Other than Moonraker being very unhappy about some path stuff (well I am too, took me 3 tries to get Klipper, Moonraker and Mainsail on the 8GB CM3 
) and struggling with the Pi not finding the printer mainboard under /dev/serial/by-id/ (yeah yeah I should have listened to my own words) it’s printing…
bytes_invalid is zero across the board!!!

and yes… it seems like the Raspberry Pi Imager MainsailOS 64/32bit has some older kernel?
Raspberry PI OS LITE 32bit (Bookworm):
pi@pi:~ $ uname -a && getconf LONG_BIT
Linux pi 6.6.74+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.6.74-1+rpt1 (2025-01-27) aarch64 GNU/Linux
32
Mainsail OS 1.3.2 is Bullseye based I guess?
(Any tips on how to proceed with the Moonraker issue would also be greatly appreciated)
