Flow dynamics calibration bambu reddit. Even better would be to calibrate per color as they can behave quite different. Aug 22, 2023 · Have to cancel calbration to coontinue to Flow Rate Calibration 2 or to find somewhere to input K Factor; Actual results. Hello ! What should I do ? None of these are very Cannot Complete Manual Calibration (P1S in 1. After running Flow Dynamics or Flow Rate calibrations, I never get the option to click next to record the K Factor or Flow Rate number. If it's a bigger difference (I'd say 10°C or more Edit: Additional information - Bambu Studio doesn't show any option for "Auto Calibration" in the Calibration tab for my printer. bambu-studio. 4mm and . 015, based on the results of the test print, but I’m not sure if that got saved, and if so, where I’d see it). The flow calibration feature at the start of prints is to allow the printer to get the ideal extrusion specs to apply to the rest of the print. Definitely not generic pla settings. Early April the flow dynamics calibration ticket (actually it started as a ticket about it making some chattering sounds on fast circles) gets updated saying they'll process my heatbed replacement. It only saves the last calibration. The flow dynamics values are created by running that calibration under the calibration tab. I am trying to print some miniatures with the 0. In the future I hope they allow for flow calibration saved for each ams slot. Any thoughts? The documentation on that is limited at best. You leave this off when done!! It also speeds up your print start by a couple The texture can screw with the lidar. this was me until I wanted PETG that printed as close as possible to PLA. Give it a name like "Overture PLA Matte". But during manual calibration, it is possible that it could have been set to 0. Calibration bug in Slicer 1. This has happened twice now. 0xLooted. But given that the flow dynamics calibration only requires access to the purge wiper (and is not done on the bed), I don’t know why it couldn’t just run the calibration into the purge wiper for the 2nd, 3rd, etc. Generic PLA and then calibrate the filaments flow control and flow rate. I was thinking about saving for the P1S for my first 3d printer and it looks like the P1S doesn't have something like that. 020). You only need to do a new calibration if you get a new brand or type of filament. This happened 2 times. 15 (over extrution), and made sure, the checkbox pyrotechnicmonkey. I figured that the calibration speed is separate to that of the slicers defined speed. 6mm nozzle into my P1S, I've been getting various forms of over extrusion on the surface, even after calibration multiple times and reducing the flow, I still end up with this top surface on gears or anything with a lot of small details. You can select it as an option on the Send Hey All, Might be a stupid question but im new, i downloaded Orca slicer to run their calibration tools for a filament i was having issues with. The calibration page doesn't acknowledge that the printer is doing the test. I think that would allow flow calibration on the official textured plate. I'm trying to calibrate it for petg on a . 4) Bambu Lab Software. Flow Dynamics Calibration Returns to 0 on printer restart. I am not refering to "new" filaments, but filaments in the AMS which have been flow calibrated in the same slot without any changes. Disabled the flow calibration (on the X1C. 96 flow (lower than generic 0. So, I've been tuning my filament. dried the snot out of it, for like a week at 70c. I think the auto calibration is only doing PA calibration at best. 98) and around 0. I always do the bed leveling and flow dynamics calibration before a print. The documentation is not all that clear on if/how well this works with the Bambu Lab Pei sheet, I assume because it is not smooth and this messes with the LIDAR. I would highly recommend to also calibrate flow rate and max. I wanted to ask if I print directly from the phone app how I can set/change the K factor of the filament (that I got from the flow dynamics calibration) 1. Picked up a new filament, type and brand, so I was going to do a calibration. I was calibrating filament on my P1S, flow dynamics, OK, K 0,03, but the second process in Flow rate calibration in Bambu studio failed right before end where I should put number of best printed field. Use the smooth sheet for flow calibration, then switch back to the textured sheet and don’t rerun flow calibration. Any help is appreciated :D. ADMIN MOD Flow Dynamics Question Hey guys, ranges to be wider in the calibration settings, then Nov 