Mk3s - Einsy - Pi Zero : Making a Ratos Lite ?
Hi all,
I've been running Klipper/Mainsail on my bears for a while, on PI Zero on UART (not the pi 2 Zero) : The Einsy can't supply enough amps even for a Pi3A+ and, without any fancy stuff (cameras...), the Pi Zero does the job very well.
I wanted to update them to Ratos 2.0 for a better farm consistency.
The config is really tuned as I like it (great job !), but even the 32bit version looks too heavy ("timer too close" crashes).
Can I remove sections like crowsnest and other ressource intensive stuff via putty and do I guess removing sections from Moonraker ?
Thanks a lot in advance, I intend to spend the night on it !

Can I just remove ~/crowsnest, klipperscreen, linearmouvement... crowsnest, timelapse folders and make moonraker "lighter" by removing the matching sections ?
I don't think it works that way
Yeah, seems too easy. Anyhting like "cd ~/crowsnest
make uninstall" ?
Why are you trying to uninstall Crows nest?
As in what proof do you have that uninstalling crows nest will allow it to run without issues?
I have no proof, it's just an example. I'd like to identify the most CPU intensive processes..
I would SSH into the pi and run
top to see what is using the most CPU - but my guess would be klipperOK thx, will do that. Probably yes, the thing is the Mainsail distro runs fine as such
You can disable the services for crowsnest and klipperscreen, the rest has no runtime impact unless configured. (which it isn't by default)
Generally though the pi zero 1 is not supported, so YMMV, RatOS isn't really designed to run on those, it won't do resonance analysis etc.
Oh thanks !
I know on resonance analysis, I do it the manual way on bed slingers and, as Jo Prusa said the other day, all his printers run the same input shaper settings. I see the same (across much less printers than him). The V-cores are much more individual specific, probably due t the heug belts compared with bed slingers.
I have a functional Ratos Lite version ! I've installed it on 2 printers and so far so good. I'll let them print a few hours prior to celebrating, but looks good so far.
