    I had silicon mounts on an Ender 3 for about 8 months and I had not problems at all but then my BL Touch mesh was not working I tried everything before I realised the gantry on the right hand side had dropped and changed the level above the BL Touch's tolerance, once that was addressed I had no further issues and the silicon mounts have been on for a total of 23 months now and never need adjusting as they hold perfect tension.
    I would advise any viewers that are having levelling issues to check the level of their gantry to the frame and not to the bed, there are many videos showing how to level the gantry correctly on YT
    This is a great video, showing the actual data for each spring is extremely informative.

    As always, thank you for taking a scientific approach to your investigations. Always helpful. I've found the yellow springs to last for years. Once set, and using BLtouch, I never have to adjust them. But if I had to do it over again and change out the factory springs, I would go with the silicon mounts.

    I replaced the stock springs with the yellow springs after printing over 100 hours, hoping the leveling issues would disappear (adjusting before every print, sometimes taking up to 30 minutes!). Reduced but still had to re-level after every 3 or 4 prints (verses after each one). The amount was less but still needed to be done. Then I saw a video about putting a lock nut (with nylon inner "seal") on the screws to prevent them from turning when turning the large adjustment wheels. What?!? I did experiment and found the screws (at least mine) did spin a bit. I installed the locknuts and at the same time replaced the yellow springs with silicone spacers (mine are black, don't know if there is a color code for compression resistance). I appreciate your video as it logically and empirically showed what I suspected to be true - thank you for all the time spent reassembling your printer so I didn't have to do it again! What a pain...
    The Ender 3V2 has held "level" (stayed trammed?) for a month without needing adjusting (being paranoid I was checking it every day that I started a print but didn't touch the leveling knobs. Prints were ok but I like to tinker so I added a BL touch, mainly for my sons so they wouldn't need to mess with the adjustments. So far I am happy with the modifications. Next one will be adding Octoprint! Or upgrading to the Jyers firmware. Or a new controller board... {sigh} As long as it is printing well, I don't really have an excuse that satisfies my wife so this configuration will have to remain until after Christmas {grin}.

      When you added the touch, am I right in assuming you still have to adjust the z offset?
      From what I can understand, you add the silicone spacers, tighten down to virtually tightest it will go, manual level and then do a z offset to compensate form the probe? (I've got the CR touch installed and assuming it's the same principle)

  • @MisterkeTube
    @MisterkeTube 3 ปีที่แล้ว +18

    The problem with the original springs is that they can move sideways while being compressed. When adding your second weight this was clearly visible for the original springs. This sideways motion allows for extra inaccuracy and additional modes of vibration.

  • @TK4619
    @TK4619 ปีที่แล้ว +7

    I have been using the silicone for about a year now and find a much more stable bed after many prints, I also installed a small m4 nuts on the screws on the bottom of the bed before installing the silicone to keep the screws from spinning loose, That way the only moving part is the adjustment wheel on the bottom. I did many test on both of my ender 3's and the nuts do make a big difference.

    at 14:26 -- the pockets in the silicone also allow for a nut to lock the countersunk bolt to the bed. If the friction of the countersink cone is less than the friction of the threads on the M4, then the head and bolt will spin rather than the leveling knob moving up or down the both..

    Fully coil binding the bed springs and move the endstop switch to match (may need a new endstop mount) then level the bed, will lower the centre of gravity for the build plate and lower ringing/ghosting. Having the bed levelled at the default height allows way too much bed movement.

    Excellent video. I’m a 48 year old 3d printer rookie. I’m on my 4-5th month and just got my 3rd printer. Started with Ender 3 to Ender 3 S1 to K1C. Though a printing rookie, I’m not without mechanical experience.
    What I’ve come to feel is that the bed springs have almost nothing to do with bed leveling and more importantly are under the build surface to protect the tool head from excessive Z offset. There are no provisions in the control boards(that I’ve seen) to detect a current spike from a motor to trip an anti overload switch. Cheaper protection suspend the build surface on a cushion.
    It’s like those Rings the “Pro” “Wrestlers” use to get all sweaty with one another. When they land on someone having just left the top rope, if the mat was statically mounted there would be a lot of fatalities.

    To answer your question, after more than a year after switching to silicone mounts, I didn't had any issues. I don't know if they become more stiff or if they deformed because I simply installed them and never touched them since. I realized that I didn't even leveled my bed after. Using Bl Touch and a glass bed. But to be honest I never needed to force anything while removing my prints, thanks to some magigoo.