21, 2022 · Bambu Lab X1 Series. On the A1 it just seems to add the value to the AMS slot and doesnt save it with a tag, so on the AMS section of the display it offers me default but none of custom values are show. Any ideas? Running flow dynamics calibration on the A1 mini and have never seen this type of behavior before. A spool of 35% RH Bambu PETG needed a much higher K factor (K=0. The pattern is printed by the printer profile startup g-code. Cannot find the value anywhere and its Handling extrusion at points at which the nozzle changes direction is controlled by the pressure advance parameter. ) Swapping through the four different build plates I purchased. Is active flow compensation. It just says that it's auto-calibrated. Before on my Ender I used to do the hollow cube calibration. Add a Comment. 060 in a few cases) whereas a recently dried Bambu PETG was only K=0. 031. 02 and 0. In my case, -3 looks the best. New Flow Dynamics Calibration question. If you search in this SubReddit and YT you'll find that the problem is mostly solved, the flow calibration works on the textured plate. So, turning on “Flow Dynamics Calibration” checkbox before print will make use of the auto-calibrated value, and it will override the Rethink automatic flow dynamics calibration. Troubleshooting. 1 or 1. Google hasn't been of much help. Raised the bed temperature to 60-65c for the Textured Sheet. The only lines you need concern yourself with are the back corner, and the very front of the bill plate which is the purge line. It's just there as a visual reference. But then you need a different one for Hello, I'm trying to understand the k value and dynamic flow calibration. Hey, so I cannot find any info of which acceleration value is being used for a builtin Flow Dynamics calibration. 948, and K factor 0. Easy. Currently only one. Pictures of boxes and shipping notices are considered low-effort and will be removed. I was going to execute a manual flow calibration for it (the automatic method mentioned in the help I assume that is only for the X model) , but reading the wiki carefully I got to the part that says that the textured PEI plate that comes with the printer shouldn't be used in Manuel flow calibration procedures. If you used the lidar automatic calibration, you need to make sure to do it on a flat build plate, it doesn't always work right on the textured plates. 3, calibration checkbox on. Use orca slicer, it has better built in calibration tests, but Bambu is also alright for You can calibrate both flow rate and pressure advance in Bambu studio under the calibration tab. FLOW RATE CALIBRATION. Thanks everyone! EDIT: Increasing bed temp to 100C and turning off all fans helped significantly, don't need glue or even a brim! Thanks for your insight! I'm still a little bit worried because the way the A1 mini calibrates flow seems to be really different from the X1 in which a optical method is used. I am only asking this because I can't seem to find it noted in their changelog. 4 nozzle. Flow dynamics, which is the K value also known as pressure advance is set on the AMS slot in the device tab. 00. You need to manually tune flow dynamics, and sometimes even flow rate. All things related to Prusa 3D printers. Someone more knowledgeable than me please confirm. 4mm nozzle K=. Slowed down the first layer by 20%. Printed with Bambu PLA Matte with a 0. Yes, the gold reflective sheet is not compatible with the LiDAR scan. the auto-calibration was garbage. 6mm nozzle K=. 00 You may not be Tune your Temps first, although a temperature tower doesnt really tell you much on a fast printer like this. (a) running an auto flow dynamics calibration alone through the calibration tab (b) checking the box for flow calibration before a print? Is the idea that I can do (a) and save a new profile for a filament so that I don't need to (b) before every print? Here we discuss everything related to Bambu Lab 3D printers. I did a filament calibration last weekend and didn't have this issue. Hello Reddit community! I'm currently working on calibrating the flow rate for a project and would greatly appreciate some guidance. It seems so obvious that I don't really understand why Bambu don't sell a plate with this already done, so perhaps I'm missing something. The Flow Rate calibration tool will step you through the test with an option at the end to save the value in a new filament profile. Flow ratio at 0. Edit: Spelling. The value is saved and available in the material selection in the printer's menu. 2 Nozzle - I did not have any issues with Bambu Labs PLA Tough. 