@Kregary42 Год назад

Thank you for your work, your tutorials are really great! I have very little knowledge about programming and I got an error after I did all your shown steps. Klipper says "Unknown pin chip name "adxl"". The solution for this was that I just have to rename the [mcu ADXL] into [mcu adxl]. I just want to pass it to others in case someone had the same problem. By the way, I used an RP2040 zero, it is a little bit smaller that the RPi Pico. It seems to be almost identical to the RPi Pico. No pins have to be changed in the programming. Happy printing! 😜

@RetiredRhetoricalWarhorse Год назад

The crux of this matter is that it is so simple once you've done it that explaining it seems redundant... Thanks for making this a complete tutorial, I got it working thanks to you. Sometimes I feel like the 3D printing community doesn't expect the less electronics literate to want to participate as well :D.

@jose91cr 2 года назад

Your channel is amazing, man! I've watched a few videos already and they have all been great. Thank you for all the work you put into them

@substratum3d Год назад

This is awesome. It's simpler than I was thinking it would be. I just built my first voron 2.4 and have really grown to like klipper as I set it up. I'm planning on switching over my other printers to klipper over time and with this I'll be able to replace some of my full blown pi's with zero w's. Thanks man and keep the great videos coming.

@DustinGorman Год назад

Hey thanks Nero. I really appreciate the video. I appreciate all the hard work you do bringing us this type of content. It's super helpful! I currently only have 1 voron, a 0.1, still in pieces in it's box. In a couple months I'll be getting a 2.4 350mm, then I'm done getting FDM printers. I'll have 10 at that point. I really like this idea. I've tossed up the idea of converting all of my Prusa machines over to Klipper, but still weighing the pros and cons. Anyhow, thanks again man, you're awesome!

@GregsMakerCorner 2 года назад

Such a great idea! I love the portability of it. Thanks for sharing the video, definitely going to give this a shot.

@JakusJacobsen Год назад

Thanks for doing this. It made it super easy to install on configure the Fysetc portable input shaper by just doing it along with you, with some of the steps already done for me. I can recommend the Fysetc kit so far, really good.

@CanuckCreator 2 года назад

Quick additional TIp, instead of using something like winSCP to get the klipper.uf2 file off the RPI run cp out/klipper.uf2 ../klipper_config/klipper.uf2 after creating the firmware flash file, this will copy the file to the same director as your printer.cfg file and you can just download it from the klipper interface webpage

@glabifrons 2 года назад

You'll get a similar error the first time you run the command as you received at 11:23 due to a bug introduced in Klipper several months back. It always fails on the first try and works after that. I found the exact commit that caused the problem, but as far as I know, they still haven't fixed it. Nice video, by the way... you went into even more detail than I did on my write-up. I tried to link to it, but even mentioning the site name gets my post auto-deleted. Just google "Raspberry Pi Pico as a secondary MCU for resonance testing working!". There's good discussion in there about how Klipper identifies which group of SPI pins are in use, among other things. If you use a ribbon cable instead, you can use 3D printed snap-together case that allows you to press the button as needed. It's linked in the above mentioned thread.

@Tuxedo2680 11 месяцев назад

Thanks Nero for pointing me to the workaround I needed to get input shaper to work on my BTT-CB1 equipped Trident. I can now confirm that it works perfectly. The Pi Pico dongle is a convenience if you have a Rpi in your printer but it is a necessity if you have a CB1.

@davethetaswegian 2 года назад

Great stuff, I was just about to wire up an ADXL to the RP 3B of a printer I am upgrading. But I have some Pi Picos in a draw somewhere, so definitely going to use this method instead. Thanks.

@P1-Engineering 2 года назад

Great stuff! I use the Zero 2W on all my printers with a screen which goes directly on the GPIO pins. So for input shaper I always had to disassemble the casing, remove screen etc etc. Now I have a USB hub to the Zero 2W and connect the Pico!.

@yaVDRgda 2 года назад

No need to use another computer and winscp or any other copy method. Your Raspberry Pi is running a very sophisticated operating system, named Linux, that can flash the pico without any help. Just hold the boot button on the pico and connect it to the RPi. Now mount the pico by using 'sudo mount /dev/sda1 /mnt'. Next copy the flash file: 'sudo cp ~/klipper/out/klipper.uf2 /mnt/' and umount the pico 'sudo umount /mnt'. Ready!

