kiauh VS Print-Tuning-Guide

I just installed Ubuntu server and then used KIAUH to install Klipper. I was up and running in less than 20 minutes.

You can install Ubuntu on any spare laptop/desktop you might have and install Klipper using kiauh. https://github.com/dw-0/kiauh

There are several options for other firmware, the popular ones being Marlin, MRISCOC (“professional firmware” as you see it called around here), and Klipper. Klipper is the gold standard and I highly recommend it. People talk about how difficult it is to install, but it literally takes 15 minutes with KIAUH (an installation script that makes it dummy proof). There are tons of written and video goods online.

2: Download Kiauh

Second download the gcode_shell_command.py the script is currently maintained here, I'm including the Author's warning

Give it a try. It makes things so much easier. Follow the instructions on https://github.com/th33xitus/kiauh from the section "Download and use KIAUH". Then start it by: "cd ~/KIAUH & ./KIAUH.sh" There choose install and you should see an option to install crowsnest. If that doesn't work, try either deleting the existing crowsnest directory, or uninstalling it using KIAUH. Whatever works. Then try to install crowsnest again. Let me know if that solves your problem 😊

Use Kiauh to install Klipper, with it you will be able to install Octoprint as well. It's the easiest way to have all set up correctly.

If you don't remember what you did just start over rather than dissecting what your raspi currently runs. Thanks to kiauh installing the whole deal takes like an hour, where 45 min is waiting for the thing to think. One cam should work out of the box, for two or more you need crowsnest iirc, which you can also install through kiauh.

HF: 24mm3/s, UHF: 30 mm3/s according to this page, presumably using the measurement method also described there. But according to the website it can be up to 75mm3/s but they don't specify whether that's for the HF or UHF (I assume UHF).

https://github.com/AndrewEllis93/Print-Tuning-Guide you can't go wrong with this.

you can increase top flow for cca 5% and test it on some test cubes to see if it helps, also check https://ellis3dp.com/Print-Tuning-Guide/articles/extrusion_multiplier.html#examples

Huh? Your TEST_SPEED macro is taken directly from Andrew Ellis (here).

In your case here, the first thing you need to do is start with your Extrusion Multi. ASA often requires as much as 10% lower than other filaments. So go ahead and head over to the Andrew Ellis Print tuning guide and look at the EM section, pick up his blank cube and follow directions. https://github.com/AndrewEllis93/Print-Tuning-Guide

Sure! I set it up according to this https://docs.vorondesign.com/community/howto/samwiseg0/btt_smart_filament_sensor.html. I'm also using Andrew Ellis' pause and resume macros from here https://github.com/AndrewEllis93/Print-Tuning-Guide/blob/040d31c6daaed23c2a1a353545e7ee442a232f32/articles/useful_macros.md.