025. I also understand the system has the dynamic flow calibration you can do. The last flow calibration is saved until you rerun it. I think yes, probably flow related and could be a result improper calibration of the following contributing factors: extrusion So I went back and did all the calibration. I can't do the Manual Flow Dynamics Calibration. 8mm nozzle Smooth plate Bambustudio flow dynamics calibration flow rate calibration first, then Printing from the app (K factor) Question. The Flow Dynamics Calibration looks like in the picture. Not a single line on here is correct. I only do flow dynamics calibration, but you could also do the flow rate calibration. This is the same as pressure advance in Orca Slicer and elsewhere. I have attached an image in this post for reference. PETG . The result tells everything: 1 has slightly over-extrusion on the edges. But here I need to indicate which piece feels "smoothest". • 6 days ago. 20 instead of 0. Had this problem last night, i updated to the newest release of My understanding of what happens is: During flow calibration the printer puts down some stuff and then it looks at this stuff with the LIDAR. Most is rated for 100-150mms max. Stay tuned for September 20th Bambu Lab new product release to witness the dawn of next generation flow control solution. My confusions comes from no way to change the K value in the user presets for the filament but i have to select a user preset to be used for the calibration. The flow rate on the other hand, which is usually Bambu studio flow dynamics calibration help. I thought with the new updates in the software when you run a Flow Dynamics - You perform the steps. On my machine, Lidar really only helps with first layer defects and even that is hit or miss. (Pass 1) - Pass 2 just fine tunes, I haven’t seen a difference yet, but some filaments need it I guess. This is the part I'm having difficulty with. I normally use the Engineering plate or High Temp plate for the automatic PA calibrations. Does anyone know why it keeps saying factor k failed. But for most prints it will still handle 250-300mms. 14. I only have the textured PEI plate on hand right now and noticed the Flow Rate calibration has the textured PEI plate as an option in the 'plate type' dropdown by its missing from Flow Dynamics. 033. The filament doesn't change during this time so I would assume the K values wouldn't change back to 0. BluDolphin808 P1P • 4 mo. 18 layer height profile. Only other change is 15% Gyroid infill, but the rest of the settings are stock. This time you're looking for the smoothest overall plate with the least ridges. I am having this issue with both flow dynamics and flow rate calibration. For context I have done flow rate and flow dynamics calibration on top of the Bambu ASA preset inside Bambu Studio. But anytime I want to send a test cube or Cali dragon it'll say "successfully sent to printer" take me to the device tab and the thumbnail will disappear along with I used the BS-SF PA and flow calibration on the . 1 and 1. This is especially apparent when running Flow Rate calibration. ThePie January 23, 2024, 8:36pm 1. Picked the Textured Sheet in Bambu Slicer. ¶ Two modes of calibration. But there is some confusion: I've tested it, by manually setting the Filament Flow Rate in Bambu Studio to 0. I’m also wondering if there’s under-extrusion going on. 034 K (PA), after calibration. 03 pressure advance values. 2 is a complete mess with everything looking like melted. Hello, Community members. 6mm nozzle using PLA and PETG and found no substantial differences. This was printed with PLA+ at 220 initial layer and 210 rest of layers on a 70c A1 Calibration. 05. If you ran the flow dynamics calibration manually, double check that you didn't miss a decimal place when entering the K factor (like typing in 0. Flow Dynamics Calibration has two modes: manual and automatic. However, auto calibration can be done on the machine screen. Is there any word if Bambu Labs is working on supporting flow calibration with their textured PEI sheet? I know the official guidance in their store is: “Automatic Calibration for Flow Rate is not recommended, as the LIDAR will have trouble correctly reading the print surface and Apr 24, 2023 · Flow Rate 1. Reddit iOS Reddit Android Reddit Premium About Reddit Advertise Blog Careers Press. 