The Ender 3 V3 KE desperately needed this upgrade!
Help support this channel! / needitmakeit
This is the 3rd video now on this printer, but in this video we come up with a working solution for the bed vibration issues we were having which produced print quality problems. Not all Ender 3 printers seemed to have this issue, but with the small rods and a little bit of time and wear this will become a problem on all printers and I thought it was a good idea to be prepared with a good solid solution that was easy to do for just about anyone.
**SPECIAL NOTE: This has only been tested on my printer, if your printer looks different or things don't fit as you expect, leave a comment and I'll work with you.
Hardware You'll need:
M3 x 12mm (4pcs) - For Front Adapter & Y Axis motor
M4 x 20mm (4pcs) - For Rear rail to base adapter
M3 x 8mm (16pcs) - For Plate Adapters to Carriages
M3 x 8mm (12pcs) - For Rails to Front/Rear Adapters
M3 x 4mm Heat-Set Brass (20pcs) - For All Adapter Plates
US Amazon Link for Linear Rails: (This link supports the channel)
amzn.to/4a5YP9w - You'll need 2 'C' Carriages per rail (4 carriages total)
Linear rail carriages can be purchased separately if you can't find the entire kit - Model # MGN12C-350mm
Aliexpress Link for Linear Rails: (This link supports the channel) - They don't have stock of the 350, you can buy 400 and cut it to size, hopefully stock comes back soon!

So glad the algorithm pointed me to your channel. Really like seeing your methodical approach to testing. It's very satisfying you use a range of manufacturing processes to suit the purpose. The amount of time you must put into making these videos with all the printing etc is mind boggling. Your content is very professional, informative and super helpful to a new KE owner like myself. Well done and thank you.

@heyitsdrew Месяц назад

DO NOT BUY BLACK LINEAR RAILS! They coat them in a rust protective coating (Cold Bluing), yes. BUT what some suppliers do is they take OLD or USED rails and give them this coating to hide it. So you end up with not straight, or poorly coated rails. What you *should* do is buy normal steel rails that **aren't** black because protecting them from rust is not needed since they are already always coated in oil (which protects them), SO you can either keep up with lubrication (to protect the rails from rusting) or you can buy cold bluing solution and do it yourself - Birchwood Casey Super Blue - it is cheap and easy and anyone can do it. Just clean the part well, make sure there's no oil, rub the part in the solution. rinse and repeat (if necessary).

After 100’s of hours researching I didn’t go in with a budget, but didn’t want to spend more than needed at this point with the understanding there would be some issues. If I enjoy it, and can be productive making blanks and test pieces for my side business I will gladly invest into upgrading the printer itself to something more high end in the future.

I was able to get my rails on sale at Aliexpress, but when I went back to look they were out of stock... Amazon.com seems to have them for the cheapest at the moment, but maybe there is another source. Mine weren't the best, the stock Creality one on the X axis was smoother and quieter, and looks better frankly with the black.

Printing at the front left corner is when the belts are at their shortest relative to the x, y stepper motors. Any angle made by the belt mounting points to the extruder carriage and the bed support will skew the print as well as any vibration or imperfections from the geared tooth drive or stepper motor.

Speed is limited by acceleration, and these are limited by flow. I value high consistant flow over speed because i mostly print functional parts. Squareness and tramming of X and Y axis is one of the most important things, and thats where the budget printers usually fail. I just got my CR-10 SE, the squareness of the X-axis is hard to measure because the frame is covered in plastic. The print bed was 1,3mm off, and when i tried to fix this the bed screw got stripped cause they used screws that were not up to spec. This is just me scratching the surface of the printer, who knows what else is there to find. The "QC pass-sticker" on the side is a sad joke, however its the hars reality. I admire your efforts with trying to get the printer usable, hats off to you good sir!

@stew675 4 месяца назад

Excellent work Mike on going above and beyond to do the work that, IMO, the Creality engineers should be doing prior to product release. It seems to me that the Creality production model needs to change, especially in the face of its competition nowadays that aren't cutting corners nearly as much. Sure, Creality's printers are cheap, but as another commenter points out, to actually get them to a point where they print as well as a competing product that costs a little more, you end up spending way more than that competing product. IMO, the marketplace is changing. More and more people are expecting something that isn't cutting corners straight out of the box. Creality needs to decide if it wants to be a maker of well designed printers for a low cost, or continue to product straight up bargain bin items that don't work as well as the competition out of the box.

