Good morning! good evening!
Welcome to my video again.
This is my last video about Ender3 version 2 Afterburner
You probably noticed in my last video, it does not print on the centre of the bed.
Actually in my case, the first line went out of the bed completely.
let's have a review what happened here.
Let's use the x-axis as an example.
When the stock hot end mount hits the end stop
The nozzle packs at expected zero position
But the nozzle position can be changed sometimes, in my case, I mount it onto a after burner,
so it goes to a different position which is outside the bed
This can be fixed by telling the printer when it hits the end stop, the position now is not zero,
in this case the end stop position is on the left side of the expected zero.
So if we set this end stop position to a negative offset instead of
current value zero, then the printer knows the origin is actually on the right side.
Let's find out the offsets and put them into the firmware so we can fix this issue.
I will leave a 3 millimetre margin on the bed
and take a mark. If you use a clipper (use clips) you should leave more space here.
So this position is going to be the origin
That's first home x and y
and then from the printer menu, use "move x"
and "move y" to move your nozzle to the marked position.
Then you write down the numbers.
Let's also mark the BL touch position on the bed.
With this diagram you should be able to measure all the required values.
I will use VS code and platform IO to compile a new firmware.
Here i'm gonna use Jyers firmware version 2.0.1.
You should always get the latest version.
Let's unzip it and open the entire folder
You may want to delete the default configuration files
and copy the one you needed from the configuration folder.
I use the BL touch 3x3 for my default settings.
So I copied them into the marlin folder.
Let's update these values in configuration.h
with the new settings.
BL touch is now on the right side of the nozzle
So the probe can always reach the bed so I delete this line.
You don't have to set up the BL touch offset at the moment because
Jyers firmware give you an option to do it from its menu items.
The last step: we build the source,
copy the generated firmware into the SD card and restart the printer!
The process is the same as how you upgrade the official firmware.
Before I run a test print, let me do some cable management work real quick.
I don't want my final build to look like this.
By the way, I have to cut this chain anchor a little to avoid clearance issue
for extruder collaboration.
There are too many good videos for this topic on youtube so i'm gonna skip the details.
This is how the machine looks. Awesome isn't it!
Finally It's the time for the test print.
I will just start the test print and walk away.
Thanks for watching and see you next one