3 and 4 are identical and perfect. I have already tried using the flow dynamics calibration setting as well as the flow rate calibration setting, and both have not affected the issue in either a positive or negative way. That K value is assigned to the filament in question. Congratulations, you've now calibrated Flow Dynamics! Flow Rate - You go through a couple iterations. I would re-do the pressure advance calibration and then retry the flow rate calibration. On the A1, it measures the pressure in the nozzle with ( I believe ) an inductive ( Eddy current sensor ) to do flow rate calibration and active compensation. If I use the new calibration and save the results to the filament, do you need to run every print's dynamic flow calibration? Flow Dynamics calibration — no info on acceleration. Leave auto bed level on. 03 . Almost immediately after i get a note to disregard their colleagues, i will not be getting a heatbed as I'm not happy with flow dynamics and to pack . At the end, you get a K value. 17. Does it just run the in the background or is there a menu for it when changing out filament? I see videos regarding the P1S manual calibration where it prints for the K value and texture smoothness. 2. 0. I have the same issue, I tried to calibrate white PLA basic from Bambu lab multiple times now. Bambu ABS filament Which in reality is under-extrusion. I try to reinstall the Bambuslicer and even try to install it on my other computer. Ever since I installed a . Then you want to do a Max Flow tuning (Orca Slicer has a good built in model for this) Reply. ” - (Probably someone at Bambu Labs) Can't fully answer your question since I don't know how the flow calibration of the lidar thingy works. Now with Bambu I'm using the integrated version in Bambu Lab. The one thing that the A1 has and the P1S doesn't. I think I exhausted all logical options that I could change in the slicer itself in order to maybe reduce flow rate during solid infill and top surface moves. The other small lines don't worry about, and when you print the plate just uncheck flow calibration and they won't print. It is not done at the start of prints, unlike Flow Dynamics. The print was good, only bambu studio stopped working. Flow Dynamic calibration. I have a P1S so I have to use the manual option. I ran an OrcaSlicer flow rate calibration, -10 gave me the best results, and if I follow the "tutorial" it has me doing math (FlowRatio_old* (100 + modifier)/100) But if you click on the -10 object, it tells you it printed at a 0. Introducing Bambu Lab A1 mini - A colorful The little flow calibration test with the LIDAR scan performed at the start of a print only checks Flow Dynamics, and it can silently fail - if it fails, it will not throw up an error, but instead fall back the either a generic default value or to a previously calibrated value, so good to have a previously calibrated value available as a fallback. The only failures that I’ve had have been with clear filament (to be expected) and with the PA auto calibration using a PEX plate. This ratio is normally stable and the default setting works well in Bambu Lab printers and official filaments as they were pre-calibrated and fine-tuned. So unfortunately, if you switch to a different brand or material, you need to change this manually so you need to keep a record of the different filaments written down somewhere. Orcaslicer and textured build plates kinda makes the Lidar useless Jan 6, 2024 · Yes I agree, it seems that it only does the flow dynamics for the first filament. 6 nozzle and the default 0. The flow dynamics calibration is no problem, but I'm doubting how to best to do the flow rate. Currently, the X1 calibrates flow “per print”. 0) Not sure what I'm doing wrong here, but I can't complete manual calibration using version 1. Personally, I'm leaning towards the +10 setting, which I find visually appealing. Jan 23, 2024 · Bambu Studio Auto Flow Dynamics Calibration Failure (v1. Temp tower, pressure advance pass 1 and 2, max flow, max flow with 5c temp bump. When I let the Lidar auto cal, it always over extrudes. Better to print some models and adjust based on results. have to occasionally redo to make button appear, even when calibration was good. 8. Then Flow Rate, then Pressure advance (Flow Dynamics/K factor). Then you choose your nozzle type, plate type, filament you are calibrating, and what method of calibration. Washed them all with warm soapy water. Also may have to adjust speeds or aux cooling to get it finely turned That 2nd max flow i did because depending on the flow rate you'll start pushing plastic out faster than the heater can keep up with. Thank you guys! I always thought it was saved for that slot or something. Just checking im used to saving my filament profiles on the X1C with names for Flow Dynamics. So you will have to do the manual flow calibration which is not too difficult. The calibration results have about 10% jitter in our test. The flow was similar in sub 10% difference. Orcaslicer let's you edit PA values for filaments profiles. 