Question My last few prints I have noticed that during a color change that my purging has taken almost a minute to complete. ) However, when I printed the model, it purged filament (about as much as a filament change) every layer despite not needing to change the filament. It grabs any left over filament in the print head from previous prints and removes it. As a result much less purge volume is required. cut_retract_length) that could be set per filament (or type). But I only had one roll of filament at the time. The spool itself got emptied entirely during the print, but the filament only just passed the AMS gear. It should be Hey 👋 I got my new printer, I love it, it feels so modern and advanced but immediately one thing stands out: there’s just so much wasted filament I am printing small models, repeatedly, I power my printer on and off, I only use a G’day. Usually 4 colors of PLA. The errors are varying: “Please remove the external filament from the extruder. On the first, using a Silk PLA the purge lines printed and some brims for the support printed, but nothing for the model. I’m new to the Bambu AMS Lite for the Bambu A1/mini. Im probably wrong but i assumed the prime tower was for I have a new A1; however the filament wiper doesn't appear to work properly. Enjoy up to 25% off on bundle purchases of aesthetic I have a multi plate project. Try putting the filament in another slot or try printing with a different filament “Simply retract 20mm to 30mm of filament just before cutting. You may need to move the Purge Tower to a more suitable location, unless using the 3MF. That amount can be minimized by proper “unloading” of the existing filament by way of the onboard control After the filament has fully exited the first-stage feeder, the AMS is still performing the unloading process with the LED status of the feeder in solid red (as shown below). Priming ensures a consistent flow after the switch, so that you don’t have under- or overextrusion artifacts in the print. I know here are some differences in how the two are sliced. I'd love to type up my own to quicken up the time it takes for color changes, but I figured I'd ask if anyone has already done this to potentially save myself some time but it DOES do something!! filament changes will swap the filament profiles properly (extrusion temp, flow rate, etc) i swear to baby zeus i added a feature request topic some weeks back asking for a non-AMS multimaterial workflow. The change filament makes it obvious that the rest of the print will happen with the other filament, but I Go to BambuLab r/BambuLab. This is possible that there is a broken filament inside the internal hub unit that leads Go to BambuLab r/BambuLab. - Filament inside. Some other multi-material / single-nozzle printers use a “purge block” for both purposes On average around 110mm³ (+45mm³ if you include the prime tower) of filament is saved per change. Jeepin95: So it sounds like the Im probably wrong but i assumed the prime tower was for priming and not purging old color. I purge to an object to reduce the amount sent down the poop chute. Realistically you can instruct the printer to flush the poop into an extra object and Hi, since two weeks I have some issues on my X1C with filament sticking on the nozzle during bed levelling. Everything will be going fine then the printer will stop printing, head head will go to the home position over the wiper. First my AMS did not recognize new filament via NFC. However during the purging process some filament can curl upward and stick to the nozzle. I spooled up a new print that would be with white filament. I’m inclined to leave it this way. Also seen plenty of people make stuff by melting it down in silicone molds in the oven. Print Profile. 