@philr6829 2 года назад

Another well done video! If you are looking for ideas: I just recently switched my case light from the MCU to a WEMOS D1 Mini with WLED. One quick section added to moonraker config file and now Macros can send commands to WLED. WLED has a web interface so you can set any number of presets for klipper to call up. Can have multiple strings (like case lights and SB) and control all from the WEMOS. Very simple install and significant increase in options/ability.

@fkncobra 2 года назад

Great video as always. Setting up klipper for the first time on my very first printer, with a thin client (rpi zero not available everywhere where I resides) this gives me hope to try rpi pico as secondary mcu on usb with adxl345.

@starkastic 2 года назад

Using the old ethernet cable was also a great tip. I have a ton of ethernet cable with broken connectors that I could easily cut up and make use of.

@dev-debug Год назад

Was looking for how to do this so thanks for the concise video ! My only suggested change would be to get an ethernet cable with stranded wire and lop the ends off. That would work well with a Pico breakout boards (about $7 USD) then you can use feruls into screw terminals. Eventually one of the the solid wires will break. Going to order a Pico and breakout board today, total will be about $16 US. I already have dual panel mounted USB jacks inside the enclosure so this will make life to much easier. I wish I could do it with an Arduino since I am adding one for a more flexible fan control system for the electronics enlclosure. Currently fan control only works if the mainboard is always powered on but the Pi and power supplies need to run non stop creating some heat. Con with Arduino is you need lofix level shifters to protect the Pi when using the bigger Arduino boards.

So I managed to get my klipper up and running on a desktop with 2 printers. I have noticed that if I include the adxl.cfg in my printer.cfg for both printers one of them does not want to connect to klipper. I'm assuming it cannot run like that on both printers. So far I'll add the include adxl.cfg as I need to but I thought I'd throw that tip out there in case someone needed it. Thanks again for the video. It's been very helpful diving into a very deep subject and not get too lost.

@@vignesh_waranYes, you can even use VirtualBox to run FluiddPi or Mainsail. Over all RPi Zero W is powerful enough to run printer with configured shaper but in stock it's not strong enough to do shaper calibration and calculation process, I've seen people overclock Zero W and it helps to solve this issue.

Nero, thank you for your videos. I just stumbled across them but after watching, you gave me the needed push to install klipper. I have an Anycubic Vyper, pi4, Miuzei display which occupies the gpio pins and want to install two ADXL’s. My question is this, since I do not want to mess with the gpio on the pi4, could I use two pi picos, with an ADXL on each, then plug these into the pi4? Overkill yes, but I want to permanently install the ADXL’s and not have the aggravation of moving them around. I have a second Vyper I will be installing klipper on, as well as a Kobra Max. Still looking at options for the max.

@bellers85 2 года назад

Your videos are always very informative and thanks for creating them. What advantages does this give you over extending the raspberry pi's gpios and plugging the adxl directly in? I'm not hating, just want to understand.

@LightCarver 2 года назад

I think the biggest advantage comes in when you have Pi versions without the pins on some of your machines. Even if you have all full size Pi with header pins, you would have to make an extension for every one to achieve the same convenience.

@justinsfunthings8263 Год назад

he mentioned this already at the beginning of the video. he wants portability, the ability to move the device to other printers easily, and without having to go back under the printer.

@dodong_daniel 2 года назад

Because the INT1 and 2 are not used, you can solder 1 with a pin and leave 2 empty. Then if you fill the location for INT1 in the Dupont connector, it's impossible to connect the Dupont connector the wrong way around.

@eclypse3d Год назад

On mine I had one pin initially that did not solder well enough so when I pushed on the DuPont connector it pushed the ping up every so slightly and separated the solder joint from the pcb just a hair. I pulled it back down till the pin started to pull through the hole just till it was just about flush, resoldered it and as I was soldering I pushed the pin back through it to make the connection. After that everything was fine, but I did experience what Ludwig below did and noted that it failed on my second printer on the first try, I redid the query a second time and everything was fine. =)
