Hi, nice job ! However max accelerations for K2 are 30000mm/s2, not 20k ;-)
And max speed is 800, not 1000 :-)

Thanks for noticing this, where do you see this from Creality? In the version of CrealityPrint that I have it is set to 20k for max acceleration and 800 for max speed.

I checked on the latest creality print release with the newest profiles, here is the screenshot ;-)

Ah I see now, I left those values out as they seemed incorrect (mainly with the jerk values). I went with the maximum values from the 0.2, 0.6, 0.8 nozzles as they seem to be the correct ones. What do you think?

Usually with Creality, only 0.4 profile can be trusted, the others have high chances to be incorrect. The K2 is advertised as being able to do 30kmm/s2 so it seems correct. But without being able to get a copy of the printer.cfg, I'm not able to confirm the data.
I hope I will be able to get a K2 so I will be able to test it against Orca profiles ;-)

I'd go with the 0.4 nozzle version if it wasn't for the jerk values. Do you think that the 300m/s jerk values are correct?

[bistory]

If it didn't change, jerk values are ignored by Klipper, it is only useful for the slicer to be able to estimate print time accurately. To avoid those values to be converted to SQV instructions by Orca, we can put some more realistic values like 20mm/s. Probably reuse the same values as Qidi uses for its new X-Plus 4 which advertise the same speeds ;-)

Done!

Merged.
Thank you both!