  • @Kalvinjj
    @Kalvinjj 3 ปีที่แล้ว +9

    Nice test, I've used the yellow ones on my bed before, but when I upgraded to a bigger bed I went with the silicone columns, albeit mine are the clear white ones. I did notice they're far stiffer than the yellow springs, but I mostly chose them because I thought they might have a better sideways stiffness based on them having a lot bigger surface area than the springs. They've been on the bed and printing for now... just a day, but let's see their durability on heat.
    One thing I would like to add, that you kinda saw on the tests, is that the tensile strength graph shown is valid mostly just for traction, albeit with steel the linear line should be similar, a compression graph would not show a rupture line for example, it just goes up and up and deforms more and more (since it won't ever snap, just become wider and shorter instead). A spring, if designed correctly, should never have permanent deformation under compression (which is the bed leveling springs), as it would, like you found out, bottom out way before the material itself has problems, and by then if you manage to make the material deform by compression then you're probably using some absurd alloy bolts and destroying everything in the way too. What can cause weird things when plotting a graph is if it starts crossing the coils, like would happen with the default Ender springs. The columns whoever might have permanent deformation problems, as they can't bottom out, but, as they're so much stiffer already then you're probably running into the same thing as bottoming out the metal springs and crushing them. The heat and long therm part tho is interesting, as polymers react way differently.

I just wanted something with low thermal conductivity as to not cause the bed frame to work as a heatsink, the silicone mounts just made sense to me, I don't think the lack of elasticity is going to cause any issues.

    Thanks for a great comparison. The silicon posts are good for auto-leveling set ups while providing a very slight give to the bed in case the nozzle scrapes. As for manual levelling, I've never had problems with the "weak" stock springs. Tighten the wheels to fully compress all the springs. Adjust Z-stop to trigger on the highest point of the bed - move the around while turning the Z rod to find this. Perform your bed tramming routine by only loosening the wheels. This will ensure maximum spring compression while keeping the wheels tight.

  • @yertelt5570
    @yertelt5570 7 หลายเดือนก่อน

    If you are just hobby printing wait until the bed cools to remove your print, once the bed cools the parts slide right off. If you're in a hurry you can spray some alcohol around the perimeter of the part to cool the bed faster and you can use the excess to clean the bed. Anything that keeps you from yanking on the bed will help reduce bed leveling. Lock nuts on the adjusting wheels will help too. If you have ABL or manual mesh you can replace the springs with a solid spacer. This can be tricky to level initially, you'll have to add and remove shims/washers to get the bed level to start, but once you get the bed level it generally doesn't move, any slight changes can be compensated by the ABL or checking your manual mesh occasionally and adjusting if necessary. Disclaimer: I have not personally tried the solid spacer method, I am currently using the upgraded yellow springs, but from what I've seen online people who have tried it like it. Most new printers that come from the factory with an ABL probe installed also come with solid spacers installed from the factory.

    I have found this video now. I have used all three and I have actually found the yellow springs were the best on my Ender 5 (original model).
    I found the factory silver springs were way to weak, it would move too much. The silicon blocks, on the other hand, were too rigid and made it virtually impossible to level the bed as moving one corner even 0.1mm would upset all the other corners. The yellow springs are stable, don't move during prints, but flexible enough that leveling the bed is easy to complete. I print on the original Ender bed, PEI bed and glass and a BL Touch. I find the yellow springs best.

    Wouldn't metal spacers be better, assuming they are safe to use and don't cause other issues.

    @henricoderre 3 ปีที่แล้ว +1

    Hi Igor. I recently changed my springs for the silicone mounts. I am not a mechanical engineer, so forgive me if I am not able to back up my understanding of this system with proof or data. As I understand it, if the bed is level, then you don't actually need a BLTouch to level the bed. The BLTouch does nothing to level the bed. That's why you have to level it yourself before you can use an auto bed-levelling device. The BLTouch only compensates for bed surface irregularities by adjusting the height of the nozzle, and to function properly it relies on a mesh pattern it creates then stores either on the SD card or in the EEPROM. If the printer bed is level after installing the silicone mounts, it should remain relatively level as long as the mounts do not compress too much more. The BLTouch will then help compensate for the height differences between nozzle and bed, which is affected by the deformation of the build surface. Thanks for this video. I appreciate the scientific approach. It helps me to better understand 3D printers and how these work.

    • @MyTechFun

    Good video. Your graph shows that the factory springs compressed at a higher rate above 10.6kg load. That explains why I was having such a hard time adjusting the spring in the back left corner, because it has the extra 2mm base from the cable guide and would compress greater than the other springs. A small change in the knob would result in a bigger compression change. One thing to note, you tested the compression of the springs but did not show if they retained any deformity from the compression. A properly designed spring will not deform when compressed. If you had measured the compression of the springs after multiple and prolonged compressions, you would likely find that they retained the same compression force, although I am aware we are talking about Chinesium springs and they may have cut some corners on the design. I think the silicone ones are more stable and less susceptible to vibration and heat deformation than the metal springs. I just installed the silicone spacers today and printed a 3d-benchy. It came out a little smoother than with the original Ender 3 Pro springs.