0. I have it set to print the orange object first and then print the green object second. Zulkir here. And my printer is convinced that he got external filament from the spool holder. Poop bucket/filament waste/purge bin for the BambuLab X1 and X1 Carbon, probably suitable for P1P also. Some filament curls upward and sticks onto the nozzle. (In BL’s defence, not all was Bambu filament - but even within those changes they were off in half of the cases) 4 out of 56 changes were insufficient and needed more flushing There's a profile on Printables that claims to save 60% of flushed filament during color swaps. I will be printing a single color print with the AMS on my P1S. Wondering if anyone has developed a process to use cleaning filament on an X1C. None of my other printers do this, and they are just fine, I have also noticed that when the printer scans the first layer it then does yet another filament purge, I have quite a long list of parts to be printed, however, once these are done I am going to try and negate the purge and the second purge line and see what the outcome is, I will of course record the camera purging most of the waste into infil reducing purge amounts when swaping colors as the presets are very cautious and you can literally cut this in half on most filaments before seeing any color bleed printing multiple models that use the same colors, same wasted filament but getting 2 or more models out of it rather than 1 Sure, that is why we have filament profiles! BTW see also #2518 - this could be just another filament parameter (i. I think this is why it speeds up as its priming and then jumps right into the print. I think bambulab has cutback on the purge cycle time in firmware updates. I am new to bambulab studio. The original wiper just moves the filament around and cuts off most of the purging. By adjusting both these settings, you should see a significant reduction in wasted filament during filament changes. I have the problem as soon as I print something via AMS or as soon as the part is connected and the color selection runs over it. Sometimes the ejection lands in the plate causing print failure (movement, bad Below is an example of when I used the Studios recommended purge amounts. I changed it to 25mm³, and it seems to still come out pretty clean. It gathers and dislodges waste filament during different stages, including printer setup, pause and resume operations, and filament changes for multi-color printing. When you resume, the filament should load and then do the purge based on So I guess everyone who prints with PETG has encountered the issue of the wiper not wiping the filament off the hot end properly and dragging PETG strings across the print. Bambu printers dont use a prime/purge tower instead they poop and you use the prime tower just to prime, making it a way less dense object and decreasing the size of it. Mine has broken, though I haven’t taken a look to see why. I understand concerns with throwing away filament especially the expensive stuff. Sorry. Every time when the print starts there is purging. I wanted to make the lower section a bit deeper so it could hold more waste as I'm lazy and don't want to have to empty it too often. I think it is not the origin according to the tests I have done. Thanks. Using ABS currently. I’m having the same problem. Add your thoughts and get the conversation going. I’ve observed that oozy filament often gets hung up on the wiper or in the poop chute, as do larger filament purges. I dont have a solution tho. I am starting to notice some degraded prints which in part may be to a dirty Well there's your answer. If you reduce that multiplier to . My last print on my A1 was with red filament. I’m looking to increase purge flow rate to a very high amount and slow down the speed of said purge. In my naive mind I thought this might be an issue since the AMS wouldn't be able to pull back the remainder when the Here is a post to gather ideas on speeding up multi-color printing. So I decided to try and The purge line is to set up the pressure in the nozzle before the print. Also, because the mechanism is no It can go through all of the auto setup steps and even purge filament just fine and change filaments, but once it gets to the process of Calibrating Extrusion Flow, it stops pushing filaments. I’ve also noticed an increase of purged filament being flung onto the bed and not into my purge bucket I made. It happens every time (I pause for inserting magnet). Even then i *BAMBU A1 *ISSUE HAPPENS WITH STOCK FILAMENT & PRINTER PROFILES Recently I’ve been having a issue with the printer purging a excessive amount of filament when starting a new print By excessive I mean it’ll Purge filament for 30 seconds or more sometimes I don’t remember it happening when I first got the printer.

