Klipper input shaping - A leap forward in high speed AND high quality 3D printing [Rat Rig part 4]

[@pkucmus]

If someone is new to Klipper (or RRF for that matter), please notice how Michael repeats "just save and restart" - there's no firmware flashing to change those rather complex settings.

[@Apophis-en9pi]

Good to know. I'm switching to Klipper to try this. Never used it before.

[@kendokaaa]

That's probably enough to get me to eventually switch to Klipper

[@Dr3DPrint]

Hi, Pawel... I love Klipper, but have my Lerdge here too... heheheheheh Neither save and restart... Just mark in th screen and it's working!

Michael, Please keep up the Klipper content, and, "Dare" I say it, go DEEPER down the rabbit hole. I believe it to be a GREAT firmware, it's biggest hurdle to overcome being that tipping point of acceptance where there are so many tutorials, that one can't help but find the explanation/tutorial/inspiration/guidance one needs. ....

[@minidotrar878]

@@TeachingTech If your going with a bed slinger, you should try a core XZ config.

[@michaelplaczek9385]

Using an accelerometer and input shaping is really cool

[@victortitov1740]

Yes. And the next step should probably be active oscillation suppression right during the printing by constantly monitoring the acceleration.

[@TeachingTech]

I see this being used to detect skipped steps too. Like the Prusa method but better.

[@cda32]

Using I2C with long wires you need to add a stronger pull up on the remote end to account for the increased capacitance of the transmission line. The Adafruit ADXL board has a 10K pull up, changing that to a 4k7 will give you more reliable signal. Also make sure you keep them far away or shielded from the high current lines for heaters and steppers.

[@TeachingTech]

Thanks for the tips. It's been reliable since I ran the ADXL loom separately to the rest, you are spot on.

[@pinaz993]

@@TeachingTech You can also try twisting positive negative pairs together to reduce crosstalk. That's what's done on Cat5e and up.

[@star_burp]

I struggled with this for a while. Don’t be like me and re-crimp, re-wire, re-solder; try a short cable with 3v & Ground first. If it works now, cut off any excess wire then maybe swap out the resistor 😁

I also tried Klipper with a CoreXY printer, and I fell in love with it! The first love was OctoPrint, and this second one is much more deeper. :) It is like starting to race with a nice street car. With shiny multi tone metallic paint, leather seats, quality car audio, beautiful rims, all the fancy things. Then you reach the limits of that car, and build a dedicated race car. Shaving off all the fancy things, and you only keep the necessary ones, but use the best of those. This is how you find a whole new level of racing. Klipper with Fluidd is the dedicated, purposely built race car of 3D printer world. :)

You are a best source what ever i tend to do. a year ago i bought ender 3 pro, and i have set up the visual studio and compiled my custom setup and upgraded to direct drive and bltouch, while changing my driverboard to skr mini e3 with octoprint. it has been really easy to learn all of this in a year. Now I'm dreaming of updating to clipper and making voron 2.4 for larger and faster printer. The old prints abs and tpu without problems, but many prints do not fit into ender and it is still slow. But thanks to you, everything has been like playing with legos.

Instead using the macros to turn on and off the led you can use the switch in the fans and output section. If you add the pwm section in the [output_pin] you can also change the brightness with a slider in the same fluidd section