@NeedItMakeIt 4 месяца назад

Thanks Stew! All of this seems so strange, from the extruder to the rails to the steel plate, what was going on? Was this a noob design? It reminds me of when I was working on our bit CNCs at work a few years ago, we had custom bits breaking constantly, they caused 2 fires as well, when I looked at the design, it was horrific, I worked on a new design with a different company, and we used traditional methods of router bit design, and guess what. Not only did the problem go away, we had better cuts, longer lasting cutters ... and not by a small margin, by a huge margin. No more fire hazard. When something is well designed, it's a beautiful thing. I think Creality can rise to the occasion, they just need to say goodbye to what worked for them a few years ago, maybe it's not so easy. I'd love to see a modular printer design, give me a printer that is build-to-mod, I want threaded holes everywhere! Whatever Creality comes out with next had better blow our socks off, they need to innovate and do things differently. Take everything that people want and find a way to get it into a printer with a ground up design. I always appreciate your insights!

@przemekkobel4874 4 месяца назад

So, no chopping of the printer base... nice. As you redesigned the base plate, it reminded me of something regarding bed warping. I noticed that the bed is perfectly flat when not tightened to the base plate, after mounting and leveling it gets warped a little, and situation gets worse after heating it. Obviously the problem originates from tensions and thermal expansion. So maybe instead of mounting bed directly to the base plate via screws, it would be better to put 4 mounting points on 4 mini linear rails oriented diagonally? They should be tight enough to avoid any slack, and they would keep the bed tension-free (i.e. flat), even when it grows because of thermal expansion. Or maybe I'm talking nonsense, and warping occurs anyway, because the heater PCB expands differently than the bed it is glued to...

@TonyGrant. 4 месяца назад

I have to say that although I have a bed slinger at the moment (it was given to me by a friend) I'm not remotely interested in getting another. I will (and have) make some upgrades to this one but when I replace it it will be with a core x-y. Regardless of any input shaping you will always have the variable of the weight of the print itself increasing as well as the height which will cause inaccurate calibration as the print develops as well as oscillation as it gets higher.

@_powerbeard 4 месяца назад

The petg problems may be due to lack of dimensional accuracy of the filament. I have had the exact problem and that was the cause.

@simonbyrne1182 4 месяца назад

I also found my Y-axis bearings to be sloppy. I've adjusted them as much as I can, using the play in the mounting screw holes, but I never imagined being able to swap them for linear rails. This is a brilliantly engineered upgrade which is also entirely reversable if needed. I bought my V3 KE after having many impressive prints off the Ender 3's we have at work and I must say I've largely been disappointed with the print quality I'm seeing from it. The wobbling of the gantry bothers me so I plan on tacking that at some point.

@NeedItMakeIt 4 месяца назад

Unfortunately it just isn't suitable for a printer with these kinds of speeds, the steel plate, the central bearings. It's all good, we'll get it where it needs to be, the next video is going to be pretty cool and I will have something coming out for the Z as well, but first we need to do something pretty cool in order to get something we can work with a little bit easier. Sorry for being cryptic, the video will be release this weekend coming, it should be cool!

@suivzmoi Месяц назад

please do input shaping modeling before and after modifications. this is something i've been having trouble finding on all the online reviews/videos about E3 V3 SE/KE: we actually don't know the accel limit of this printer vs the advertised 8000 . it is always important to quantify objectively before and after changes are made and IS modelling allows fast and repeatable measurements without having to rely on subjective prints. my assumption is that all these modifications may not actually show improvements at stock settings but may prove their value at higher accel--meaning they unlock potential but you have to print faster to see it. regarding the 0.5mm droop at front right bed attachment, i have a feeling that the base of the printer on which the rails are attached may not be flat. it is after all also a stamped piece. i noticed you checked for parallelism of the rails in Z plane but not for parallelism to the Y plane. the front side of right rail may itself be 0.5mm lower than the rest of the rail plane. assuming a 150mm separation in the rails a 0.5mm droop is something like 0.2deg which is within precision thresholds of a cheap spirit level + eyeball and definitely detectible with a digital one. if the rails are misaligned in Y plane this will actually transfer flexing forces through the rail adapters/rail/rail carriage and into the stamped metal base. the base should flex the most but i think the printed adapters may also suffer from premature maintenance required. if the rails are misaligned in Y, the 0.5mm shim should be under the rail rather than above it.

