Heres my set-up: E3V2 with stock hotend, 0. Reply reply And, for direct drive printers, a retraction distance between 1. That is direct drive BMG clone though and 4mm is a lot for DD. On Direct drive systems the extruder sits very close to the nozzle and it requires much less effort on retractions. They way 99% 3D printer lovers use for “direct drive” is technically wrong or, at least, incorrect. Thanks 60. 5), and retraction speed went down from 50mm/s to 30mm/s. Too slow and pressure doesn't get relieved in time and hotend oozes. I use 40mm/s. Esteps on both are about 205 and 134 respectively. 5mm DD retraction or around 2. For direct drive extruders paired with the Mosquito® series of hotends, we recommend setting your retraction to the same distance as the diameter of the nozzle you are printing with. Where the geared and ungeared extruder differ in this regard: you'll probably have to decrease retraction speed on the BMG since the motor has to turn faster in order to achieve the same speed. Open comment sort options Also if you do add retraction, which on a DD you totally can, make sure your retraction speed is really low. 30mm/sec retraction speed. Retraction settings are in the Travel section. so that your extrusion is consistent, since the bowden drive has the inherent "lag time" in building up and dropping pressure in the bowden tube as filament is extruded and retracted. With Dual-Drive hobbed gears for maximum contact and power, and hardened steel drive gears for processing abrasive Retraction is the key to reducing stringing. 6mm and retract speed @ 100mm/s I tried to use a retraction tower for a new filament material using retraction speed as height modifier, and while doing so, I noticed that the maximum retraction speed at the top of the tower (80 mm/sec) never gets Well, I was pretty stunned when I was able to get virtually no stringing at 0. i have the same thing but i managed to solve this problem by replacing the high acceleration type stepper motor nema 17 23mm 1A or nema 17 25mm because the ender 3 stock stepper motor type is high torque low rpm not suitable for extruders with gear ratios like bmg. I use 0. I first print a retraction test with pressure advance disabled. Metal single gear extruders should be directly swappable but I’d personally get a dual geared extruder with a 3:1 ratio like BMG. I installed a BMG clone, set my esteps, it's printing nicely. 2mm retraction minimum travel 10 retraction count Personally I have used the speed drive (with a clone BMG + stock hotend) and the Afterburner (with dragon hotend)- both with a slim nema 17 stepper motor. 8 mm retraction (middle) at virtually any speed between 10 mm/s and 60 mm/s (left). Thanks for the advice! Direct drive retractions should be tiny but with my BMG direct drive conversion I have retractions set to 1. 4 to 1. You should use 415 for the beginning, do a e-step calibration and then use these new numbers. Can’t remember the exact numbers but I’ll post when I can. Bondtech recommends not to use more than 25 mm/s in retraction speed. For a BMG DD I start around 1mm retraction and 25mms speed and calibrate from there. You can go more on the distance - think I've seen someone mention around 1. Used to struggle with retraction as too much causes extruder to grind filament and too little oozes everywhere. The main settings you need to worry about are Retraction Distance and Retraction Speed. On my direct drive Orbiter extruder / Dragon hotend combination, I use 1. The only thing you need is to set the BMG steps per mm, I set those at 415 steps/mm. 5 and 2. My most recent test had distance around 6ish+- and speed around 140ish+-, and by turning extrusion up Direct drive isn't so much about speed but accuracy, you have to push the filament less distance so have more control over the extruded material, faster retraction rates due to less distance required to retract. “Mini Direct Drive” Admittedly, you got it wrong when it comes to what “direct drive” really means. 6mm for PETG for example. Hey! Yes that’s correct, I lowered my temp by exactly 6 degrees cos that’s what worked for me based on the temp tower I tested on. f So I just upgraded my Ender 3 to direct drive (bmg and e3dv6 clone, full metal heatbreak). To decrease the probability of heat creep and nasty For retraction speed do you have a bench mark? I’m currently at 30mm/s. 2nd line is Travel Speed. 