25 instead. I have tried multiple materials and brands, same issue. 16. There is not one single straight line here. Black lines bleed over, for lack of a better term, into the white line calibration. Greetings, Any time I reset my X1C the K values get reset to 0. Bambu Studio. I’ve had it do dynamic flow calibration at the start of a few of these, but haven’t done the manual calibration yet (though I did try it awhile back and set it to . “Remember we are going after total market domination. Hi, I have the P1S so the filament calibration is manual. 56, P1 Firmware 01. Do not change any settings, just pick off menu and hit print. Show off your prints, or ask a question. I am a bit confused when I'm trying to calibrate my filament. It’s worked for me with Bambu PC, ABS, ASA & PETG-CF, eSun PETG, and generic PLA. It said I should recalibrate so I ran the calibration on the printer which finished. I am confused on the new Flow Dynamics Calibration in Bambu Studio and how to use it. The calibration prints just fine, but then I can click on the "Next" button and N/A is shown for all of the progress information. So every time I turn my X1C on I need to select the PA Profile from the dropdown. I used the cool plate with the glue stick from bambu. I don't have wood filament but some of my eSUN filaments have like 0. 2. Again, some geometry is generated and as before, preview and print. I know the quality goes down with the larger nozzle sizes, but not sure if this is expected. Line Color Not Consistent During X1C Flow Dynamics Calibration. Flow rate came up to 0. Bambu Studio does not have that pressure advance option. 85 (under extrution), one time to 1. 4 mm nozzle K=. And then you I'm assuming you are using the Bambu slicer software. calibrate with printer specific tests / prints (Flow Dynamics and Flow Rate) if you're on X1C don't forget to use a smooth build plate to give the lidar best conditions possible. ( Edit) Printer self-calibration with the plate. When running a flow dynamic calibration, the color of the lines for the calibration are not consistent. It uses the flow dynamics value you assign under the Device tab and filament graphic. Most PLA is at 0. Bambu support is being useless as well. kolifer. Turn auto calibration off. 9. BUT - you must uncheck the Flow Calibration checkbox before you start printing. Your application may need a higher level of accuracy and/or your printer may behave Flow calibration no, not really. The edges of your part are most affected by a flow dynamics calibration. toddanglin November 21, 2022, 3:45am 1. Click on calibration once again, this time go to Flow Rate, and Pass 2. DOH! P1S! P1S is missing LiDAR, the main component in auto calibration. depending on printer, check the box for flow calibration. Usually it is 0. I'm now trying to run the Flow Dynamics and Flow Rate calibration but after I hit calibrate, it sends the print to the printer, starts printing the calibration, and the Bambu Studio screen for calibration shows N/A Layers: N/A and the "Next" button stays grayed Manual flow and PA calibration on Orcaslicer. 02 (tested with orca - it’s 0. None of these are very very smooth, and I got under extrusion around the numbers and next to the walls To me the smoothest is -5 but the under extrusion increase Any advice ? Thank you ! I'd give -5 a try, know this post is old - you can barely tell a difference in how close the lines are. 15. What i have already done: - Flow dynamics calibration. I’ve tried default profiles for filament and print profiles, no change. Some filament won’t handle the high speeds of the machine. PEX and smooth PEI have been fine for Hi, I'm looking for any information regarding the Active Flow Rate Compensation and Auto Flow Dynamics. I understand people do a manual calibration, record the k value, and put it in the system. 000 and I need to select them again. 