First off, thanks for the amazing content and tutorials! I have followed 2 of your other videos and created all of the attachment points on the base of my Ender 3 V3 KE and also printed and installed the support arms for the tower. Now I'm attempting to do this upgrade(linear rails), however I'm having a problem printing the front and rear rail attachment plates. The hotbed adapters printed fine but the front and rear plates are giving me fits. I first tried ABS and towards the middle to upper end of the print they end up looking like soft half melted chocolate. Kind of wavy and the very top starts to curl a bit. So I tried PETG and that was even worse. Now I will say that I am a novice when it comes to 3D printing but I've been doing a lot of research on correct hotbed and nozzle temps for different filaments. I just can't seem to get these right. Any suggestions would be greatly appreciated. Thanks! Al

I have some Y axis location bias when setting the probe to nozzle z offset. Basically the offset is different at the front of the bed and the rear of the bed. I read that it could be from a twisted Y rod and a linear rail would help. Could you do the "Location Bias Check" from the Klipper docs please? Doing it just at the middle back and middle rear is enough. The difference should be lower than 0.025mm.

@NeedItMakeIt 4 месяца назад

Thanks! I think it could have been even better if I had used ABS or PC for the parts, but I didn't have enough of that in-house since I mainly print with PETG. The weight reduction amounted to just under 400g, but we added a small amount more friction with the linear rails, they are running nice and smooth now, at first they were a little bit stiff, especially one side. I'm working on a PC bed that anyone can do as long as there is enough interest, I also want to learn a bit more about the factors involved, expansion of the aluminum heat bed above it etc.

@waggy401 4 месяца назад

@@NeedItMakeItI'm interested. I have a KE and recently installed silicone spacers to get the bed more level. Mostly I had already sanded the originals, then realized that the gantry was leaning back a couple degrees. After correcting that, the plastic spacers were way off so I replaced them.

@geoffvanwagner655 2 месяца назад

so here is my uneducated take on these printers, i have a ke and in the terms of is it moving to fast for nice clean prints? yeah most likely. what i use my ke for though is for larger projects like helmets or armor pieces that i will be painting or adding things like damage scars. I think the KE stock or even with your upgrades is solid for doing just that. but if you want full on detail then you really need to just slow down the speed. its like that age old saying, you can have it done fast or you can have it done right.

I feel like it would have been a lot less work to modify the linear rod setup, possibly putting in another set of berings (like you did with the rails), and maybe even just replacing the ones that were there with ones that weren't so loose (if you couldn't adjust the ones that were there of course.. seems kind of strange to not be able to 🤔 ). This is definitely a very robust alternative though, and I do agree that it's a bit ridiculous to make something try to move so much mass around so quickly.. but then again, any of the printers are kind of limited by the ability of the material to liquefy and solidify in terms of speed, so why the printers are the only things getting the speed focus is kind of beyond me 🤷🏿‍♀️

@NeedItMakeIt 4 месяца назад

I see that the newer Ender 3 V3 (Metal frame) has larger dia. rods, and I would assume that it's to avoid this problem. My printer being new and already having the be vibrating needed a solution. I covered in the prev. video that the correct size of rods with a pre-load would be fine for this printer. I just figured it be better to have an option for long-term and there is one linear rail option out there but it uses only centrally mounted carriages, so we're back to the teeter totter effect. If they went with rods and somehow were able to run them out further, we could have bearing blocks spaced out further as well and it would be more stable, but they've crammed it all in there to look good I suppose.

Cool I will, it would work in combo with this upgrade, but I need to add a little more clearance because the PC or maybe ABS plate would need to be thicker, too bad we didn't think of this earlier. I may also try an aluminum version at 4mm thick which should be around 1/3 of the steel plate and it should be stiff enough as well. I'd like to see if I can have a company CNC machine it so it has everything integrated into one.

