Pressure advance cura reddit Nozzle temperature 205, bed temperature 60. I changed my setup to direct drive for this exact reason. 038 made a huge difference. I believe the problem is rooted in using pressure advance on a large quantity of low quality bowden tube. Equalize filament flow. I needed glue to get it to stick, but once I did that its fine. 20+ Beginner here. I ran a distance tower and that seemed fine, but unsure on the speed still. 055 on the 400mm/s test, but thought I'd ask you for a sanity check. The seam is fundamentally caused by inaccurate extrusion near edges/turns where flow rate changes quickly. Linear advance can be configured in Cura. cfg file, on the pressure_advance variable. :( However, after switching to Klipper my Neo didn't suffer from a weird z-offset dementia and using Pressure Advance and Input Shaping isn't bad at all as well. Heavily modified/rewritten by Andrew Ellis. I am using a bowden setup, and form the nozzle to the extruder its 510 mm which are 51 cm for the formula. This adjusts the extruder flow based on upcoming gcode. Posted by u/Aromatic_Ad4107 - 2 votes and 10 comments The big reasons to upgrade to Klipper are resonance compensation and pressure advance. EDIT: wasn’t aware linear advanced isn’t enable in the stock Creality firmware. Higher pressure_advance_smooth_time will limit extruder acceleration (reduce chance of step skip) during pressure advance, but will make pressure advance less efficient. Tweaking Pressure Advance helped a lot, I think I decreased it slightly. pressure_advance = (vfr * bowden_length) / material_constant = (8. Changed it to 1. Edit for more information: I am using Cura slicer with the set up profile provided by kingroon, I have a 0. Theoretically retraction and I guess some pressure advance can be eaten up by play in couplers, oversized ID of the bowden tube, etc. Only available if it's included in your firmware. Someone recommended compression fittings to me for the bowden tube instead of push lock connectors to eliminate slop. [gcode_macro m900] default_parameter_k = 0 gcode = SET_PRESSURE_ADVANCE ADVANCE={K} I added the marketplace extension to Cura and put this macro into my printer. The first half includes an initial setup guide for getting klipper up and running on a pi alternative (inovato quadra) as the pressure advance and input shaping are necessary for better print quality. acceleration: up to 20000mm I’m currently tuning my printer and I have a lot of linear advance or too little, I don’t know, all I know is that the edges are bulging. that is expected at the top end of the test. Just watched a video about pressure advance, and this looks spot on with what he show cased in the video I would exhaust all possible cura settings first, Klipper can be a real task to install Reply reply More replies Hi everyone, I've just made the pressure advance with the klipper guide on my Ender 5 Plus. 5 mm. 0) and really makes the extruder quite noisy, actually the noise is the filament spool rocking back and forth. In my PETG prints I've noticed that the parts had the corners bulged (see photo), and I'm suspecting of a Pressure Advance (PA) too low. cfg and just make sure to adjust each time I switch filaments? The command is SET_PRESSURE_ADVANCE EXTRUDER={E} ADVANCE={K} I had the exact same problem when switching to a . org So basically what your pressure advance is on layer 0 and on the highest layer you are printing. Ellis' Pressure Advance / Linear Advance Calibration Tool Original Marlin calibration tool by Sineos. what were the test incraments? if you open the gcode file in notebook it will show you the test information. I’m assuming I could just save different printer configuration files but is there a way I can set it up like how I have linear advance values stored in each filament preset in Prussia Slicer? Not likely related to pressure advance. After assembly process, I just calibrated my rotation distance of the extruder, made a few calibration tests (temperature tower, retraction tower, flow, PID tuning for HE and HB, pressure advance) and it just works flawlessly! ive been tuning my retraction settings for three days. This is not an official Klipper support channel and poorly moderated so ymmv. Pressure advance is at 0. 122. The pressure advance calibration test of Orca printed successful with Klipper setting. Broken pressure advance will make the transition between fast to slower speed and vice versa to be broken like this. 20+ Then I'll often do: pressure_advance: 0. To really fix it you need Linear Advance in Marlin, or Pressure Advance in Klipper. Linear advance has been an option in Marlin for years, so you can certainly compile a version to include it. Pressure advance isn't actually calibrated in terms of pressure. 