What I'm thinking of doing is while the printer is printing, swapping out the filament with a similar but different color. That didn’t work either. Parts Required: 1. Welcome to Bambu Lab! Here we discuss everything related to Bambu Lab 3D printers. This would make Bambu filaments even more attractive as you could supply values for them (eg. It’s possible to do while it’s cutting the filament to pull it back into the AMS. 1 - Use th T g-code to : - cut the current filament - go to the purge location - unload latest filament - load your cleaning filament 2 - then purge a little to replace latest filament I checked the printer and the filament was indeed broken inside the AMS Lite ptfe tube. That being said, this code *should* properly pause at the filament change. Just retract 20mm to 30mm of filament just before cutting. Its meant to make sure the nozzle is clean has filament right to the tip, which does seem redundant considering the nozzle wiper. You can also use PETG for PLA and just PLA for PETG. 1g of filament. ” Hello, It seems that it should be fairly easy to reduce the amount of filament lost through purging by 50% to 75%. This was a loooog print time due to all the filament changes, and to make matters worse, to justify the purging waste, I printed two of them (boy did that bite me I'm familiar with slicing a pause for filament switching and have switched filaments before when they run out. When I first got my printer, I’d hear a horrible clunk when it purged the filament and wiped the nozzle. The tower is not a purge tower it is a prime tower and is used to bring the filament back to the right pressure and avoid ruining an object. adaks October 27, 2024, 2:41am 3. 2 Likes. Its a prime tower not a waste tower though. Installation Learn more about the replacement of the Purge Chute on Bambu Lab Wiki. Any little bits left over can grab filament and pull it to one side and keep it from coming detached by the nozzle wipe. YES YES YES such a great idea ! @NoahKatz I think this is already implemented as Print per Object option. I have it set to print the lighter color first and then switch to black. This is stuck and must be “unlocked”. The purge line only uses 0. JonRaymond June 8, 2024 and vice versa. 3D Printer > 3D Printer Accessories. Il rassemble et déloge les filaments usagés au cours de différentes étapes, notamment la configuration de l'imprimante, les opérations de pause et de reprise, ainsi que les changements de filament pour l'impression multicolore. I've examined the wipe and there doesn't appear to be any defects. It says that much after slicing (Bambu Studio says that there will be 0 filament changes. . Each layer it comes back to do a purge but the nozzle doesn't make contact with the wiper and takes a string of filament over to the next spot which messes with the print. It has come to my attention purging large amounts of filament would likely decrease clogged nozzle issues, which I am having annoyances with because of switching around vastly different materials. Reply reply starrtech2000 Last night I tried to print a figurine and it mixed the support material in with the primary filament. On a print where there are a lot of layers that don Personal found the printed chutes were A: waste of time and filament B: Too small/"perfect sized". I’m attempting to find a solution for support of a long print in PA6-GF. Are bambulab going to improve the It's a prime tower not a purge tower. If you haven’t change the filament, it’s save to remove/comment out the code. The purge line might take some of the poop off but most of the time the stuck What I am finding is about 30% of the time, the purge blobs will catch inside the chute somewhere and clog everything up I’m printing a lot of . After the filament has fully exited the first-stage feeder, the AMS is still performing the unloading process with the LED status of the feeder in solid red (as shown below). Reply @theCADdesigner. They favour those who are using it efficiently, rather than what is actually best/correct, or what came out first. I’m not sure what happened. New comments cannot be posted. If an AMS is to be used later, please connect the PTFE tube to the coupler and click the “retry” button. Depite this last lower change of color, the slicer continues to print a purge tower even if it if nit necessary. ===turn on filament runout The default settings print outside lines first, so the machine will purge all the excess color out to start a new color on the outside. I know the printer needs to purge some Depending on location you may be able to find some filament manufacturers who have recycling programs.

In this video I show how to calibrate your filament color changes, speeding up your 3D print I made a model on printables a couple of months back, which saves tons of filament during purging. The difference is a waste tower would be significantly bigger as it would have to have the purge go into it as well. 2 nozzle prints that run from 8-16 hours on my X1C. user_1437127406 November 27, 2024, 5:51pm 1. I wondered because my slicer showed the travel moves to the purging mechanism (activated travel moves in the preview) but when printing it didn't made those moves. This filament guide offers a comprehensive comparison of properties, application, and printing requirements for Bambu filaments, aiming to help users select the best-suited material for needs. IMPORTANT NOTE: I was told on the discord server that glow-in-the-dark filament should not be used in the AMS. ;===== nozzle flush/poop routine ;M109 S250 ;set nozzle to common flush temp ;M106 P1 S0 ;set Fan Speed ;G92 E0 ;set extruder position ;===== *** filament poop (standard E50) ===== ;G1 E50 F200 ;move extruder ;M400 What I am finding is about 30% of the time, the purge blobs will catch inside the chute somewhere and clog everything up I’m printing a lot of . You send in your waste and Hello. I’ve been doing filament switches with high purge volumes and the chute appears to work better in spite of the busted part. I’ve increased the retraction length for the filament, but that hasn’t stopped the issue. So it sounds like the primary advantage to enabling this is that it also enables the option to flush into infill or support? It seems without the prime tower enabled those options go away. Left printer on a six hour overnight run and woke up to this. There is another sensor at the back of the printer that detects whether filament is present. Orca Slicer and BambuLab P1S will not flush filament when using print by object or when prime tower is disabled By bed isn’t sticking very well but I’ve been using 3d printer glue and it helped. I have some purge towers that use between 1-18g. Replying to @GuyH77 : its PLA Sparkle Royal Purple, Spule (1.

