Sv04 firmware alternatives

So now i have tested
Klipper (bully)
And i got always an error when heating E1 and E2
But i do not like how klipper and the screen work together

I changed to boerns marlin fork
Works well…

Next i have checked johncarlsons marlin fork
Works also for me.

But johncsrlson has inputshaping so i keep this .

I had an issue with filament run out but it looks like the sensors are switched may be this is firmware or an mistake from sovol.

Which k factor is best for sv04 ?
I have 0.05 now with good results.