16 significantly reduced PA efficiency. I'm using a 0. Best way to know for sure is to lower it (I'd recommend starting at half and see what that gets you) and then reprinting the same model. Knowing you can print at 50mm/s @ 0. 075. Is it because the effects of pressure Advance are less at smaller nozzles? Trying to follow some tutorials on this and I'm running into trouble because I am new to both Klipper and Superslicer. 75). I have watched the pressure advance change in the console so I know the calibration command took, but the print corners look the same, bulging. 2 mm width if the nozzle drags it around. You should be able to get to zero stringing with PLA. 045 {% endif %} I will soon be adding a couple more “if / else” lines now that I am working with TPU and soon to try ABS as well. 'Once pressure advance is tuned in Klipper, it may still be useful to configure a small retract value in the slicer (eg, 0. Am I doing something wrong here? AFAIK, it functions as expected without issues since it's part of retraction and not pressure advance. Common names are: Pressure advance, Coast at end, extra restart length after retract. This is why Pressure/Linear Advance can help with corner bulging, extrusion even-ness, and even pull your retraction distances down to almost nothing. PETG will be somewhere between 1-2mm, with my highest value being only 2. Im running a modified Ender 3 S1 Pro with a . That is, the slic Chances are, your bowden can't cope with pressure advance but is fine with pressure relief. I've got slightly better print quality at 0. The old "lines" version of this tool has been deprecated. 4*51)/100 = 4. 025, as it is a direct drive extruder. PA just indirectly, approximately manipulates pressure at the nozzle by superimposing a time-dependent correction factor on commanded filament motion. Ballpark figures are 0. Check the bottom of this doc, PA makes no changes to XYZ. Pressure Advance (PA) is a factor that affects your retraction timing. So recalibrating PID tuning, Pressure Advance and Input shaper didn't make any noticeable difference. IMO, it better shows the PA effects and is less susceptible to first layer issues What settings do I have to set on Cura when using pressure advance? I have coasting and outer wall wype off. hehe, I'm using 0. Reply reply TheAZtech The Klipper Settings Plugin is compatible with the latest Cura 5. For the pressure advance stepping section, just follow the directions to use the recommended values for your extruder type. Think it might be worth it for prints that need precise sharp corners. 8mm nozzle. Current configuration: Ender 3 s1 Sprite pro extruder Silicone bed spacers Sonic pad with klipper Cura Pressure advance tower measurement: 14. I have found that for some reason (even though my rotation_distance is calibrated correctly) and I run a pretty low pressure advance of 0. Sounds like input shaping could mess with that, like you suggested. Not exactly. Hi folks! I just wanted to express my opinion about this printer. 06. The most common things that cause intermittent underextrusion like this are nozzle clogs, improperly set up Bowden fittings, and cracked/broken extruder arms. Unsure what cura’s jerk control does, but both marlin with junction deviation and klipper’s acceleration algorithm don’t use jerk values. I already calibrated my extruder rotation_distance (was 7. I wonder why Cura's unretract is cubed? 9. I only need to this once per filament/brand. Which gave me 8,92mm. It might be handy to make a wrapper so you you can use m900 to set pressure advance in klipper and use a cura plugin to set pressure advance per filament. I found mine around 0. Install them in Cura. 0 PRESSURE ADVANCE. Not discernibly better/worse with height. 040--LAST # A "high" PA number is 0. You will likely start seeing extruder step skipping before the needed pressure advance can be achieved. 18mm retractions after pressure advance was done. Anyways, I use cura as a slicer and I can’t find any setting for it, Thanks in advance! Welcome to the Ender 3 community, a specialized subreddit for all users of the Ender 3 3D printer. When I enabled linear advance I saw absolutely no change from the control print I made at K=0. Here, enthusiasts, hobbyists, and professionals gather to discuss, troubleshoot, and explore everything related to 3D printing with the Ender 3. E steps and flow both calibrated, I have entered the correct pressure advance tuning commands before printing as I can see in the terminal that the pressure advance value is being changed every layer. I have a . When you turn cura’s acceleration control off, klipper just uses max_accel in your config file. I didn't take a picture of the test print. LA would be the pedantically correct term for the algorithm both firmwares use. 3mm extra after travel. To the point: Linear advance is a pressure regulating setting. I use the Orce-Slicer 2. 