab PLA leftover spool’s with different color on the AMS and chose “Generig PLA” for each spool (since it is not Bambu filament.)
make sure the setting “AMS filament backup” is enabled
start a print, start a print where it doesn’t matter that the object becomes colored in random places
the Bambu Printer while currently stop and ask you to add a new spool of filament if the filament runs out.
My expectation: There is an extended setting option for the “AMS filament backup” setting in which you can deactivate the color property. This way the printer would no longer ask you to insert a new spool, but would instead use the next available spool on the AMS since all 4 spools have the “Generig PLA” profile set.
I hope now it is simple and clear for you as well.
Running into this issue on daily basis: print started, filament run out, A1 waiting… but: 3 spools with same material, just different color, remaining untouched…
Would also be great to select the backup spool direclty on-screen instead of moving filament from 1 slot to another
95% of my prints I don’t care what color or colors they are. I just want them printed!
If I was too dumb to make sure the spool has enough filament on it, or as OP stated, would like to use 4 spools with 250g of filament for a 1kg print and they are all the same type of filament just go to the next one!
In todays case I had to manually unload the spool in 1 and flip it to 4 when 4 ran out.
Yes. I agree. I had the situation where different colours were in each locatioon and the auto backup failed. I was looking for a wat to select the color but its not there. I ended up physically swapping the filament spool for a different one. I wish I could have done it remotely.
I am guessing you probably know this by now, but incase you don’t, the way it reads the Bambu spools is with a rfid tag on the spool, not with a color sensor. It cannot read non Bambu spools.
I think I tried that, except when in the failure situation it is not possible to edit the filament colour. So, unless you plan ahead to do a workaround your solution doesn’t work.
