I am running a print farm with a couple of AMS supported P1S’s. They all run from a gcode on the SD-card (not .3mf or .gcode.3mf, actual .gcode). This all ran fine, until at a certain point my AMS’s stopped switching to slot 3. Not a single AMS, but all 8 AMS units give an error message after emptying slot 2 “AMS Slot 2 Empty, switched to a slot with the same filament”, and then “AMS Slot 1 Empty”, after which it pauses the print. I resliced the file using the most recent Bambu Studio with a printer selected with all 4 slots filled and set up for auto filament change, but that did not solve the problem.
I also reverted to the last known file that worked, and that did work fine. However, I do not want to keep on using that, as that material is more expensive.
Anyone with the same problem? Any ideas on how to troubleshoot this further?
For future reference, the issue has been resolved thanks to BBL support!
Hello,
Thanks for your reply and for providing an update on the issue.
The reason this is happening is due the file sent to the printer already has the AMS mapping of Slots 1 and 2 are programmed into the g-code during slicing, therefore changes can not be made to AMS Mapping settings once the file is sliced. If you wish to use different AMS slots, perform the following steps:
After inserting the spools of filament into the AMS, please use the Bambu Studio software or Handy App to verify they are correct, or if using 3rd party filaments, configure the filament information here before proceeding.
Once this is done, go to the Prepare tab in Bambu Studio and click the icon pictured below to sync the AMS settings with the file to be sliced. Once this is done, try re-slicing the file and sending it again.
