 So I've been getting a lot of requests on how to do the firmware on an Ender 3 Max. It's actually pretty simple and today we're going to go step by step on installing the firmware right here on this Ender 3 Max. My name is Jim and this is the Edge of Tech. What's up everybody? Like I said, I've been getting a lot of requests to do the firmware on the Ender 3 Max. So I thought I'd make a quick video and show you how I upgrade the firmware and today we're going to use the TH3D Unified Firmware. I tell you what, super simple to configure. It's fast to install, especially on this one because you don't have to do anything to the screen. And once we get done, you're looking at maybe 10 minutes tops. It's a very fast process on this one right here. So you're probably asking yourself, why would I upgrade the firmware? Well, I tell you what, that's a great question. And the reasons why you might want to upgrade your firmware is if you're having issues, maybe you're having some printer problems and you want to maybe make sure you're on the newest firmware to see if that helps your printer problems. Otherwise, maybe you want the newest features. Maybe Marlin has come out with some new features and TH3D threw them in their package. I know Scott and the crew over at Marlin are always tweaking and upgrading and doing bug fixes. For me, I just like to upgrade the firmwares on all my printers if I can. Just keep some current. Maybe it fixes bugs and of course adds features anytime there's new features added. With all that being said, I don't want to make this too long a video. Let's dive in to how to install the firmware on the Ender 3 Max. I'm going to jump in right here and tell you today's episode is being sponsored by THANX. THANX is the biggest growing 3D community with over 2.3 million available models already. One of the really cool models available at THANX is the new WEXTER Mini Gym. If you guys have not seen the Mini Gym that WEXTER designed, all you have to do is type in Mini Gym. You'll find the STL exclusively right here on THANX. You can download it and print it for yourself. Thanks again to THANX for sponsoring this video. You can find a link in the description below if you want to check it out. Now back to the video. So the first thing we're going to do is jump over to the TH3D Firmware page. You can find that by going to firmware.th3dstudio.com or click the link in the description below. It'll take you right to the Ender 3 Max where we're going to start. So once you get to the page it'll look like this. If you scroll down we're going to be using the Unified 2 firmware and we're going to go to Creality and we're going to kind of scroll down until we find that Ender 3 Max right here and we're going to click on it. So once we do that it takes us to the Ender 3 Max page and if we scroll down a little bit we need to know which board we have. Now mine was a 422 board but in the video I show you how to check which board you have. You actually have to look at the board itself. That's the most reliable way to check it out. In this case I'm going to be using the 4.2.2 firmware from here on out. If you use that 4.2.7 board it's the same step so you just uncomment something different in the firmware config and we'll go over that in a minute. Right now what we need to do is download the firmware package which is this one right here. So we're just going to click on that and download. I've already done that so I'm not going to do it again. Also if you're going to use an easy ABL or any of the other TH3D products that can be printed you can click this STL pack here. It's free. So once you get this downloaded it's very important that if we go down here it's going to tell you that you have to have VS Code set up and ran. Now I'm not going to do that part in this video because I already have it set up and ran but it's very important that you do it. I'll put the link to this guide in the description below. It's very simple to do but once you have it done once that you don't have to do it again it probably will do updates but that's about it. You don't have to install it again. If we go into the download folder where the firmware downloaded all you have to do is open that up and you'll see that I already did this before but I have it right here. We're going to right click and we're going to do extract. Once you do extract I just hit okay and it'll extract to the same place you downloaded it to and you're going to get these folders here and in these folders is where your firmware is going to live right there. The next thing we're going to do is open up VS Code and we're going to open that firmware configuration .h so let me minimize this. I'm going to open this here so once you have a VS Code open that's this one right here then you're going to go over to the open folders tab so you can either go to file open folder right here that's the way I like to do it or there's a side button there and then go to downloads we're going to go into the unified to creality v4 folder. We're going to click on the firmware folder but that's it just leave it clicked and then select the folder just like that. What that'll do is give you this right here and if you expand it there's just a ton of stuff in here. Now what we need to do is find the configuration .h so you're going to click on configuration .h and