188 [gcode_macro PRESSURE_ADVANCE_RESET] gcode: SET_PRESSURE_ADVANCE ADVANCE=0. > Klipper supports “Smooth Pressure Advance” - a mechanism to account for the effects of pressure within an extruder. I currently use SET_RETRACTION as a filament profile custom gcode along with "use firmware retraction", and wondered if "Enable Pressure Advance" was akin to the same thing. I successfully did both flow tests and now did a second round of the pressure advance test with similar results. 039 (Sprite direct drive extruder), I still have to turn the flow down to around 95%. so I guess I do the PA tuning on my 0. Just be aware that the value is changed by only a tiny amount (unless you don't use the recommended script), but I'd look at the slicer settings and check out what it says for z-seam alignment. The default klipper pressure advance tuning tower should be 20mm high. 4's and 0. It should look like this in your actual config. Depending on if you've got a direct extruder or a Bowden, you need to adjust it so when the printer expects the pressure to be cut to the nozzle, its been cut. Maybe it's just me with my set-up but Volumetric Slope combined with Pressure Advance is giving me the cleanest seams/lines/corners I've ever had, with a move like in the picture, typically even with PA this would result in the very end of the move having a kind of over-extruded look on the tip and maybe some slight under-extrusion in the taper You would know for sure by printing a cylinder at 40-50mm/s with Cura 4. I went through this a month or so ago and my pressure advance ended up being way too high. 005, and not 0. Cura uses 5 mm retraction as a default fro my printer. I add SET_PRESSURE_ADVANCE in my layer change macro in Cura or put it in the printer. 6mm nozzle from a 0. To only apply the macro's above, you should add or create a seperate filament profile for the filament you did your Pressure Advance tuning with. You need to multiply the measured distance by 0. 230 on pla and abs is fairly standard at 250. But with Klipper I'm still getting stringing with regular PLA @ 200c, 100mm speed 0. Hi all, I've been getting a lot of requests to post my setup guide for how I achieved a great looking benchy print from my N3Pro located here. Printing less than 150mms is great but going up to 200 mms causes pressure advance to get too aggressive using cura. I use pressure advance. The slicer normally doesn't set acceleration settings, unless you tell it to. You just might not be able to print as fast. 16 Layer height with an 0. Now, this assumes you already have Linear Advance set up and working without skipping steps. 2 and 1. But it's always good to test if you need it and I agree with @The-Scotsman_ that you should use ellis3dp's guide to calibrate your printer. I inspectes the GCode to make sure there were indeed Klipper commands, and they were. h files from Marlin's example Configurations folders, edit them to ensure you have the correct board type and therefore the correct CPU type and pin assignments, and a few other things, then compile. Turning off pressure advance allowed the print to complete. The only detail is that you'd need less retraction since the pressure in nozzle should be lower with PA. 28 at 9:45m mark She did use CORRECTION on her part and it should be pressure_advance: 0. 4318841), and now I'm calibrating PA. I see bulges on all of them. Every machine is difference, so, take your time and do yours thanks for your answer. You could also try Klipper - it has Pressure Advance (same thing) and has a bunch of other fancy things to make your prints better. 25mm on a stock creality mk8 end using a titanium heatbreak conversion. Use the calibration tools in Orca to fine tune temperatures, coolign, flow, pressure advance, max volumetric speed etc. the cube looks better with z Calibrate you volumetric flow rate and work from there. . Disable these options as they will interfere with Linear Advance. The Issue: While my printer can complete a print, the quality isn't what I would expect. With combing turned off my print time went up by 8 hours in retraction (as stated in cura after slicing). If you use firmware based retraction, which I believe klipper supports, then you can set the retraction parameters in the same code or you can continue to use the slicer settings Trying to set up the Pressure Advance but the Klipper website says to set layer height to 75% of nozzle diameter, and all print speeds to 100mm/s And the print fails at these settings. 