I’m using a Bambu Lab printer with AMS, and I’m looking for a way to completely disable filament purging during material changes. My goal is to rely solely on a prime tower for handling transitions, as purging generates unnecessary filament waste for my use case.
I understand the AMS is designed to purge to prevent contamination, but I’d really like to bypass this process entirely.
Has anyone managed to find a solution? Maybe through advanced settings, G-code modifications, or a custom workflow?
I’d greatly appreciate any ideas or advice! Thanks in advance!
I appreciate your effort, but I believe there’s a small misunderstanding. I’m not looking for instructions on how to set up or configure the prime tower. My goal is to completely disable the regular purging process during filament changes and rely only on the prime tower for material transitions.
If you have any insights or ideas on how to achieve this, I’d be very grateful!
The best solution to this is to use an object as the purge location. You can enable this in object settings and it will use the object as a place to flush waste.
thx for your answer i tried both but it does not work for me i had the idea to tilt the printer for better automatic part removing but my P1S keep purging filament no matter what i try now im looking for a robot solution
With flushing volumes zeroed though, isn’t it only purging the distance between cut and nozzle instead of the ‘extra’? That’s what the standard purge is meant for - to get the extruder connected back to the nozzle (otherwise retractions don’t work properly). Flushing volume is the one that does extra for contamination reasons. Or are you religious about not pooping?
edit: if you really want to disable purge, it’s in the machine g-code section under printer settings. There’s a section “Change Filament G-Code” where it starts to check {if flush_length_1 > 1}. You can comment out the G1 commands.
