Hi First of all I am So Grateful for answering me when I was so Frustrated and tired. You know sometimes when things do not go your way you have to leave everything alone and come back to it at a later time, and in my case I have learned that there are having many trouble with these kind of Printer, but Hopefuly when You learn really how to, things should go much smoother. So Me deleting what I wrote before was just it was Unfair to Bambu, before I really learn it and give it a Chance, and I thank you for all the help you are providing for people.......:) GOD BLESS...............
@user-yz3pl5sb7z Did you get sorted then? Hope so. I know sometimes a problem just needs a break to come back at it fresh and you see things you missed before. Thanks for the comment, and happy printing.
Most of my issues are from the bambu filaments when they get low. I printed some weight spindles filled with BB's to go in the centers. Also, printed the caps with short PTFE to keep the plastic funnels from getting worn, once those wear the filament will jump off the gear.
When I first got the AMS I printed a Bambulab spool (@2:10) but I did so in CF filament they provided. It was seemingly too abrasive for the AMS which they now recognize - so don't run CF or any abrasive material (or TPU) through the AMS. As a result the Bowden tube on slot #1 was worn prematurely and it fails to recognize the filament possibly due to debris in the Hall effect sensor in the funnel. While doing multicolour swaps it will often stop and report it can't load filament and I have to manually feed it in. I am replacing my Feeder Funnel today to see if the sensor is the culprit.
Hi Philip, thanks for the feedback. Yes, for me the PLA-CF was brittle and snapped in the tube after one feed and retraction, so I stopped using it, instead using the Prusa MK3S for these types of filaments. The AMS is great but its not suitable for every filament and I think this is the main cause of the bad experiences people have with it. Hope you enjoyed the video.
I used to get the failed to retract error quite regularly when I first got my X1 Carbon and AMS but could never see any physical reason, but then one day it just stopped happening, I was using Bambu and Polyterra filaments in the AMS, by the way I am pretty sure that Bambu filament is exactly the same as Polymaker filament but a bit less expensive, once my Bambu filaments are finished I will respool my Polymaker filaments onto the Bambu spools, I also had issues with roll ends snapping inside the PTFE tubes, I am thinking of making some spools with fatter middles so the radius of the bent filament from the roll ends are not so tight.
Hi, I just recently bought a P1S and something was wrong with the AMS I thought. After troubleshooting, I switched the AMS and cords with my X1C and realized there’s nothing wrong with the AMS. But the AMS connected to my P1S either one. Somehow it seems like the printer is not turning on the buffer hub to feed the fillament. Do you have any suggestions how to fix this just wondering?
@ChristopherStarling-rr4dv Firstly nice you can do that test and that definitely narrows it down. Is it just the P1S does not see the AMS? Did you swap out the cable connected from the filament buffer at the back to the Printer? Check the cables are all seated correctly. You could try swapping the filament buffer, I believe they are the same and very easy to swap, only 2 screws. If you have a faulty filament buffer, I would log a ticket with Bambu Lab and see if they will replace it.
Hi my AMS constantly blinking red when connected to Bambu X1 carbon as I insert filament in one slot it tries to pull and after sometime it rejects( retracts ) the filament from the AMS unit and this happens with all the 4 slots. Please suggest me a fix. Thank you
@beyond_desi7719 Hi, could be some filament stuck somewhere in the tubing, either in the AMS, the Filament hub at the back, or between the filament hub and the print head. You can watch it go through the tubes to see how far it gets. I had an issue last week and I removed all the tube and couldn't find anything. Then I gave up and decided to remove my Hydra AMS mod and go back to the original. When I started removing the tubing inside the AMS, out fell a small piece of filament that was stuck in the feeder at the back of the AMS under the tray. So checking how far it goes is where I would start. Second thing you could look at is, are the reels getting jammed, not rotating. If so, is it the right size to fit the AMS slots, are all the rollers in place or have any of them poped out of their slot and are skipping. But from your description it sounds most like a jam somewhere, or a faulty feeder motor or hub. But rule out the jam first. Let me know how you get on.
Hi thanks for your reply… when I put the filament it pulls it and push it backs also all the sensors blinking red. Secondly I can’t see any filament going through the tube please advise
@beyond_desi7719 if all 4 feeders in the AMS are blinking red, that is specifically a communication error between the AMS and the printer where the AMS is getting power but not connecting to the Printer computer. You can trying disconnecting and reconnecting the data/power cable from the back of the AMS and see if its fixes it, you could also try plugging it into the second slot on the AMS. If that doesn't fix it, I strongly recommend opening a ticket with Bambu Lab because its possible you have a faulty AMS or Feeder Hub and to ensure you don't void your warranty, you want to follow their instructions on any tests/fixes in case you break something.
My AMS isn’t sensing that there is filament in the A2 slot, I don’t know how to fix it. I’ve tried taking the filament out and re-entering it, it didn’t help. I have a p1p
@vanessasimms2399 You might have a faulty filament sensor, you can get a replacement AMS Feeding Funnel for slot 2 which has the filament sensor, its under 10 euro. Or you can try a whole AMS First Stage Feeder which is about 30 euro. But no certainty it will fix it. I would recommend opening a ticket with Bambu Lab support.
I absolutly hate how many times the AMS errors out because of the spool. I use mostly cardboard spools with PLA printed rings like most people. I feel like sometimes it jams itself with the way it unspools and knots itself up... kinda like in one of your clips. where it will fail to feed or unfeed
Hi Justin, yes, when it starts doing that its extremely frustrating, especially if you left an overnight long print only to come back and see it error'd out moments after you left it the night before... I would check the reel is inside the 69mm width all the way around, and if there is a join that its not causing issues with the rollers in the AMS. Its very sensitive and can overload the motors easily. Also I have seen issues with the print head extruder where the angle of the PTFE going into the extruder will bend too much and cause an overload on the AMS motors trying to push the filament around the corner. You can try adding the following, it did improve mine... www.printables.com/model/338073-bambu-x1-ptfe-extruder-bracket-ams-error-fix . Hope you find a solution.
@@T8Maker It’s super annoying and then when you get an error it doesn’t actually send a push notification to my phone. On big important over night prints I wouldn’t mind being woken up to fix an issue right away!
Can someone help me understand why I haven't gotten a printout of my Ams on the X1c since it arrived? I have tried 3 different Filaments and each time they clog the extruder with the error "unable to pull back Filament." I have tried both cardboard and plastic spools. Both Comgrow and Overture. It's very frustrating. I am printing PETG with a temp of 240c at the nozzle.
@easylivingsherpa I am not familiar with these filaments, but after googling them, based on the price of them, its possible they are not the best quality filaments. Cheaper filaments can disintegrate inside the AMS or in the extruder in the print head where the cogs feed the filament. Not pulling back filament is one of a number of issues, do you get the error straight away when you try to print? or is it after a while of printing on change of filament? Is the filament stuck in the machine and how far into the printer is it stuck, i.e. in the Print head, in the ptfe hose between the head and the feeder at the rear, the ptfe hose between the rear feeder and the AMS, or inside the AMS system itself?
I have 2 X1 Carbons each with an AMS. They both have this problem all the time. Filament type doesn't matter. Its a design issue that Bambu Lab doesn't have a solution for, so they try to sweep it under the carpet until maybe, in the future they can fix it. @@T8Maker