8mm at 50mm/s. Which Slicer are you using? Can give some pointers in cura if needed. When I was using Marlin I was retracting 1. So I tried to look at where the walls start splitting. Slicing with 5. If this is the case, it could itself introduce a non-linearity to the pressure_advance value as extrusion speeds increase. Also, I have calibrated Pressure Advance for the PETG filament I'm using in the video (value of 0. 075 on the 200mm/s test, and 0. 2. Set up is Ender 3 v2 sonic pad dual z rods with sync belt Looks like it could be a pressure advance issue. Which is what it hits at 250mm/s im also running filaments temps higher than what you would for a slower speeds. It's a bit of a misnomer. 1 mm pressure advance lines. 125 {% else %} # PLA+ Settings SET_PRESSURE_ADVANCE ADVANCE=0. Check Klipper out on discord, discourse, or Klipper3d. I have not tested with Marlin. Hi friends using cura, I recently start using linear advance on my printer and the set up guide says you have to turn off combing for linear advance to function properly. The Slic3r devs admitted as much when they announced they were copying the Arachne code for their new release. With this in mind, I decided to follow (some of) the Ellis' Print Tuning Guide. Turning off the cooling fan also helped a little. new prints. In the process i managed to up the acceleration and print speed to 2500mm/s2 and 80mm/s respectively with out any quality loss. So I wanted to see what Anycubic Slicer has to say to the flavor and i was kind of shocked to see that the profile for the Pro is actually from the Kobra 2 regarding You should be able to define a macro to set the pressure advance value and then emit that in the filament specific code to set the filament specific pressure advance. Left cube is with pressure advance, right cube is without pressure advance. For example, when Cura introduced the Arachne engine it would reliably produce superior results to Slic3r. Basically, it makes sure that your extruded filament bead stays at a consistent width when sudden changes in speed or directions take place. I can use more pressure advance with the cooling fan turned off than with it on. 038 # pressure_advance: 0. 06 I mean, there are many users out there who get good prints with the stock setup, and I learned that most of the problems we encounter are actually kinda self-made. I'm on to pressure advance but I have a couple of questions about the calibration process that do not seem to be clear or I'm just not understanding them. A properly tuned printer running ABS or PLA needs practically no retraction at all. 284. I have my printer running at 150 mm/sec for infill speeds and 75 mm/sec for wall speed (cura default with 150 mm/sec overall print speed). In cura, change the size to 300x300x400. I have also done the max flow rate but on my old slow Ender 3 pro, I would never get close to it because the movement speeds are just too low. 0 and Extrudr ASA Now to my question: I have a Calibration Cube here and unfortunately I can't get any further with two artifacts: 1: Marked in green: There is a slight overshoot on the marked edges (and only on these). 92 has the ring). I also performed the pressure advance test cube, and changed the pressure advance value. 53, now is 7. Being on Klipper, I observe poor bridging quality -- even when using the experimental bridging settings (also tried 100%/0% coasting for briding, all other coasting is off because I use Pressure Advance ). Unless you set Linear Advance in Cura AS WELL as in the Firmware/EEPROM, Cura turns Linear Advance off in the Gcode. If I now add an M900 command to my printer start gcode, will it then read the LA setting I put in the slicer at the start of the print and set it for PA for that print? SET_PRESSURE_ADVANCE ADVANCE=0. In SuperSlicer I have my per-filament Pressure Advance under Start g-code (Filament Settings) like SET_PRESSURE_ADVANCE ADVANCE=0. It's worth experimenting with. I created a Cura plugin that gives full control over Klipper's Pressure Advance for individual line types and works with default Klipper settings. I did a couple of solid prints with my new Ender V3 Neo2 using Cura. White cube is cura and blue is prusa. There are a number of test prints for this calibration step. 55mm… Some slicers have options to control the nozzle pressure. The Ellis website does mention that Marlin firmware does not always have pressure advance enabled. /r/klippers -- a place to discuss all things related to the Klipper 3d Printer Firmware. This dynamically adjusts the speed of your print head instead of adjusting flowrate when changing line width. 