One of the features i like about the prusa mini is it gives you a preview of the g-code file
before you print but what if i wanted that same feature on an ender 3v2
is it possible? yes it is. and i'll show you how to do it on today's filament friday.
filament friday is brought to you by the generous donations of these patreon supporters. this is
actually a two-step process. the first step is to add a script to your slicer
so that when you slice it'll add the image to your g-code file. the second step is to
update the firmware so it accepts that special g-code file and displays the image on the lcd.
the first step is go to this website with the full instructions. i'll put a link to this in the
description below. this is all created by miguel i'm not even trying to say his last name but he
does a great job in explaining how to do this and supplies the firmware. the site starts off with
a brief explanation but then it jumps right into the first step and that is downloading the script
that you have to plug into prusa or super slicer or cura. i'm going to show you cura. you have to
right click and save link as to save the file. so you right click on it and save link as and then
you download that file. this is what the file is. save that to your computer. we'll load that later.
so then he gives you instructions for prusa our super slicer and also cura. i'll show you how to
use it in cura. so here's cura you go up to help > show configuration folder click on that and it'll
take you right to all the folders in cura. you go to the scripts folder open that up and we're
going to copy that file into here so here's the file that we downloaded with that right click
just i'm dragging that into the scripts folder and now we just have to restart cura so go back
to cura i'm going to shut it down and restart it i'm running 4.12.1 now i'm going to load a
file i'm just going to load up a CHEP cube for something to work on now we go up to extensions
post processing modify gcode add a script this is where that script comes in create jpeg thumbnail
click on that and it shows you the width and height now don't change these these are the
settings that has to be in order to work close that you'll see this little icon next to the
slice button now we'll just slice it and it'll add it to the g code now i'm going to rename it here
CHEP cube thumb so i know and i'm going to just save it to an sd card now let's go back to the
instructions if you use octaprint he does have some information but the most important thing
for us right now is to get the latest firmware you click on this link i'll put a link to this
in the description below as well i want version 4.2.2 manual mess because i don't
have a bl touch if you're wondering what board you can just look through the vents
in the bottom of your machine and you can see the version right there on the board
so now you want to copy his firmware to an sd card an 8 gigabyte sd card shut your machine off insert
that sd card turn power on and it'll reboot you'll see a blank screen for a bit and it'll
come up with the creality scroll and then you'll see the latest version that you just installed
now remove the sd card with the firmware on it we're going to put in the sd card that has
that gcode file that i sliced stick that in now let's try and print it click on print there it is
check cube thumb and there's the thumbnail showing up right on the display so i did make other
ones so here's one filament this is the matter hackers test print then i also have my chep pawn
and then i also did of course the benchy and there you have it it's working great
i showed you the installation on my mac using cura there's also instructions for prusa slicer
and super slicer and also for windows which is really no different you download the file
move it to the configuration file for your slicer and then that will generate the g-code and then
you update the firmware the same no matter what slicer you're using this is one of those features
that to me only the open source community would create if i waited for this from creality i'd be
waiting over a year probably longer maybe never see it so thank you miguel for giving us this
and for free you can support him on patreon i highly suggest you do that this is awesome
and this firmware seems to work really well now i've also seen that you can do this same thing
on a voxel aquila i'll be trying that next with a different person who's sharing their firmware
and see how that one works i'll save that for a future video i'm sure some people are wondering
can i do this to my ender 3 or into 3 pro well first off you need a new display this is a full
graphics display ender 3 under 3 pro doesn't have that second you should probably just upgrade the
motherboard anyway because then you get silent drivers so if you go to the version 4.2.7
which you can get aftermarket you put that board in your ender 3
you go to a new display you essentially have the guts of an ender 3v2 and at that point you
should be able to run the firmware and get this to work on an ender 3 or under 3 pro if you like
what i'm doing here maybe check out some of the other videos that are popping up and if nothing
else click on the CHEP logo and subscribe i'll see you next time right here the filament friday
