2 years ago Hello everybody,
To preface, I am currently working on a SuperSlicer profile for the X1 that uses the "Autospeed" function to set a base speed from the maximum volumetric flow rate then it modifies that base speed as percentages for all moves. Essentially this automatically sets all speeds for me based on my layer height, line width, and the maximum flow of the filament (note in Bambu Slicer if using a slow flowing filament and high layer height, it is possible to have the entire print go at the same speed because it is limited by the maximum volumetric rate. In my design the speeds are all adjusted off of the filament's characteristics.) This is similar to the feature request listed here -https://github.com/bambulab/BambuStudio/issues/126
While going through the start g-code I realized that if Bambu simply draws a high volumetric demand line (unique for each nozzle), let's say a 0.3-layer height x 0.5-line width for a 0.4 nozzle, then simply moves the print head faster and faster to increase the volumetric demand, the LiDAR should be able to "see" where the line width begins to decrease and correspond that with a maximum volumetric flow rate, which would then in turn set most speeds (It may be worthwhile to consider volumetric marlin... instead of trying to match the flow to the movements of the nozzle, match the movements of the nozzle to the flow, based around the maximum calibrated flow rate)
Seems a great idea to me
