ENDER 3 PRO – SIMPLIFY3D – CONFIGURING THE EXTRUSION MULTIPLIER

To figure this out, you can download Teaching Tech’s files on Thingiverse
https://www.thingiverse.com/thing:3071464

Unpack the files

Open up Simplify3d

Import the file called cube

Go to your processes and change the following settings:
On the Extruder tab
Set extrusion width to 0.48
Set extrusion multiplier to 1.00
Drag the Infill slider to Zero
On the Layer tab
Set Top Solid Layers to 0
Set Bottom Solid Layers to 0
Set Outline/Perimeter Shells to 1

Click Prepare to Print for the cube

You should see that the cube is 1 layer wide

Measure the wall thickness of this cube after it prints. My wall thickness measured in at 0.58

Now, to find out if the extrusion multiplier is accurate, run the following formula:
Desired Wall Thickness / Measured Wall Thickness * Extrusion multiplier = New Extrusion Multiplier
(Ex. 0.48 / 0.58 * 1.00 = 0.8275)

I will round the 0.8275 up to 0.83 and set this as my Extrusion Multiplier setting

Now to reprint the cube to ensure accuracy

ENDER 3 PRO – UNDER EXTRUSION ISSUE [SOLVED]

To fine tune your Ender 3 Pro you will need to measure the amount of filament that is passing through the machine using the following test, to ensure your settings are correct

First you going to want to disconnect your hotend from the extruder, and place these in an area where you can heat them up and they will not damage themselves or anything around them.

Next you’re going to want to go into the settings of your Ender 3 and click on preheat PLA. This will warm up the hot end and allow you to extrude for our test

Measure out 120mm from entry point on extruder to the spool, and mark it on the filament using a notch or a marker (I prefer a slight notch)

Open Octopi
Go to Terminal Tab
Enter in the following code
G1 E100 F100
Press Send
This will extrude 100mm of filament

Now measure the difference of what went in, verses what is left.
I extruded 90.5mm instead of 100mm, and have 29.5mm left before my notch

Back in Octopi
Terminal Tab
Enter in the following code
M503
Press Send

Search for M92 line and verify it says E93
This is what you will edit

To figure out the new value for E93 do the following
100/90.5*93=102.76
E93 should be E102.76

The values above translate to this
100 – Distance that should have been extruded
/ – divided by
90.5 – is the distance that was extruded
* – Multiplied by
93 – This is the E93 value we saw earlier

Back to Octopi Terminal Tab
Enter in the following
M92 E102.76
Press Send

Enter in the following
M500
Press Send

Your new settings are saved, and your extrusion will be accurate. Feel free to repeat the above steps to ensure your settings are correct and the extrusion works as expected

ENDER 3 PRO – OVER EXTRUSION ISSUE FIX [SOLVED]

Press Send
This will extrude 100mm of filament

Now measure the difference of what went in, verses what is left.
I extruded 101mm instead of 100mm, and have 19mm left before my notch

Back in Octopi
Terminal Tab
Enter in the following code
M503
Press Send

Search for M92 line and verify it says E93
This is what you will edit

To figure out the new value for E93 do the following
100/101*93=92.08
E93 should be E92.08

The values above translate to this
100 – Distance that should have been extruded
/ – divided by
101 – is the distance that was extruded
* – Multiplied by
93 – This is the E93 value we saw earlier