1 or 0. 0. I realized I hadn't closed the loop on this. That is called pressure advance and not many people know what that means. Paint on Supports, variable layer heights (on curved objects), Mesh modifiers, etc And several more. 6's for PLA to start out with, and then PETG and the rest of the nozzles if I end up using Ive found that restarting klipper after every print is a temporary fix, but im not sure what would cause this in the first place. 25mm nozzle with an LGX extruder. There can be differences in both the pressure and the vibration depending on where the part of a letter is on a given layer. 050 and 1. 14-0. Just change the number. After following the Teaching Tech guide I chose a K value (0. 2mm I am getting klipper tuned on my Ender 3 with a micro swiss hot end. 2 instead. For everything else, you can just copy the settings you use in your slicer to the form here. first layer print speed first layer: between 20 and 50mm/s Normal: Between 100 and 250mm/s. Sliced with Cura, 80mm/s all walls, coasting turned off, 0. Steps-per-mm, flow, temperature, pressure advance and retract calibration are also done and set. I've used the The retraction settings are also based on my Klipper pressure advance settings at 0. I'm wondering if I should combine your two macros to look-up the right PA value as a function of both nozzle size and filament type. 02 Retraction is also the same @ . 08. It's still available here if you prefer it. 4 hardened steel nozzle. Speaking about Cura: it has some default values set for the given printer (which it uses to calculate the printing time) but they won't be written into G-code in any form. It doesn’t look like there are any differences between 0 mm and 0. Printed at 100mm/s with a 0. If I tune and set the pressure advance for each filament type colour, should I just be setting my flow to 100% in cura for all of them now? For example I used to run this black pla at 91% flow and a grey at 103%. Switching to orca was pretty painless in terms of UI, it feels like cura but better organized. Which is fine, at least you can get some benefit. 44mm layer height with 0. 5 for a Turn of coasting in cura, this approximates part of what pressure advance does. Following a recommendation on Reddit I wanted to try out Orca and I’m currently working my way through the calibration steps. 04 to 0. 000, this value is not acceptable. thanks for the silver :) people asking for this motivated me to fix the issue at the very end of the macro where it doesn't display the message properly, check the same link again for the update! the message shows at the beginning rather than when it should at the end, but at least you don't need to do as much thinking now After my post I tried the tuning tower to calibrate pressure advance, as described in the docs. As someone else said, in the infill the material can somewhat get away, but at the top and bottom it can only go to the outside, not inside, and so becomes even more messy. This reduces extruder “ooze” and improves the quality of print corners. Cura 4. I tried a temp tower and my best temperature was 205°C, which is also the minimum recommended for the eSun PLA+. And set my mark a little below that. The guy on the yt video has made a mistake at the end while calculating the Pressure Advance value. 04 for a voron/prusa style direct drive with a short captive PTFE tube and 0. I would agree that default 0. Try using the test proposed in the official documentation. Good for getting rid of those blobby corners on cubes. Edit: Oh, I misunderstood how fuzzy skin works. Also allows you to have 1 print profile per layer height/quality setting no matter the material used. Linear advance or pressure advance. on the video, she made mistake by putting pressure_advance: 0. Shall I maybe reset the pressure advance to a default value? So temp tower - flow rate - pressure advance (if you have a DD setup - don't bother if you have a bowden tube setup) - and then retraction if I see stringing. 04 nozzle I've run the pressure advance tower test multiple times as well as multiple retraction tower tests and my values at the moment are: Pressure advance: 0. and since the values of pressure advance can only be 0. But I think you're right, it's not the problem. On my DD printers I would go from between . In the photo you can see the difference (0. The print on the is after enabling print acceleration in Cura and setting it to 400. cfg file. Look online for the start and end G-code examples for the CR-10 smart pro. Have you setup pressure advance? If you have I can imagine that adversely affecting a fuzzy skin setting since its meant to prevent oozing. Have you tried upping temp by 10° step to see if it made any difference? In my experience if it is indeed pressure related issue, upping temp usually changes the defect shape. also with a 0. Please note that I am running this printer on Klipper firmware. 