That way it purges twice. r/BambuLab The screen indicates it's "purging old filament", but the filament in the tube is brand new and was being used 5 minutes prior for a print, so there's no reason to purge so much of it. Follow. Press unload; Repeat if necessary; Most of the time, once is enough because since I unload Here's an interesting tweak for reducing purge: https://www. Everything works well during the bed levelling phase where the nozzle hammers to the build plate. For me, this is just part of how it works. While experimental, this solution showcases the community's ongoing efforts to find innovative ways to minimize filament waste. This seems to happen on almost Easy ways to improve this: 1- increase layer height 2- the flush is going to be this whether you print one or print 50, so print more than one at once 3- minor gains on reducing purge value After wasting a 600g print + 50g flushed filament by reducing my purge value too much that’s the real waste there. The slicer does the math on purge volume automatically. The wiper is ineffective because it can’t reach the filament stuck there. Could be a way to lube inside the shute, I had thought about finding something but never really looked into it. 00. 00 firmware update to my A1, I observed a weird issue where it started to purge nonstop during a filament swap. I know you can use the pruge matrix to reduce waste, but if I finished printing sth in white, and then print sth else in white, there shoulb be no need to purge. This will randomly happen several times during a long print. 3. When is try to unload he alwas This filament guide offers a comprehensive comparison of properties, application, and printing requirements for Bambu filaments, aiming to help users select the best-suited material for needs. I have started a model with two different filaments. something like the ‘pause’ or ‘change filament’ features currently available, but more complete so we could ‘pause AND change There is filament in the PTFE tube to the printhead. 2 The broken filament inside the AMS internal hub unit or abnormal sensors. Here's how we recommend handling the waste: Properly dispose of the filament waste by discarding it in Our new "Long retraction when cut" feature can save up to 25% of filament purge volume during filament change. com. 10. Olias October 27, 2023, I was skeptical at first but have found this Purge Shoot Extension to really cut down and almost eliminate the purge filament that doesn’t make it out the shoot. It only lets out like 1cm from the nozzle during that part of the process, then starts rubbing the nozzle around without actually extruding or printing. It’s not just the purge poop, but the left overs from calibration and some failed prints all in all it doesn’t add up to that much but if there was a economical way to turn this back into filament for times that I’m “prototyping” something or printing something that I just don’t care what it looks like color-wise, then it would be nice to be able to reuse it. I always use PLA from eSun or Bambu. thedevilsjester September 15, 2023, 1:35pm 6. StreetSports September 8, 2023, 8:49am 3. Despite the fact it does indeed skip printing the smaller object, it still performs filament changes, purges and prime tower layers using the colour it doesn’t need anymore. Bambu Lab X1 Series.

But 2 days ago i experienced a strange problem. Given that this method of printing is in its infancy, I see a lot of room for improvement. I use both purge objects to reduce waste and a After the pause, when it resume, it reheat the nozzle, purge about 1 cm of filament and does not wipe. 5mm hex wrench; Lighter ¶ 1 I'm having problems with the filament flushes not actually entering the poop chute, but instead being left on the ledge by the print surface - which occasionally get dragged to the bed, ruining the print. The poop is the purge When printing multicolor, it’ll change colors multiple times per layer, so a flush object would purge the filament into an object rather than a bunch of little poops of filaments. Filament. 2. This block gets extruded before printing to ensure consistent flow. 0 is now live on GitHub! In this version, we have improved the purge calculation to accurately save the purge filament volume. kucpk djae chg mpuj ujyc qzbsptm ddo ibdl ulsy ypce