8 is pretty good, I would bump up the speed a bit to maybe around the 30 mark. Retraction to 0. @Adamfilip I use bondtech BMG direct extruder with a hot end that has a 1 mm nozzle. Reply reply Using Bowden retraction values on a direct drive would lead to this kind of behavior. It Mine is an ender 3 with BMG extruder set up as a direct drive. I myself run a bmg-clone from trianglelabs as direct drive, and am happy with it. I retuned the hotend PID after doing so. Even you can good result with ender 3 or other Cura 6. 4 + tube length[mm] x 0. I've done 7 tests and they all look identical. Are you running the extruder in stealthchop mode? If so, perhaps your retraction speed is crossing the hybrid threshold, prompting the driver to switch to spreadcycle which generally sounds aweful. To keep things this way, we finance it through advertising, ad-free @saffi said in Retraction for E3D Volcano and Direct Bondtech BMG: I ran something like 0. typically, the e-steps of an BMG (clones) are somewhere between 415 and 425 (while the default extruder is at 93ish). The BMG® works in both bowden and direct driven applications. If you already have a bi-metal heatbreak or similar, or you're just set on a new extruder, get that BMG extruder, I've read good things. 6 and 0. 5. The extruder is mounted directly above the print head, and has a bowden tube about 45mm long going into the hot end. Direct Extruder (or Direct Feed, to I am already down at 20 mm/s retraction speed with 2. The first line is (retraction amount) @ (retraction speed). I just have the frame of an Aquila. 6mm and retract speed @ 100mm/s I've read in many articles that a direct drive extruder should need between 1-3mm of retraction, however, my printer (trianglelab bmg clone + dragon hotend in direct drive) just needs ~0. I've been doing incremental mods with my Ender 3 V2, and I moved to direct drive yesterday. My trianglelab bmg came in a few days ago giving me the chance to fully test it out. 5 retraction and speed 40mm does the job for me. I've only tweaked distance. The retraction length and speed is actually pretty normal for a V6, anything above 1mm is too much. retraction speed : 35 mm/s; retraction distance (bowden) : ~5 mm (0. With pressure advance tuned, my current retraction setting is . The PTFE tube length is only 37mm! Assembly of the BMG E3D V6 Direct-Drive for Ender 3.

Learn the best Ender 3 retraction settings! All3DP; All3DP Pro; Printables Basics Buyer's Guides News. Yes it’s quite low for distance due to the fact that the BMG grips the filament well so retraction wise it doesn’t really skip a step. html#esteps. 3 or so. 2 mm layer height. When calibrating travel Really flexible stuff will always have some stringing. You probably don't want to go that fast though if your extruder uses a single extruder gear with a spring tensioner like the stock extruder. I swapped out PTFE tubing for Capricorn, and retraction with 1. Controversial. 5mm; Height: Your maximum retraction length will be (height - 1) * step. Calibrate E-steps any time you switch your extruder and then do a calibration test with a retraction tower to find optimal settings The tradeoff is that you have to spend a lot more time screwing around with getting proper retraction, coasting, etc. 0mm Retraction Speed (I may lower this to 45mm) 0. My HEVO is running on bondtech BMG direct drive on a E3D v6 clone and S3D my extruder multiplier is 1. What were your retraction speeds on these prints? I'm at 3mm and 35m/s but I'm afraid that speed may be a little low. After I installed a bi-metal heatbreak, retraction distance halved (5 down to 2. I found out that it's e steps related, high values like 415 makes it loud, with spreadcycle doubling down on it. I have now converted to a direct drive BMG extruder with just 2mm extaction and it works very well. You can also give inTinker a try. (height: 11 when using a step of 0. At higher speeds, you might want to print a replacement for the BMG with tighter filament path, or a modified extruder that uses the BMG parts. High speed, high quality printing is best done with linear advance, which cannot be utilized to the fullest with bowden, and favor direct drive. One uses a BMG, the other MicroSwiss. Petg I increase the retraction distance but lower speed and tpu I reduce both retraction and speed. I've read 4mm to 7mm, but that seems quite high. 60. Printed Direct Drive Mod Retraction/Oozing Settings I recently printed THIS Changing retraction speed from 25mm/s to 70mm/s Lowering the temperature (for PLA) down to 190 (I'm able to still get material to flow with the temperature as low as 160/170, but I don't think temperatures that low is reliable, nor does it help oozing that much) Ender 3 with BMG direct drive and Microswiss hotend.