044 on my, but Its not perfect I have an Ender 3 v2 with direct drive Trianglelab BMG extruder and I'm struggling to get a good print of the pressure advance square tower. Things like setting your pressure advance by filament is a life saver as it can vary between materials. This means it will theoretically eliminate the need for any other pressure regulating setting, and if dialed in right, you should get almost perfect corners as well as almost no visible Z seam. during the video it looks as if the speed or distance was so high that it couldnt extrude. so the purge lines done exist, etc. I recently flashed the firmware on my Artillery Sidewinder X1 to enable linear advance. The consensus is that pressure advance does still help, but the Bowden tube limits the benefit. I put a comment just below the pressure advance settings: pressure_advance: 0. 1mm of filament to “early blobbing” during the process of If using marlin then make sure your linear advance is correct or if using Klipper pressure advance , these both also help to control filament flow and reduce oozing/stringing. Your standard calibration cube has letters which will change the test based on the shape of the letter (X, Y and Z printed on it). Gradual Flow is only for the transition between one speed and another. I calculated the pressure value and I obtain 0. If your firmware doesn't support Linear or Pressure advance, you can improve seams by reducing max X/Y acceleration. Nov 5, 2024 · I set up a pressure advance G code to run on my ender 3 v2. Here is my V3 SE Cura Profile *with input shaper + pressure advance. Filament is Eryone PLA. 4mm nozzle on a Cr10 V3. There are a few reasons to move away from Cura to Prusa Slicer: Decouple print setting from filament settings. 35mm is useful, but knowing that's 8mm3/s means you can set that as a flow cap in your slicer and generate max linear speed at any thickness, for example that's 89mm/s @ 0. But this affects print speed somewhat. These are based on a Wham Bam PEX build plate and the brass nozzle and heater block that comes with the BIQU H2 direct drive mounted on a modified Ender 5 Plus: Ellis Pressure Advance When running his gcode, can I dump this into Cura then go print? Printing the gcode by itself has the wrong temp, no brim, etc. Accelerations settings with pressure advance I recently installed klipper on my ender 3 and everything is going great. I’m almost 100% sure it’s pressure advance. You can turn up the first layer by 0. For example, if hypothetically one lost 0. When I switch to prusa slicer the issue is reduced but it’s still very visible. Save a file you try to print to disk and open the gcode file in a text editor you'll find M900 K0. 8mm nozzle on neptune 4 max. Ender 3 Pro running Klipper, slicer software is Cura. These features anticipate and/or adjust for problems that cause quality issues, like Over-extrusion, the whole thing looks a bit like one of those michelin figurines. My prints come out fine with the above notes. Edit1: Added Image, Speed, Temperature Executed Klipper commands for velocity limit and pressure advance tuning I'm using a standard Cura profile, with necessary changes made as per the documentation and adjustments for retraction distance due to the direct drive. 2 with the same settings vastly improved the print, greatly reduced the artifacts's presence. And this is what pressure advance is designed to fix. I have always redone my retraction tower tests after I dialed-in pressure advance. 00 in there put in by the Linear Advance plug-in. 17 value that is the default. The factor you put in is proportional to the pressure inside the nozzle for a given filament and temperature. It happens because the pressure in the nozzle stays the same when the print head stops to make the turn, so you get the same amount material continuing to come out despite the change in motion and direction. I'm confused by my results, because I don't see the variations in the print that I was expecting. Orca slicer has all of them. It will leave the nozzle with the correct pressure prior to starting. cfg? Do I comment out pressure_advance entirely, set it to zero, or what? Will SET_PRESSURE_ADVANCE overide any setting in printer. I have been trying to dial in my printer since I upgraded my Firmware and decided to move to Orca Slicer from Cura, I have gone through various calibration routines including Teaching Tech's and all of the other Orca Claibration tests and have the printer pretty well dialled in but I cannot get these Pressure Advance test to show any variation on the the prints. 