Isn't using the Extrusion Multiplier like cheating?

No, the Flow rate or Extrusion multiplier is to compensate for different materials and temperature ranges. Where does the factor come from? Let's say we calibrated our nozzle for work at 200°C with ...

First 3 mm prints poorly, then fine after that

After much trial and error, I think I finally figured out the solution. Even though I could get better prints by tweaking with the temperatures, I could never totally eliminate the problem. The ...

Slicer line width vs. extrusion multiplier for layer adhesion?

Generally speaking, both settings result in the same1: The feed rate of the filament gets adjusted. Either you set a general multiplier, or you demand a wider line which does make it set a higher ...

How is the E argument calculated for a given G1 command?

Basically, all movements are (small) straight lines, the volume of a straight line is easily calculated as you already guessed. To calculate the volume to be extruded you multiply the following ...

Print came out like a wafer

The phenomenon you experience is called under-extrusion. Under-extrusion is the effect of extruding lesser filament than required for the print. The result of under-extrusion (depending on the amount ...

I am experiencing some severe under extrusion

Assuming your filament dimension settings are correct and your extruder is correctly calibrated... Your extruder temperature may be too low. While 184C can be hot enough, it is very near the bottom ...

Is resin 3D printing considered "additive"?

Resin printing (aka stereo lithography) was actually invented before (FFF/FDM) filament extrusion printing. The term 3D printing was more or less created as a generic way to name and describe both ...

Extrusion adjustment

SHORT ANSWER You're not supposed to do the single-wall perimeter thickness test to calibrate Simplify3D. That screws up the extrusion volume. The correct volume calibration procedure for S3D is: ...

Would a really short melt-zone be beneficial

There is a trade-off between the length of the melt zone and the speed at which you can print. The filament itself is somewhat of an insulator, so as the outside of the filament is heated up by being ...

Extruder doesn't retract on inner wall lines thereby causing stringing

Isn't using the Extrusion Multiplier like cheating?

In addition to the very detailed answers above, I would like to mention that the hardness of the filament plays a role too. Most feeders are spring loaded, therefore it depends on the hardness of the ...

Print came out like a wafer

Underextrusion. I suggest upgrading to Cura 3, as you are working with a version 1.5. If you print PLA, you print WAY too hot (190-200 °C Nozzle, 60 °C Bed), if it is ABS, knock down the temperature ...

Hot end jamming very quickly

You are suffering from what is called "heat creep". Molten filament is creeping up the heat break and into the bowden tube, where it is causing a jam. You need to install a proper radiator block that ...

How can you calibrate extrusion multiplier value in Slic3r WITHOUT changing printer settings in memory?

Divide the amount overextruded by the desired amount. If you wanted 100mm but got 101mm, that's 1mm extra, or 1% over. Use an extrusion multiplier of 0.99 (1% under) to compensate - AND THEN DO ...

What causes these round corners

If it's on each corner, and not the layer change corner, it's a combination of overshoot and the short "pause" of the printer when it changes direction. You can minimize it, but it won't go away ...
