Ellis' generator is itself adapted from a generator developed by Sineos for Marlin, which is licensed under GNU General Public License, version 3. Any way here is what i added and got sync automatically in the BS , the second command is actually what Orca slicer generates in the g-code, but i used the simplified version it seems to be enough not quite sure that L and M are correct but when sent with it also works and that is the default output from Orca slicer. According to the preview the slow section is 20 MMS while the fast is 27 which isn't a huge variation so it's hard to tell. r/OrcaSlicer. There is no way to "implement" linear advance in G-code, because G-code does not even have any notion of acceleration and deceleration. Go to the filament settings, then enable the “Pressure Advance” setting and keep its default settings. Da ich keinen X1C habe und auch kein PETG von Bambu Lab verwende, fahre ich für jedes Filament vor dem ersten Druck 3 Tests mit dem Orca Slicer: Temperature Tower; k-Value bzw. There is a flow ratio setting for the filament (filament_flow_ratio) and a flow ratio for the printer (print_flow_ratio). I decided to try out calibration using Orca and got noticeable improvements in print quality by just changing the pressure advance. Remember to unzip the files and then proceed with. 040 Is that normal ?. If you want to push your filament further just do Max Volumetric speed speed. So which result is be reliable? Most irritating for me is that the manual calibration in BS and Orca deliver different values. Enter the corresponding value in your slicer’s filament gcode override. Divide 1mm by layer height in mm, then round down, to get the number of layers per flow rate step increase. Then change the “End EA” as 0.