9 No cooling for first 4 layers Some of the Flow Rate Calibration prints do not stick on the plate. ago. In the right most tab (calibration) choose flow dynamics. I just don’t find it necessary for Bambu filaments. Yeah, I'm one of them - you can't click 'next' on the flow or flow dynamics calibration, if there's a beta out for it, I may go check that and see if I can get it EDIT: Confirmed it resolves flow/flow dynamics calibration issue Here we discuss everything related to Bambu Lab 3D printers. I assume it may be 5000, because this is the default value for the outer walls on most presets, but again, that is just an assumption. comments sorted by Best Top New Controversial Q&A Add a Comment k factor 0. If I do NOT use this, does the printer fallback to what it has stored for the detected filament (if it has a Bambu rfid) and default (or manually entered) values for non Bambu filaments? Flow Rate (aka flow ratio) can be calibrated manually or automatically through the Calibration menu in Bambu Studio. I only have an option for Manual Calibration. volumetric speed for the slicer profile. We are still investigating the root cause. When I click, it just gets stuck on this page with no information, and the p1s didn't do anything just sit there :<. I've ran Flow Rate automatic calibration, aswell as Flow Dynamics automatic calibration using micro lidar. It works with Orca Slicer so I am currently using it for the calibration and then I enter the result into Bambu Studio. I'm unsure about the flow rate cards, I was able to do a flow dynamics calibration test, like you said, very buggy, it didn't the test in 7 minutes. Ive done both the pattern and the line calibration but when the print completes im not allowed to use the "next" button to input my value. 01, 0. 024 . 026. Printed on the textured PEI plate with Flow Dynamics Calibration turned off. Automatic mode: the user only needs to start the calibration, and the printer will return the calibration results to after the printing is finished. The Flow Rate Calibration is the calibration of the Filament Setting Flow Rate, which is just saved to the Bambu Studio User Preset filament setting. Attached are five images showcasing the current settings. - Clean the PIE sheet and using glue to get better adhesion. I’ve checked all screws on the extruder head are snug as well. Bambu Lab studio x1c Even scrolled down and it nowhere to be found. The "next" button stays greyed out, and so I'm unable to record the factor. Auto or manual. I apologize if there s already a post addressing this - I searched but did not find one. Save to a filament profile. Bambu calls pressure advance flow dynamics. For a regular filament, you usually won't need to perform a Flow Rate Calibration. print temp tower -- if the best segment is close to your current temp or spot on just set it there and go to step 4. Flow Rate Calibration measures the ratio of expected to actual extrusion volumes. Welcome to Bambu Lab! Here we discuss everything related to Bambu Lab 3D printers. Hey guys, I got a p1s on july and ever since i've been printing great, but now the first layer is doing under extrusions, and i can't figure it out what is wrong. My question is, now that I have the new calibrated values, do i leave the flow calibration off from now on when printing ? (for that filament specifically ofc) also, is it worth calibrating even bambu Filament calibration uses lidar. 9 flow rate (see picture). •. done, why waste time. The printer creates 3 lines with 0. Eventually you end up with a chosen value from all the iterations you did. It makes sense that the edges were not improved after doing a flow rate calibration. I had a discussion with a bambu engineer who explained that the LiDAR function in regards to the flow calibration is basically taking real time measurements for dynamic flow compensation and absolute flow compensation and using those values in place of what’s enabled on the filament profile. Looks like it's slower! Flow calibration prints at speed proportional to the print outer wall speed. IIRC PLA . I don't know which setting would be used if Its not very clear to me if the Flow Dynamics Calibration is for each filament or if its a global setting for the printer to be used for every filament. filaments the first time it switches to them, since it has to do a purge anyway when changing I bought new filament from my usual supplier and want to dial it to my new P1s. You can then choose manual or auto calibration (if you have an X1). 018 for me for all of my Polyterra and esun PLA+) and the printer defaults to that value anyway so even if it is not done at all it will make no difference as the default value is sensible. - Flow rate calibration. 0 on my P1S. So I would keep the same calibration for Esun PLA. - Clean up all the extruder. P1S calibration fail. Manual calibration is better anyway. This happens for both Flow Dynamics and Run a Flow Dynamics Calibration. I'm using PLA. edit: oof, from this forum post it seems like the flow calibration doesn't save back to the slicer or anything. mapvqswzzbkriyzcvldn