According to an Overture paper that I received with my filament, "direct-drive should have a Retraction Distance of no more than 1mm and a Retraction Speed of 35mm/s. I followed the advice of a user to bump up my temps 15C (205C -> 215C) to fix under extrusion, and reduce my retraction from 6mm to 0. PA is Calibrated and is 0. 5mm at 80mm per second. ESun PETG. We've had similar questions about bmg's on a discord I'm member of, and after users settled on 25 mm/s retraction speed the noise got away. There is a remix of the speed drive mod that allows for a pancake stepper (no reduction in build volume) and it’s less weight. For the micro Swiss, don’t go above 4mm retraction. 5mm and speed of 35mm/s. 7mm to avoid jams however, now im getting stringing again, so im wondering what are some good retraction and temp settings that work for a good starting With bowden a retraction of 6mm with speed 35 worked fine for me. 2mm retraction distance 25 mm/s speed 1. I have a V6 but Bowden, and use 4mm@25mm/s. My HEVO is running on bondtech BMG direct drive on a E3D v6 clone and S3D Interesting, maybe I should turn up the retraction While direct drive extruders indeed require retraction settings to be configured differently compared to Bowden extruders, the differences are pretty straightforward and do not involve any technical complexity that would make the configuration process challenging. What other issues are you having? BMG direct drive with original E3D V6 hotend, dual Z, SKR mini e3 v3, tft35 e3 v3, hotbed and hotend mosfets. 8mm!!?! 80mm/s retraction speed?! Both are far too high. I was originally using the BMG as a bowden extruder, but get much better results with direct Are you in Direct Drive (Motor/BMG attached to hotend carriage) or bowden where the motor/BMG are attached where the stock extruder was? Pancake motor would help for mass reduction on the hotend if running direct drivebut you get less torque with one. Direct drive only needs a retraction of between 0. I’m using Cura 4. This thread has the info and a link to photos I took of the printed test pattern. Good: I don't have stringing issues. Anyway, to find any setting, you can always search for it. As @Phaedrux says, the max speed should be set for the maximum travel speed (e. 0? The latest version is 5. For your Anycubic Kobra needs Your retract noises are because the retraction speed is too fast.

(Bowden setup + bmg extruder) And increse retraction speed a little. 5mm to 2mm Retraction-Speed went from 60mm/s to 10mm/s The first 1,000 people to use this link will get a 1 month free trial of Skillshare: https://skl. I haven’t bothered taking the time to dial this in. Can anyone tell me what I should change in Cura apart from retraction and speed? I know that someone mentioned to disable coasting and something else I think but I'm not sure. I usually use 1. 2 mm retraction distance. I actually have a V6 and BMG (both are clones) setup with the BMG directly connected to the V6 and dual 5015 fans. The advice from the Triangle Labs page is as follows: Retraction speed over 80MM/S, retraction length 2. Retraction speed refers to the rate at which the extruder motor drives back the filament. Inexpensive high quality stepper drivers and improved firmware kinematics and features have allowed for higher quality, high speed prints even with the added weight of direct drive Example 1, Example 2. The published Steps Per MM are extremely accurate and should need no changes when used as direct drive. The direct extruder mod with BMG dual drive and MGN12 linear guide. 87A Peak = 0. any ideas why? So, I've found PLA does just fine with faster retraction speed.

Open comment sort options. If some problems still persist, isolate the source by doing, one at a time, the following checks: Direct Drive? E-steps value? BMG: yes Starter values to calibrate retraction- BMG direct drive . If I were to do it again I’d go for a bondtech LGX. Much shorter retraction distances and reduced I have a Ender 3 Pro with a Dotbit BMG dual drive clone and SKR mini e3-dip. There'd be no reason to go anywhere near 20mm in a retraction test for direct drive. : Retraction-Distance went from 6. I'm just moving one thing at a time so as not to get too overwhelmed. This hot end is better on a direct drive tbh (I use it on a direct drive with 1mm), because you’ll generally use short retractions on those. Y axis belt broke, replaced with new one and added belt tensioners to y and x axis. Anyway, I doubt you will be able to print at 100 mm/s even with 0. I wonder if they meant 0. Direct drive: 0. In essence, correctly configuring retraction settings for a dir Hello @Gear, on my Kossel mini BMG bowden I am using accel 3000, max speed 1800, jerk 1200, current 1400.

