A dedicated linux desktop or server distro just for klipper would be good. It would take quite a bit of work trim all the fluff and still have a functional system though.
The cron jobs would be easy enough to deal with but all the at calls would be a bit harder to track down. I’ve toyed with the idea of running a bash script to renice some of the resource intensive processes on the fly but I’ve never had the time to dedicate to implementing it.
I’ve got a touchscreen laptop that would make the perfect klipper screen/host but with all the resource intensive processes that run on a standard linux distro it could be more trouble than it’s worth.
It would be easier to run the pi and just use the laptop to connect through a browser. I’m not suggesting it can’t be done, it certainly could. I just take the path of least resistance these days.
It will be interesting to see how he goes with a VM, in my experience it doesn’t matter how much RAM you dedicate to a VM running a linux system. Linux systems tend to use a lot of processing power and leave anything over about 4-6 GB of RAM untouched unless it’s video RAM.
For all intents and purposes, I think having a Klipper host and a “functional system” are mutually exclusive functions in a Linux desktop/laptop.
Making things worse, people always seem to go to the lowest common denominator when choosing the system. I think it may be reasonable in a system with 4 or more cores (with a specific core dedicated to Klipper) but that’s never what people want to use. It’s always an old laptop that they can’t bear parting with that has one core, 1GB of DDR and they kind of have Mint working.
I agree that a dedicated Linux distribution would be great - I’d use it myself but I don’t know if it’s worth the grief when it comes down to the support required for all the low-end hardware out there.
Im rly sorry if i hurt your feelings
Im after long fight today with ubuntu server so im quite angry.
Took me two days to do this.
I menaged to install klipper on pc.
Did install Moonraker and Mainsail.
Flashed bootloader and klipper on my Ender 3.
All seems to work fine i guess.
Its weird because i cant menage to see my printer while connected to usb2.0 port.
On usb3.0 its working fine.
I connect printer with usb cable, and have that configured in config:
[mcu]
serial: /dev/ttyUSB0
When i shut down a pc and start again i cant connect to klipper, need to change that to
[mcu]
serial: /dev/ttyUSB1
or change usb port for cable.
There is any way to attach my printer in different way so it search deviceid or something?
Its kinda annoing.
Thats the only problem im experiencing right now.
I know you have already decided to try klipper but just the fact you will no longer need to recompile the entire firmware from source every time you want to change something or a new version of marlin is out is reason enough to switch to klipper. Forget the faster printing and all the features.
