Calculating the damping ratio for your hardware:

Prerequisite - Outdated. I don't use the resonance testing branch or pulses method anymore.

I recommend running Dmitry’s latest resonance testing branch and using the pulses method outlined below:

https://github.com/Klipper3d/klipper/issues/4560
https://github.com/dmbutyugin/klipper/tree/resonance-test-methods

I would only go down this path if you're getting ghosting with really high speed prints. On the Annex Engineering K3 for example, no matter how perfect the graphs looked, I was still getting some ghosting. That prompted me to go down this path. I'm now able to print at 20-30k acceleration, 250-350mm/s, and 15scv with perfect quality that can usually only be seen at significantly slower speeds.

The default settings in Klipper have the damping ratio set to .1. This should be fine for most people with sane settings. I like to go for the insane.

Wireguard Optimal MTU

About

  • I faced bandwidth issues between a WG Peer and a WG server. Download bandwidth when downloading from WG Server to WG peer was reduced significantly and upload bandwidth was practically non existent.
  • I found a few reddit posts that said that we need to choose the right MTU. So I wrote a script to find an optimal MTU.
  • Ideally I would have liked to have run all possible MTU configurations for both WG Server and WG Peer but for simplicity I choose to fix the WG Server to the original 1420 MTU and tried all MTUs from 1280 to 1500 for the WG Peer.

Testing

  • On WG server, I started an iperf3 server
  • On WG peer, I wrote a script that does the following:
    • wg-quick down wg0
  • Edit MTU in the /etc/wireguard/wg0.conf file

Booting (Debian) Linux directly from the UEFI boot manager

With a modern UEFI motherboard, it is possible to boot Linux directly from the UEFI boot manager, without relying on a boot loader like GRUB.

First, the kernel has to be compiled with the "EFI boot stub" option enabled, which modifies the kernel so that it can be directly executed by the UEFI boot manager.

Debian enables this flag: grep CONFIG_EFI_STUB /boot/config-*

Second, the EFI System Partition (ESP) must be large enough to hold the kernel and the initrd image. The UEFI boot manager executable files must be on the ESP; therefore, the kernel and initrd must be on the ESP, since the kernel is the EFI executable, and the kernel requires the initrd to be somewhere it can find it.

The ESP in Debian is usually 100-250 MB, which is fine.

I've recently joined Amazon Dublin from India and got opportunities to interview with Meta London, Zalando Berlin & some other companies. I extensively researched about companies hiring internationally which support visa & relocation for Tech roles. So sharing list of companies:

Do consider to STAR, if it helped you.
