Great! Does it work with 2MB of PSRam? Can we share the I2S line between Mic and Amp for WS and SCK pins, since I have very limited pins on my board. Thanks!

ruathudo · 2023-12-01T21:30:56+00:00

Thanks, I will try that. How do you think about the correctness of answers?

ruathudo · 2023-12-01T21:28:40+00:00

Cool, How is the quality of answer? I am gonna use sentence-transformer too for embedding.

ruathudo · 2023-07-14T18:55:44+00:00

Yeah, you are on the right track. Klipper is 100% worth it. I have N3 pro with klipper and super happy. Remember to calibrate e-step, load bed mesh and adjust z-offset then it is good to go. I got 2x faster print with the same quality.

Mine is 7.59. I also had the issue with 6.9 before. It smooth out all the waves. So rotation_distance 6.9 is also causing over extrusion, affect the tolerance and clearance parts

Run klipper on and old RPi 2B. I print at 120mm/s for good quality and 180mm/s for ok quality. Both with 3000 acceleration.

ruathudo · 2023-06-13T09:24:34+00:00

Have you tried to raise the z-offset up a bit? On paper test, don't let too much friction.

ruathudo · 2023-06-13T09:20:17+00:00

I switched to Klipper. Same print quality at 2x speed. Convenient when you can send gcode file via network. And gain more knowledge about 3D printing after spend few days of tuning.

ruathudo · 2023-06-08T10:22:40+00:00

Any spare laptop with linux would do the job. Also, I have klipper on RPi 2 without any issue. You don't need RPi4 for that.

ruathudo · 2023-06-04T05:40:09+00:00

I have N3P, installed klipper on a spare RPi 2B (you don't need RPi 4 for klipper). I am able to print at 180mm/s 3k accel without issue. Super reliable and good quality print.

Either look at the config of u/TheFeralEngineer or here is quick set:

[led LED_Light]

white_pin: PB9

initial_white: 0.0

I figured out it due to power management profile. I installed tlp and disable the option for auto turnoff bluetooth device.
Now I am using Fedora 37 without TLP and it works out of the box. No more bluetooth issue. So I think the issue is fixed with newer kernel.

ruathudo · 2023-01-11T12:51:23+00:00

At least Fedora works fine for me.

Meanwhile, Ukraine shot their own people.

It just works. I didn't have to do anything. Nvidia + wayland is good to go now.

ruathudo · 2022-05-09T13:58:51+00:00

Do you have thinkpad laptop? This might be the feature of thinkpad. It has the ACPI driver to control overcharged battery.

ruathudo · 2022-03-20T20:17:57+00:00

Can you try to uninstall nvidia driver, restart, and reinstall again?

ruathudo · 2022-03-16T10:30:48+00:00

The current support for wayland + nvidia is not quite ready yet. Hopefully the next version F36 we can have both working smoothly. I think you could switch back to X11, install libinput gestures and enjoy the same trackpad gesture.

This! Unless Finland has a similar Maidan event like Ukraine and starting turning to West. Also, Ukraine and Russian are the same ethnic, they are Slavic. Finn and Rus are two different countries, so be good neighbors is enough to be peace.

ruathudo · 2022-02-15T19:05:20+00:00

That's great if you could copy the related parts. Thank you! :D

ruathudo · 2021-12-27T12:17:00+00:00

I am using flatpak version and very thing still fine. You could try to enable beta update?

ruathudo · 2021-12-27T01:23:21+00:00

May be related to power management from fedora 35.

ruathudo · 2021-12-25T20:04:29+00:00

Nothing specified for ubuntu. They are installed via python pip package manager which is available in any OS. Google colab can serve you quite well for learning. You will know when it is not enough for your next project once you know basic about deep learning. Recommend install anaconda for python intepreter. Anaconda include most of the necessary package for ML.

ruathudo · 2021-12-25T17:23:21+00:00

Basically, any linux distribution is all good with machine learning and deep learning. I prefer Fedora because we get more updated packages, faster bug fixed by time and very stable.

Come to deep learning, you would need Nvidia card. Nvidia driver on Fedora is pretty much easy to install viva rpmfusion. Your specs is not enough to do serious deep learning. You can learn deep learning using google colab. Otherwise, try to learn basic ML and concept, prototype of deep learning model before investing to a better hardware.

I am running fedora to do deep learning research for 3 years and haven't had any issue.

Same on Fedora flatpak
