It is preferable to paste in the actual code instead of a picture of the code. This allows users in the future that do a search can actually find your code.

This [suggested edit](https://3dprinting.stackexchange.com/review/suggested-edits/16980), whilst an admirable effort and attempt at transcribing the screenshot, is ***not*** exactly the same as the G-code in the screenshot. There may be some differences. It would be ***much better*** if the OP could just paste in the **actual** G-code..

It seems like your extrusion multiplier might be off.
Apparently you're using a layer height of 0.06 and an extrusion width of 0.15. For your moves (traveling around 1.5 mm diagonally) I would expect 0,0135 mm³ of filament being extruded. However, your extruder only moves 0,00031 mm, which would be 0,00074 mm³ with 1.75mm filament or 0,0019 mm³ with 2.85mm filament - off by factors of 18 or 7 respectively.

No extrusion, but manual extrusion works. The motor turns but no filaments pushed down

My printer doesn't have extrusion but when I push it manually it extrudes just fine.
The extruder motor turns but it won't really push the filaments to get extruded.
I am using the same G-code file that was used two years ago and back then it extruded without any issue. But to think it is the problem of hardware. The extruder extrudes well when I tried to prime the filament (I use gel). So I am confused whether this is a problem of extruder hardware or G-code.