0 and creates everything in a new Klipper Settings category with a number of new options. I will post the two pics. Those are the first three things I’d rule out. Jan 12, 2024 · A smaller pressure_advance_smooth_time could thus reduce the amount of filament lost due to “early blobbing”. For issues/bugs, contributions, and feature requests, please open a GitHub issue. Mine is input shaper and pressure advance tuned, i found the limit for my unit specifically is about 20 (ish) mm/s cubed. There should be almost no ooze, once the proper K-Factor is found. gcode: SET_PRESSURE_ADVANCE ADVANCE=0. 00. The Max Comb Distance with No Retract was at the default of 0. What I am unclear is what to set on ENABLE ACCELERATION CONTROL and Jerk settings? Also, wait until you get into the advanced features in PrusaSlicer (which mostly is included in SuperSlicer ), plus a few SuperSlicer features. every print needs slightly different settings. I have input shaper working and getting pressure advanced tuned. For one of our printers going from 0. 7 and seeing if you get blobs at random parts. You should look at Pressure Advance. Linear advance/pressure advance slows down the extruder towards the tail end, but the calculation is based on all the relevant factors. 041s. Based on Heimjoint's suggestion, I tried slicing it with Cura 5. I havent changed the pressure advance of . Question is what to do with the extruder settings in printer. Increasing the Flow by a few percent on the outer wall helped a little bit. Start G-Code (From Creality Print; Excludes M109): M220 S100 ;Reset Feedrate M221 S100 ;Reset Flowrate G28 ;Home G92 E0 ;Reset Extruder I recently flashed my CR10-V3 with Klipper, in order to use the pressure advance and input shaper features. Edit: I think Marlin calls it linear advance. Hi, I’m new to klipper and am trying to figure out if I need to tune pressure advance and input shaper to each different filament or not. Iirc, Klipper docs say to redo retraction tests after PA to stop this type of issue. It takes much more material to get up to proper extrusion pressure with a . Resonance compensation reduces or eliminates ringing (AKA ghosting) by calculating the resonant frequencies of the printer assembly and eliminating them by emitting a counter frequency - the same frequency just out of phase with the frame. Otherwise you'll over-extrude during slowdowns and under-extrude during speedups. What Pressure advance Stettings do you use? Standard is 0. For testing linear advance, a tower will work better than that calibration cube. Same gaps just before the corners. 25mm (slight retraction as per some guides on Google I'd like to avoid fw retraction for the moment) Retraction speed (cura): 45mm/s Switched to orca, now I still get them occasionally but it usually means I'm using too much pressure advance or my hotend temp is too high. Klipper’s implementation does not introduce instantaneous extruder speed changes, which improves overall stability and robustness. And pressure advance drastically changes the retraction requirements. 9mm retractions to around 0. With it, you disable coasting. 3mm layer height along with input shaper EI at 3000mm/s Acceleration. 04 is optimal for most printers. I remember seeing someone say that a setting in cura needs to be turned off when you set up pressure advance, but im not sure what that setting is or if its relevant info. Then I adjusted the pressure advance and came up with the print on the right. 92 but the edge doesn't looks good, so I decide to increase the value to 0. Put that value inside the printer. And somewhere around 0,045 in pressure advance. Also disable options like wipe while retract or combing. 5mm retraction, 205/50 temps, 100mm/s speed Should I just increase flow a bit even though I calculated it by following teachingtechs video? By printing the one wall cube and measuring thickness. This keeps the pressure constant in the nozzle and looks ahead to demand. Perhaps that value is better for pressure advance. 99 (by reobserve the test that's I made). Anycubic Mega S with Klipper; both Prusaslicer and Cura Sunlu PLA 215 and 55 degrees set everything to 100 mm/s except first layer; of course used the settings given in the Klipper manual for tuning pressure advance 3 mm with 25 mm/s I‘m still building my Klipper config and try to understand which settings may conflict with others.
