Anet A8 Upgrade: Why & How You Should Update Your Firmware - Marlin Install Tutorial

Upgrade bed leveling and safety for the Anet A8 by installing Marlin Firmware. It really should be the first upgrade you do. In the video I talk about more reasons why and how to do the install.
Some good 3d printing stuff:
Glass Bed (i like it): amzn.to/2LQ7y98
Replacement Hot End (if yours get clogged and nasty): amzn.to/2SRJPWy
BLTouch leveling sensor (i use this now and love it): amzn.to/316PWsZ
Download Links:
www.arduino.cc/en/Main/Software
github.com/SkyNet3D/anet-board
marlinfw.org/meta/download/
Additional Notes:
- If Anet 1.0 is not showing up in the Arduino Board menu make sure you install the board definitions ! Take a look at 6:47 and 7:18
- Some Anets are coming with a different board version (1.5) that might show an upload error when installing Marlin. If you are getting an error when installing take a look at this page for some ideas on fixing it: / marlin_firmware_for_an... .
Also commenter MrLateraliss said to fix his v1.5 board he "had to burn bootloader with a USBasp, as well as a 10 pin to 6 pin adapter, because this method doesn't work with the newer 1.5 board.
After I did that, then this worked to flash Marlin."
- If you're not seeing your printer apply the bed leveling compensation, do the following:
- Level the bed through the menu
- Save the bed leveling through the menu
- Add "M420 S1" to your start gcode AFTER "G28"
- More info here: marlinfw.org/docs/features/aut...
- If Anet 1.0 is not showing up in your Arduino Board menu make sure you install the board definitions ! Take a look at 6:47 and 7:18
- If you're getting an error like: avrdude: ser_open(): can't open device "\\.\COM1" when trying to install the firmware, make sure you are not connected to your printer in another way. Like through a slicer, etc. (thanks Joe Robidoux for this tip)
- If you find that the thermal runaway protections are too precautious you can change them with the settings shown here: marlinfw.org/docs/configuratio...
- A few people in the comments mentioned that you can change the name shown on the printer by changing the "#define CUSTOM_MACHINE_NAME" line. More info here: marlinfw.org/docs/configuratio...
- Jeerka mentioned in the comments that you can change the language by finding the "#define LCD_LANGUAGE en" lines and changing "en" to your language. You can find a list of languages here: marlinfw.org/docs/development/...
- I do not cover setting up a sensor in this video. But I have been using a BLTouch with Marlin and found most of the info to set it up here: www.thingiverse.com/thing:209... I also took some notes which you can find here: gist.github.com/MatthewRayfie...
- If for some reason you need to downgrade to the original firmware you can find it here: www.3dprintersbay.com/anet-a8...

i have searched around for A simple marlin how to and never really found a good one until yours, and nobody ever mentioned anything about that bed leveling thing thanks for sharing!!

[@MatthewRayfield]

You're welcome, glad it helped ! And you're right about no one mentioning the LCD bed leveling, that's exactly why I wanted to do the video

[@sparksycat]

I did 7 hours of research trying to do this today and you managed to explain so well in 1 video. I now have a 3D Printer with Marlin. Thank You SOOOOO MUCH :)

[@MatthewRayfield]

Good to hear ! Glad it helped !

[@MigMonkey]

Just upgraded mine, if anyone else gets confused like I did because you can't find the Arduino folder in your documents folder, you have to run Arduino once first. Then close it out and the folder will be there! Great tutorial, thank you!

[@MatthewRayfield]

Ah good tip ! Glad you liked the tutorial

[@marceldeman1541]

Did that but did not find the folder labeled documents but it must have made one because I do not get the message anymore. it is not in the list like Mathews

[@koaasst]

ahh cool worked for me, the arduino installs in the Program Files first so go look there peeps to find the file to run Arduino, then documents has an arduino folder you can put the hardware folder in. oh computers you so crazy

[@hazonku]

I kind of just figured it out logically but then came back to share this & you already had, so thanks for that!

[@m4nuz]

Thanks mate!

[@goyslop4289]

Thanks Matthew, this was by far the easiest guide to follow for marlin (at least for a complete tech noob like me.) Install went quick and smooth, marlin is awesome so far!

[@MatthewRayfield]

That’s great ! Glad I could help

[@jmachadom]

Easy to follow and very accurate, had Marlin installed in 10 minutes. Thank you for the tutorial.

[@linandy1]

THANK YOU !!!! Why would anyone give you a thumbs down? Seriously. I am doing the firmware update, following you step by step. Well done ! Thanks for doing this video !

[@MatthewRayfield]

Glad it helped you ! : ]

[@luciagarbo]

I just wanted to thank you for making this video! I always thought upgrading Anet's firmware to Marlin was VERY difficult, thats why I hadn't done it in the past. Until now, I found this video and its VERY simple I now can say that my Anet has Marlin firmware, THANKS.

[@MatthewRayfield]

Awesome! Glad I could help !

