Snapmaker 2 A250 profile ... speed too fast?

Hello Group,
I use my Snapmaker 2 A250 with Luban to print since a while and the result is pretty good.
So, i want to use the Beta Orca Slicer … I installed ans choose my machine in the setting but it seems to have a huge difference between Luban settings and Orca settings … speed is very fast … probable too fast compare to Luban …

I tried to print with Orca default settings, but the result is very poor … under extrusion on top layer and others problem …

Does someone use Orca beta with A250 with more success ??

Thank you for help and sory for my poor english :wink:

Hello, i have the same problem with a350 and Orca. When printing the Speed is much higher than in Luban. Not generally bad, but the Quality is not very good. Mostly much worse than in Luban. A Profile sync would be great so you can choose between speed and quality…

I know these are old posts, but I just (for the first time) attempted Orca on my aging SM 2.0 A250, and noticed the same thing.

Not only was the projected time way faster for the same model sliced in Orca beta vs. Luban (like 1hr 15 min vs. 3hr 20min) but it defaulted the nozzle start temp to 250C, for plain old PLA, even after I fine tuned their default PLA settings down to like 215C first layer 210C later layers. (On my A250 and the PLA I use thru Luban, typically 205-210C is plenty.)

So due to that massive difference … I did not press “go” on the Orca sliced version… :face_with_peeking_eye:

I wonder if the Orca settings ASSUME one has upgraded to the newer linear rails (A250T etc?) vs. the original 2.0 release rails? All the various choices for machine profile just included variants for dual/single extruder, bracing-kit or not, and QR plate adaptor or not. All of which also postdate the original A250/A350 release.
