Finally a firmware with input shaping that doesn't require a Pi or a Pad. How good is it?
*********UPDATE*********
The bug with Creality's TMC2208 stepper drivers and linear advance has actually been fixed and shouldn't be an issue anymore.
INSTRUCTIONS!
1. Find Marlin and Config files for your printer here: marlinfw.org/meta/download/
2. Open in VScode, you need PlatformIO IDE too. Details for that are here: marlinfw.org/docs/basics/inst...
3. Change whatever you need to change for your printer and turn off linear advance for the testing phase.
4. Uncomment input shaping for the x and y axes and make sure the shaping_menu is uncommented too so you can change things easily - applies to LCD12864 displays.
5. Build the firmware and flash your printer.
6. Print the ringing tower as your test model, available here: marlinfw.org/docs/gcode/M593....
Make sure your speeds and accelerations are high, if you're using classic jerk then they should be high too. When using Prusa Slicer make sure the machine limits are ignored or raise them appropriately. The gcode for running through varying frequencies can be found at the link above and can be added in Prusa slicer @ "Printer Settings" - "Custom G-code" - "Before layer change G-code"
7. Use a caliper to measure the height that corresponds to the least ringing for both axes. Add these to the TH3D calculator found here: www.th3dstudio.com/marlin-inp...
8. Change your input shaping frequencies via the menu, pronterface or firmware if using the menu make sure to save settings in the configuration menu, if using pronterface use an M500 command to save the settings.
9. When the correct frequencies have been added you can then choose the correct damping factor. This part was not mentioned on the section on Input Shaping on the Marlin website and I think this was because it might not require much alteration. We couldn't actually see much difference when we printed a test file at varying factors. However, if you want to be thorough you can do it. To do so, print the same ringing tower with the "Input Shaping Zeta Testing code" available here: github.com/MarlinFirmware/Mar...
10. Check which layers have the best performance and choose the correct damping factor from there, adding it like the frequencies via the menu, pronterface or in the firmware.
11. At this stage it is best to recalibrate linear advance at higher speeds.
12. That's it! Print at high speed and see what happens! Enjoy!

@@3DJake_Official No worries!~ It's good to be up-to-date I ended-up successfully compiling an MPC + Linear Advance firmware for my stock CR-10 v2 (board), and it's running smoothly. I tried compiling an Input Shaping firmware for the CR-10 v2 (board), and it wouldn't have it. It simply blue screened on boot. This was also the case even with MPC and Linear Advance disabled. After rolling-back and/or flashing to the aforementioned MPC + Linear Advance firmware, it went back to normal without any blue screens. I guess the MCU and/or RAM, etc of the CR-10 v2 (board) simply can't handle Input Shaping as is - so a mainboard upgrade is necessary nonetheless if you want MPC + Input Shaping + Linear Advance on Marlin firmware

Just a random tidbit: Tom Brazier basically single handedly wrote Input Shaping in Marlin. The same guy who also wrote MPC and invented the algorithm behind it, which is the drastically better alternative to PID tuning. On another note, I always found it funny how so many people praise Klipper and resonance compensation using an accelerometer, yet the results you'd get with both Marlin's input shaping and Klipper's manual resonance compensation are more than fine, so long as you have the time and patience required for it. On the other hand, the accelerometer route may seem like the magical easy solution, however that can also be quite a bit of work, from custom mounts to custom interference free cables, so you actually get good results via SPI. TL;DR: Input Shaping and Resonance Compensation can easily be done without an accelerometer, and I personally don't see the benefits of an accelerometer outweighing the manual method, at least not when done right.

@Freddy-cx5yn Жыл бұрын

I agree with you on the resonance part. Same if not easier to do it manual. But, using the graphs you get out of your accelerometer makes it much easier to troubleshoot where resonance and noise is coming from. Like a loose belt or screw etc, with manual mode it is harder to find out that you are not as high acceleration as it could be. With input shaping your graph helps you to see if there is something wrong and you should be able to go much higher

@RealDids Жыл бұрын

@@Freddy-cx5yn That's a very good point! I've yet to actually try the accelerometer route myself, but will soon enough. Didn't even consider the added benefits of visualizing the resonance but can definitely see that being useful, especially after initial manual calibration and when wanting to tune it to be as perfect as possible. Being able to tell if there's a mechanical fault is another thing I hadn't even considered, yet would personally highly benefit from that as well.

So far the best video that explains why Marlon and Stock Creality are a no-go in most cases. I'd love to see a dedicated video on what upgrades would be required to get the most out of clipper as well as some direct comparisons. I can upgrade my hot end to a Spider Pro or Sprite Pro, which would take care of the issues with melting enough plastic. I'm leery about replacing my 4.2.7 boards as I am not familiar with compiling and flashing Marlon, other than installing a bin file on a flash drive and turning on my printer. All the other steps are over my head, and I would want the option to just download the bin file and flash the board with a USB drive, no fancy USB to connector, raspberry pie or whatever.

