I have a cluster of 3 Minisforum MS-01 Mini PCs running Talos Linux for my k8s cluster. Previously, I had set these machines up using Debian & K3s for the cluster and configured Thunderbolt Networking by follow this video by Jim's Garage Which is baed on this gist series from scyto
This is how I have mine connected, this means that each one of the my 3 nodes has a cable going to the other two nodes
Hi everyone,
With the recent changes La Marzocco has made to their firmware and connectivity, the approach used in this integration is no longer feasible.
Specifically:
Thought I should post my guide on how to do this, as I've struggled with this for quite some time now. I wanted something to bypass the NAT/router as I did not have the option of port-forwarding. I will also be moving quite some in the upcoming year, so dynamic IP was almost a given. And obviously I wanted it to be cheap. This does it all.
This is free, no port-forwarding required and no static IP required. Wildcard domain and SSL certificate supported. It works with Cloudflare tunnels, Cloudflare DNS, Nginx Proxy Manager and obviously TrueNAS SCALE.
I am not a professional, if you see a flaw in this design, please let me know!
There is a lot of confusion as to how to get good ADXL graphs. For many, the issue is printer build and rigidity. For others, there is often an issue with ADXL mounting or noise. Like all of my guides, this is targeted at people chasing the highest performance with quality. If your quality and speeds are fine for you, stop reading as this guide isn't for you.
There are a few parameters that play into your measured values and this will break down the most straightforward. Broadly, they are mass and stiffness. This explanation will not be true in every single instance, and is definitely not PhD level physics, but should at least help with the broad understanding of what your printer is doing.
The easiest way to think about it is if you start by thinking of your printer as an undamped simple harmonic oscillator.

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.