that'll be under your marlin tab this might be minimized like this so maximize that find configuration .h and click on it that'll open configuration .h right over here and from here it's very very simple. What we need to do is come down and find our ender 3 max which is right here we're going to delete these two wax which is also known as uncommenting the line so we'll delete these like that and you'll know it worked because it'll actually turn a looks like pink and blue color here so in the case that you have the 4.2.7 board you would just scroll down here and comment out this one right here now this one right here says it's the ender 3 max 4 to 7 board like I said earlier I have the 4.2.2 board so we're going to uncomment this one but if you had to all you'd have to do is scroll down here to the ender 3 max put your cursor there and delete those two in my case we have the 4.2.2 board so I'm going to delete these two and that's it we're done there's nothing else we need to do now there's a lot of other things we can do but there's nothing else we need to do if you scroll down you can see a whole bunch of options if you keep scrolling down here if you have different hot ends you can use them here if you have an easy abl probe maybe you can uncomment here you just find the printer you're going to use in this case we're going to uncomment out that one if you're going to use an easy abl if you scroll down a little further if you have ender extender if you want to change any of the parameters around your easy abl they're right in here if we keep scrolling down there's custom probing maybe you have a bl touch you can use this for custom probing there's different extruder settings you can actually customize the e steps here if you keep going down even further there's just a ton of stuff you can do but in this case we're going to leave it at that all we did was uncomment the ender 3 max 4.2.2 board we are done we go to the bottom here where this little checkbox is and we hit go now this will take a couple minutes to do depending on your speed it could take up five to six to ten minutes i have a pretty quick computer so it doesn't take that long but if it sits here don't be surprised it'll go through all this stuff and when it's done it'll let you know it's done okay when it's done you'll see right here that it created this one right here and it was a success and that's awesome that means we successfully compiled the firmware and now we just need to go find it so what we're going to do is go on the left side here in the firmware folder under pio under build and then find this one right here which is like a big long name and you want to right click that and reveal in file explorer what that'll do is bring it up in your file explorer where it actually saved on your computer here and if you go into the creality folder there you're going to find a bunch because i've done this a bunch of times today but uh you're going to find a bunch of stuff and if you scroll down this one right here is the one we're looking for this is the firmware dot bin folder so this is the one we're going to drop on an sd card so you'll throw an sd card in make sure it's blank and format it and then copy this to an sd card once you have this copied to your sd card uh go ahead and eject the sd card and then we're going to jump into the actual upgrading of the firmware right on the machine let's go hey everybody if you're getting value out of today's video i really appreciate if you hit that thumbs up that like button it really helps send this video out through the 3d printing community on youtube and hopefully falls in the hands of more people who need it just like you i really appreciate it thank you so much for the support and back to the video now we're going to insert the sd card into the machine and then turn the machine on and we'll see what happens here so you see it takes a little bit longer than normal to boot up it should be loading the brand new firmware here when it's completely done we should see a th3d splash screen there it is there and if everything went well it'll boot up th3d unified firmware 2.2.7 that may change yours could be a newer version than this so once the screen boots up you just click the button you'll come down to a bout printer go to firmware info and you'll see th3d unified firmware in my case it's 2.27 it could be a newer version when they release a newer version but you'll see the new version on there in this case it's 2.27 and that's it it is super easy to install the firmware on the ender 3 max and we are done now so that's it it only took about 10 minutes and we got the firmware updated i hope you guys found that pretty easy to follow and super simple to do i know th3d is always updating their firmware package so if you ever see the upgrade you can do it just the same as you did today it will just be a different version let me know in the comments below what your favorite firmware is is it marlin is it clipper maybe there's one i don't know yet let me know i'm very curious to see that also there's links in the description for where you can find the firmware and everything we went through on today's video just look in the description below the video if you've made it this far you guys are awesome i hope you guys learned something today and as always keep printing hey everybody