I just stumbled onto your channel as i was researching input shaping. back in the late 70s I was working in CR Scanner R&D and trying to increase data accuracy with speed and acceleration compensation for vibration. We were slinging an X Ray tube back and forth and rotating it to boot. So now in retirement i print 1950s Model Train parts and new updates. What else. My 10 S Pro is V1 with a lot of mods. OK to the point can I get this MArlin Experimental code to run on my 10S Pro?? I am on the original Motherboard but use Pi to run Octoprint. As I expand my parts list and am not getting more requests for parts from other Hobbyist, I need to make more parts faster. Especially test parts where you need to print a part to final test every time. So ..... What would You Suggest I thought at first the Creality 4.2.7 would help but it seems NO! We need more processor speed, second processor or a second printer for small parts fast. Any suggestions to help get my 10S Pro up to speed. Mods today: Z axis timing belt, Garolite Bed, Micro Swiss Direct Drive & Hot End, BL Touch, Z axis Struts. I also have a Laptop PC to use and not opposed to update motherboard or User Interface if it can tie in and help the end result, Great prints as fast as possible. The option is $1,000 Bambu, right?

Ooooh! ok so you probably won't be able to run Marlin's input shaper on the original mainboard (I say probably because people have used marlin 2 firmware on 8-bit machines, unfortunately, I don't know much about that but there are videos on youtube about it). You could upgrade the mainboard or (and this might be the best solution for you), you could install Klipper on your Raspberry Pi. Klipper is another firmware that also uses Input Shaping. But this really depends on which Pi you have though because it won't work on earlier versions so you need at least a Pi 2 unless you want to scale back on Klipper features. There is info on the requirements on Klipper3D's website, check out the FAQ there. If you want to go the new mainboard route it is, unfortunately, a bit tricky because the CR-10S Pro's touchscreen is close to incompatible with every other board. There are workaround for this with a little extra wiring but it is a bit messy. I would really recommend the Klipper on the Pi option if possible but if you have other printers it might also be handy to get a Creality Sonic Pad which is basically a big touchscreen with Klipper and it is suitable for the CR-10S Pro. This is around €200 so it is probably the most expensive of the options but it can run 4 Creality printers simultaneously so a great investment if you have a few printers. All that said, using input shaping on a CR-10S Pro is no substitute for a CoreXY or Delta printer like the Bambulab, Voron or FLSUN printers. The Pro has a big bed to move so you definitely won't be able to get more than 200mm/s out of it, I expect less, 150mm/s most likely. Which is pretty low compared to the printer brands I mentioned above. Hope this helps though :)

It was one of the last one available. I really am not smart enough to use it full potential. Guess I will keep reading and learning.

Yeah that is a pity, the test isn't difficult but I get the Klipper spoiling :) Whether adxl support is possible on a regular mainboard is a good question, I would think probably not.....might be easier to run the accelerometer on a computer and input the results manually.

@Kalvinjj Жыл бұрын

Some main boards like the BTT Octopus ones have several UART ports so it can read the ADXL accelerometer data, also I²C (which the Klipper page advises against but who knows). That could make it possible on such a board, but for the ones that are already fully occupied with TFT LCDs and such it's likely not feasible. I would love this as an Octoprint plugin as well, would solve the issue of no ports on the board.

Didn't work for me other than printing out the ringing tower in vaze mode. I've compiled the latest Marlin for my Kingroon KP3S, everything else works as usual but once I try to enable input shaping with a frequency found (turned out to be 32 Hz) the benchy can't go pass the first layer. After some movements the steppers just stop. I think it's caused by short segments. Also if I enable IS on one axis only, then only one axis stops, the other one continues moving. After cancelling print, it can't even home because I suppose the drivers are locked into an error mode. Also tried the ringing tower in non-vaze mode, with two perimeters. It stops somewhere mid-process as well. Also tried turning on and off the S-curve accel, recompiling/reflashing, no difference regarding the "stop moving" behavior. With no IS enabled from gcode, however, everything works fine, LA works fine etc. Using on daily basis, just not enabling the IS.

Fake news at 2:02 - Input shaper, as Klipper offers it, does NOT cancel out vibrations. It filters out frequencies from the movements which cause resonances on the printer. How should it remove vibrations and move in the opposite directions to counter them? The accelerometer is usually not even connected while printing, it does not even know if a vibration occurs.

@prxrb Жыл бұрын

It "filters out frequencies" exactly by commanding opposite movements from the steppers. It doesn't need the accelerometer to be attached while doing this, because it has measured the fundamental frequencies of the system in advance. In the same way that a pendulum of a given length will always swing at a certain rate, the printer will oscillate at a certain rate. If you know what that rate is, you can anticipate it

Marlin = one variable needing to change in pins or boards or several others = 20+ minutes of compile and flashing. For it to possibly not work. From scratch setup of a totally new Printer to a totally new board without previous examples = days, Plural Klipper = EVERY change takes seconds, can be tested within seconds, and a new printer conversion with new mainboard without previous examples = 2-3 hours. I'll probably never go back to Marlin. Just based on the R and D speed differences.

The manual testing was the most time consuming by far which is a serious drawback but adding a new board, firmware modification and flashing took about 25 mins.
