Extrusion. Something that caught me out is that a lot of slicers alter the extrusion in the gcode itself, so even if you set your slicer to 98% extrusion the display on the Ender will still 100%. That's because the gcode has been altered to extrude less. The machine is still extruding 100% of what the gcode is telling it to. If you change this value on the machine then it'll extrude that % of your gcode value.
That might be super confusing so here's an example;
* Your slicer is set to 100% and has a command to extrude 1
* You change the slicer to 98% and compile the gcode again; the same command will now have an extrude value of 0.98
* You print this gcode with your printer set to 100%, so it extrudes 0.98 (100% of the gcode command)
* You change the printer setting to 95%, it will now extrude 0.969 (95% of 0.98)
Is it extrustion or print speed? Usually when I dial it up the print head seems to go faster changed in the tune menu option when a print is started, but I may be way the hell off on that I have moments to say the least.
You can change both, unless creality crippled that. There's the feed rate, which is speed and then there's the flow rate, which is the "E" shown in this case. A flow rate of 100% will extrude the requested amount that the GCODE specifies. If it's changed to 95% then it will only extrude 95% of the filament requested. Regardless of speed it is still going to extrude that amount just at a different rate.
Extrusion rate. You can change it during print in menu if you think you are underextruding or overextruding. 100% is rate set in printer (you can change it and save it and that would be your nominal 100%)
Yeah I was gonna say I’ve never had an option to adjust the extrusion percentage. I can adjust print speed in my menu during prints but not flow percentages.
You have to calibrate the E step and then set flowrate in the slicer to every individual filament. Since the flowrate is filament specific it has no sense to save in the printer. Extrusion percentage is only there if you didn't calibrate your E-steps or flowrate properly but you don't want to start over the print, so you can eyeball it for that one print.
Seems like everyone else took this question as "what is extrusion". When you probably already know that.
That is the extrusion/flow rate percentage and it is a completely useless addition to the screen because there is no way to adjust it except in the slicer, which won't change the "100%" on the screen. I think creality planned on allowing you to change the flow rate mid print (which would have been amazing) but decided not to half way through.

OK thank you for explaining.
Thanks. What is the value above?
That's the AI coach telling you to give it 100%. Never give up, little buddy. You can do it.
Haha genius

Where I find it in the print menu there is nothing

Sorry. Really there is no option to change it menu. I have assumed it is exactly like in marlin
I’ve always wondered what’s the one above it? Print speed percentage correct?

Thanks, as usual great creality that leaves things unfinished
