Hello,
I need help where when I using printing speed sport or ludicrous, the surface will become rought. Do I need to calibrate or need to add more lubricant? Currently using X1E
You’re simply printing too fast since your hotend/flow rate cannot keep up with the speed you are using, IMO. You can disable/lower the speed of the aux fan to get rid of the curling infill.. you can increase infill walls and use a different pattern to address this too. There was a recent bambu studio update which introduced a new pattern which allowed more than one infill wall width. In the end > your printer reaches limitations.
You need specifically high flow branded filament to expect good results at fast speeds. They are formulated to melt quicker, usually be less viscous, and have a lower liquid-phase surface tension.
That being said, you might increase the nozzle temp to try to get it better, but “too fast” is a real thing and with no other data shared than the pic and x1, i think youre going too fast