@@TinTalon The Bambu printers are very well designed, no doubt about that, they also use new tech to calibrate the filament, which helps even more to get good results and saves a lot of time, but you're right for entry level, you can start cheaper and upgrade and then when you're ready in a year or whenever you can sell that printer and upgrade again, there is a lot of development in 3D printing, by that time there will be a lot more options.

@kimmotoivanen 4 месяца назад

PC plate might be too flexible (esp. in Z direction) to work well, but let's see it tested :) Does Klipper have Z or weight compensation for IS frequency (Marlin FTM does, for the record)? Or maybe IS for Y should use wider shaper to cover the range from empty plate to full plate / high Z ? Overall, KE sounds like a good printer, until it's not. Likewise K1 sounds like a good printer, but VFA. K1C fixed that, but changed to different harder-to-get nozzle. If you have K1, how about a mod for smaller pulleys etc. to bring VFA on par with K1C? Maybe shorter stepper motors are not required 🤔 Bedslingers are perfect for slow big prints (plus and max variants) and moderate speed (still a lot faster than what we were used to in 2022 - thanks to Klipper and Marlin IS!) small prints. Core-XY seems to be the only way to go for impatient people with a bit more loose money or high requirements for print quality 😅

@NeedItMakeIt 4 месяца назад

It's certainly more flexible, I'd like to look at an aluminum version, and in each case I'd need to buy the accelerometer add-on to allow the resonance to be measured correctly. Right now it uses Klipper with hard-coded values and I could be wrong, but it should be measuring before for input shaping, but also while the print is occurring to adapt while the mass on the buildplate changes. They've made a cheap starter printer, but it's not as easily upgradable as the older gen with the extrusions, this would have been such an easy project if I didn't need to try and fit these parts to something that has such a strange shape. The newer metal frame Ender 3 V3 has a nice flat solid base, but it seems that they've replaced the small rods with larger 10mm, and maybe they'll be a better fit to avoid these issues. Having moved mainly to CoreXY myself, I see a pretty big benefit, mainly the enclosed print, but also that I can design and print something the same day, I can also take an order and ship it out the same day, which is pretty nice for everyone. It is a bit of an instant gratification, wait until the replicators come out.... I like your idea about the VFAs for the K1, there are probably a lot of people that could use an upgrade like this. Creality should provide one!

Hi! I think the PC could work well, I will see about making some tweaks to it and see if I can bring this to everyone to try themselves. If not from PC, maybe ABS as an alternative, not everyone has PC, but I'll try to make it so it's printable on any printer (may require at least a towel or two draped over your bed slinger). It seems a lot of people are interesting in the PC option, I will purchase the accelerometer for the printer and then we can get some measurements as well as compare the before and after, the Y axis vibrations are not so great and I wasn't running the printer at full speed, so we can do better. I will also look into an aluminum plate option, alum will cost more, but it should be stiffer and thinner as well. I say that other option for linear rails and I think they did a good job, but I was looking for something a little bit better that would last longer and keep that be as stable as possible no matter where we print the parts. I couldn't find any black rails at a good price unfortunately.... I looked for quite a while but I only saw one set which was far more expensive, so maybe we could use bluing instead?

Hi, good question! With ABS, you'd probably see about 0.25mm contraction over that distance, it's a good idea to account for it if you'd like a perfect fit. There is also some clearance in the holes, but if you want a bit more, you can use a 3.5mm bit and ream them a bit as well. I've found that that PETG-CF works great for these, they're quite stiff, but ABS would work really well also.

Hello, I finally received the linear rails from ali. Do you think it would be better to put them directly on the base plate via the created 3 mounting points for each (middle screw on the middle metal sheet). They should sufficiently strengthen the entire mounting plate. This would prevent any twisting. They would hold the bed firmly and perpendicular to the Z uprights. The thermal expansion of the mounting plate should then not have such an effect.

@NeedItMakeIt 3 месяца назад

If you can I think that's a great idea, I would have wanted to do this, I only avoided it to provide people with the simplest solution possible. Your idea is better I think. I guess my only small concern is that the base isn't flat and may pull the rails down to the position it would like them to be in.
