Thank you so much, that solved the issue!

I am using Cura to slice a simple cube. The extrusion amount of the first layer is extremely low, but the other layers are fine. I copied the first 2 layer g-code here, and I would like to know if anyone have an idea to solve this issue. Many thanks! ;FLAVOR:Marlin ;TIME:40 ;Filament used: 0.00241245m ;Layer height: 1 ;MINX:11.501 ;MINY:10.725 ;MINZ:1 ;MAXX:30.501 ;MAXY:29.725 ;MAXZ:5 ;Generated with Cura_SteamEngine 4.13.1 M82 ;absolute extrusion mode G28 ;Home G1 Z15.0 F1800 ;Move the platform down 15mm M302 P1 M83 ;relative extrusion mode ;LAYER_COUNT:5 ;LAYER:0 M107 ;MESH:20x20x5.STL G0 F1800 X30.501 Y29.725 Z1 ;TYPE:WALL-OUTER G1 F600 X11.501 Y29.725 E0.00745 G1 X11.501 Y10.725 E0.00745 G1 X30.501 Y10.725 E0.00745 G1 X30.501 Y29.725 E0.00745 G0 F1800 X30.001 Y29.725 G0 X29.501 Y28.725 ;MESH:NONMESH G0 F600 X29.501 Y28.725 Z2 G0 F1800 X30.501 Y29.725 ;TIME_ELAPSED:9.395881 ;LAYER:1 ;TYPE:WALL-OUTER ;MESH:20x20x5.STL G1 F600 X11.501 Y29.725 E0.14892 G1 X11.501 Y10.725 E0.14892 G1 X30.501 Y10.725 E0.14892 G1 X30.501 Y29.725 E0.14892 G0 F1800 X30.001 Y29.725 G0 X29.501 Y28.725 ;MESH:NONMESH G0 F600 X29.501 Y28.725 Z3 G0 F1800 X30.501 Y29.725 ;TIME_ELAPSED:17.311875