      One of the stock yellow (ish) springs on my Ender 5+ didn't just deform it broke! when I took them off I could see they were very different from the yellow springs I bought for my other printers, when I bent the spring metal it bent and then clean snapped and you can see micro holes in the metal when under my cellphone camera and zoomed in

    What about orizontal dilatation of the heat plate?
    Springs permit the holes to move a bit, silicone bushings compress too much obliging the bed to dilatate in vertical creating a dome. So the nozzle become more closed to the bed in centre and distant in corners.

    Do you have pictures of the ringing before and after each of the modification of springs? I would say that with the factory springs you should see a lot of ghosting/ringing and with the silicones they should be greatly reduced. A side by side photo would be cool.

    Thank you for the info. I was wondering if there may be any heat transfer from the bed to the yellow springs that may decay their elasticity. If there is a teflon or carbon fiber washer to negate that but over time being compressed it will affect them. Good thing they are cheap for now.

      You need 4 metal spacers, but if they are not flexible at all, it is hard to have the bed in flat and leveled (parallel with moving path of the nozzle). You need minimal elasticity to adjust this.

  • @mikeneron
    @mikeneron 3 ปีที่แล้ว +2

    Excellent video. I had replaced the original springs with the yellow ones on all 3 printers at one point. I bought 3 sets of the silicone spacers awhile back, but only installed them on the Ender-3. One issue I had when installing them was my bed wasn't trammed very well to the gantry so had to really tighten down the one side to get it close enough and then have the BL Touch do the rest. I haven't had to re-level even after months. But that goes for the other 2 printers with the yellow springs as well, so I'm not sure how much of a difference the silicone spacers would really make in the long run. I'll probably still eventually install them on all 3 printers though since I have them.
    To take it a step further, what if the spacers were made out of steel and then had zero deformation? If your bed and gantry are trammed really well, then could see this working, but if your printer is like mine then it would be too far out of "level" for the BL Touch to compensate so I think having some play as you get with the yellow springs is probably the way to go.

    • @dalem04
      @dalem04 3 ปีที่แล้ว +1

      Solid spacers are available, but the problem is unless they're manufactured right and very precisely, your bed is going to end up out of tram and every print will have to be compensated for. I got some and I couldn't get the bed close enough to level for my satisfaction.

    If there is a BL touch, why can't we just put metal spacers in place and double lock nut the adjustment wheels when we get a manual level? That would permanently set the level and the software could compensate? Get rid of the spring function completely because it is unecessary?

    • @MyTechFun
      @MyTechFun  2 ปีที่แล้ว

      Yes, a lot of printers which have factory installed BL Touch have fixed bed. If you can fix all 4 positions to be flat (in 1 plane), then yes. But it bay be hard, especially because of back left one. The plane position is important, to avoid warping of the plate.

  • @klave8511
    @klave8511 3 ปีที่แล้ว +1

    I see the bottom line as:- if you treat your printer bed like a workbench, buy stiffer springs and/or a bed levelling sensor.
    Comments suggest some ringing is more likely with more compliant springs, maybe just the frequency of ringing but my E3 is slow so if I see ringing I might consider stiffer springs.

    Running Klipper with resonance compensation means I don't care all that much about vibration dampening. But the silicone mounts have another killer advantage - a tiny bit of extra usable Z height. Unless you're cranking the strong springs way, way down, the silicone mounts are shorter.

    I love how your graph shows how much dampening affect the silicone has compared to the springs. However, running klipper with input shaping, the resonances are going to much more offset from the bed to the nozzle than with springs, where the linear reliable movement creates desirable oscillations in my opinion for klipper specifically. What's your opinion on that?

    My 2 cents worth on leveling an Anet8 Plus. I removed the glass top, took out the 4 bolts for the heatbed. I then bolted the Anet8 Plus on a piece of plywood. I put items under the plywood to level the 3D printer. I leveled the X gantry to the bed frame in both directions. This is where things get strange.....After doing the familiar exercise of moving the tip around the bed and homing Z axis a few times I noticed when homing the left Z motor makes a grind noise and lowers the left Z axis a bit. Disable the motors and twist the right Z axis to level it up again. I spent 5 days with this problem until I printed a new Z axis stop that mounts on the left side and then removed the left and right spiral rods ,re-set the set screws into the rods and leveled them. I replaced the springs with rubber ones. After many times homing the Z axis the level of the gantry has stayed level. I printed a test for checking the levelness...perfect, time will tell. But checking the gantry being level on all prints will be a priority for me.