Retraction: 1 mm/s Speed: 27 mm/s E-steps: 407 mm/s (I originally measured 406. 5 then they likely need to be dropped down to about a . The retraction speed is 35mm/s. Even though experimentation will always yield the best results due to differences in hardware, here are the retraction settings of our recommendation that can act as a starting point for printing PLA successfully: Retraction Not true I have ender 6 bowden setup all metal hotend i changed retraction 10mm to 2. 2mm and a tiney ammount extra restart distance. Edit: However mounting the extruder over the hotend (direct drive style) reduces the retractions and stringing. I no longer have an Aquila though. Of course now my prints look like crap and everything needs to be recalibrated. 7 board, bltouch, marlin 2 bugfix and direct drive and can only get good results when using retraction settings of 6. Reply reply Need help finding right retraction setings for my ender 3 pro bmg direct drive 6. Retraction is at 0. Seems like 5. 6mm nozzle and BMG extruder upvote To use the DDX remember it is a Direct Drive eXtruder with a gear reduction of 3:1. Open comment sort options If going from bowden to direct drive, your retraction is going to need to be a lot lower, and your temps are probably going to change a bit as well. Old. 4 mm nozzle, set the retraction distance to 0. 4 mm nozzle, Genuine BMG extruder mounted as a direct drive, Minion D hot end cooling with 4010 blower. Hi there i haver 1 ender 3 v2 with klipper clone v6 bmg direct drive and when print from this site is very nit with almost no retraction when print with the same setting from prusa or cura is all messy with a lof of strings. I upgraded my Voxelab Aquila to a (clone) BMG dual gear extruder, on a Unitak3D direct-drive bracket. Direct drive allows lower retraction. In direct-drive setups, the distance between the extruder and the hotend is so short that the filament can’t really compress or bend. Q&A. Changing driver current doesn't help, nor reducing retraction speed by 5mm/s increments. 2 Print jerk: 10 Print Acceleration: 300 Wall Acceleration: 300 Initial speed: 10m/s Print speed: 25m/s Retraction distance: 5mm Retraction speed: 25m/s Absolutely no stringing so far and I am currently print an octopus and I 60. 6mm nozzle and have no idea where to start testing retraction settings. • • Edited . 4mm, which I would think is too low to make any difference. You’ll need to reprint a new adapter though as the outlet is much further away from the motor than stock. Retractions can be very short and the stepper motor will need to move 3 times faster. You should be doing tests and calibrating for a much lower retraction distance. I have found that since turning on pressure advance, the thing tends to over extrude and I have to set the extrusion multiplier to 85% to get normally Lower retraction. You can also adjust it in increments of 0. sh/crosslink04211GIVEAWAY IS OVERCongratulations to Dan H. 0 on PLA and 0. 5mm , retraction speed to 25mm and no stringing prints way better than stock hotend All metal hot ends cause stringing and clogging with big retractions The Bondtech BMG® extruder combines high performance and resolution with low weight. Update 2 will be directed to the retraction. 6mm and retract speed @ 100mm/s Hi all, recently added a speedDrive version for the BMG extruder. 5 mm retractions with 50 mm speed,bmg extruder. 5mm to 2mm. I will calibrate pressure advance now. Start with 1mm, only go up to an absolute max of 2mm if required. So a direct drive is probably much Typically Ive found higher retraction distances and speeds work well. You will notice that all of the fastest printers have a direct drive It's said what matters more is the retraction speed rather than length. I think the micro Swiss is one of the less good options, the setup is heavy and offers no more torque than the stock extruder. Together with our proven and highly celebrated Dual-Drive technology you can expect problem free material feeding. the super tiny one with the assumption that the motor is at a 45 degree angle is pretty great, if you've got a pancake or round motor Wrong, less retraction = faster print times = less stringing = shorter filament path = more consistent printability of flexible's I found no degradation in print quality going from bowden to direct drive if you need speed its still an upgrade you will just need the better tuning from klipper Retraction Speed Tower Experiment upvotes Petg retraction settings with a micro Swiss direct drive upvote [Help Needed] Consistent extrusion issue after 0. The bmg is a beast, never had an issue with underextrusion, clogs, jams etc. I have tested it on a reaction speed of 70mm/s, the retraction length is 5-6mm The only settings you will change in firmware is reverse e0 stepper direction and set e steps at 415 and in pronterface or another program send g code to calculate esteps closer, and in your slicer your retraction distance and speed will need to be done and other minor tuning to slicer Replace the stock extruder, with direct drive this can be a little tricky. 3rd line is (hotend temperature in C). It was because my retraction BMG definitely can print it okay, at slow speeds. Speed is 50mm/s Reply reply throwmeawayafterthat Printer Configuration. It assured steady extruder pressure for tough and flex filaments. Since I can't reduce esteps, nor retraction speed, I think I will have to switch to direct drive, even if I didn't really want to. I'm using 0. 6mm and retract speed @ 100mm/s Thanks for the write up, this is the path I'm going down. If some problems still persist, isolate the source by doing, one at a time, the following checks: A BMG is not a direct drive it is still a 3:1 gear reduction, so that might be the first part to look at. 8mm distance and 90mm/s speed for pla and abs. 1mm) You will rarely need more than this, but it is possible with some high flow hotends and setups. It also might reduce the need for retractions, which would definitely solve some issues, but it doesn't solve the problem of extruding TPU good enough to print in the first place @deckingman said in Extruder acceleration/jerk and tuning:.