[@wsandaruwan]

Still works as of Feb 09 2021. Use the exact same versions of Arduino IDE (version 1.8.5) and the Marlin (1.1.x) as shown in the video. I was struggling for hours with newer versions of those with no luck. Finally worked when used the same versions of software on windows 10. Thanks Matthew !

[@KoreyMacGill]

hey thanks for a well put together video! just printed off parts and upgraded my anet with an e3d hotend and bowden system and your video helped me figure out all i needed to get my firmware updated with new offset definitions. nice job with the vid.

[@MatthewRayfield]

That's awesome to hear and glad I could help ! I'm envious of your e3d hotend upgrade. My hotend gives me problems but I've been lazy to upgrade. Maybe sometime this year I'll get to it ! Cheers

[@KoreyMacGill]

@@MatthewRayfield it's a great upgrade. Really am loving it. The quality of my prints sky rocketed once I did some test prints to hone my settings. With all metal hotend just remember heat creep is much more likely. So don't overheat.

Thanks for the video! You saved me a whole lot of trouble with the levelling feature on my Anet A6 printer. I installed from Octoprint and had to disable SD Support to make enough space, but it's working like a charm!

[@MatthewRayfield]

Awesome ! Glad I could help

[@smeet013]

Just followed your exellent instruction to install Marlin on my Anet A8. Thanks! Everything works fine now.

[@MatthewRayfield]

awesome ! glad i could help !

[@flippedout]

Great Video Matthew Rayfield! Thank you. Everyone doing this to update to Marlin 1.1.9 now will get a "Non-constant condition for static assertion" error when trying to update an Anet A8 board using this instruction video. To make it work all you need to do is go into your Arduino IDE and load TOOLS/BOARDS/BOARD MANAGER and search for "Arduino AVR Boards" - then click on "Arduino AVR Boards" and install version 1.6.23 by picking it in the dropdown on the left side bottom where it says "Select Version". After you install 1.6.23 this earlier version of the Arduino AVR boards code is not bugged and your firmware will update. Happy updates.

[@smcwall]

Thanks for you instructions, I ran across this issue too and you saved me hours of stress

[@yoricks5288]

Thanks a lot, Great Man! I had the same issue. Your comment should be pinned on the top to help others with this trouble. (sorry for my weak English)

[@MrStringybark]

[@ludodg]

Dear sir, A well documented and clear explanation of the why and how. I found other info but that often was not so easy to understand due to high nerd-levels vs my lack of programming-experience.

[@MatthewRayfield]

Awesome ! Glad it helped you out

[@ludodg]

had problems flashing though. Finally succes when I first re-installed the drivers that came with the original SD-card. It seems my OS (Windows 10) had problems communicating with the anet 1.0-board. Thx again!

[@garycaselman9843]

Thank you for this video. Everything went pretty well. It did have to init the card before it would recognize it but other than that was smooth thanks to the guidance. Appreciated.

[@kerrymurphy4068]

You are a profoundly likable nerd. Your video is informative and entertaining. Excellent combo. Thanks for this tutorial. I had the same heat bed plug burn out (replaced the wire harness with a beefier one that includes two leads for both + and - connection) and don't want thermal runaway to burn down my house. I have also read stories of runaway also happening @ the hotend- heating pack comes out from stress, thermister reports that hotend is cold and then heat element runs away and catches cooling fan nozzle on fire and maims your family. I dont like that.

[@MatthewRayfield]

Hey thanks again ! Hadn't heard of it catching the fan nozzle on fire, but makes sense. Dangerous little things I guess. I just stay put clutching a fire extinguisher if I'm printing. (okay not really about the extinguisher, but it is nearby)

[@benchatfield3529]

When I heard the bed leveling thing it blew my mind 😂 that's so useful

[@MatthewRayfield]

ya i thought so ! seems like people don't know about it. glad i could help ya

[@lukewirges1101]

Thanks for making this video! Just followed and it worked perfectly. Was pretty worried about having to recalibrate bu didn't have to do a thing.

[@MatthewRayfield]

Nice ! Glad you found it useful

[@Anthony-ry8lo]

Hay Thank you very much I was concerned about doing this up grade as there where so many conflicting videos and blogs, yours was very easy to flow! Thanks!

[@MatthewRayfield]

Thank you that's great to hear !

[@Anthony-ry8lo]

Any chance you could help us install a bed leveling sensor? Hint Hit!

[@MatthewRayfield]

I'll definitely consider making a video on it. Which type of sensor are you looking to install ? I'm using a BLToch now and could probably offer some info on that

[@Anthony-ry8lo]

I have the Ronxy-08n 6-36 volt sensor I have it installed (mounted) but when I try to compile marlin withe what i think are the needed changes i get "define" does not name a type. I think I am missing a library, searching that now. this is only the 2nd time i have run arduino ide lol the first time was after your video witch worked finer the frog hair. thanks

[@andysouthern1699]

Great tip, my crappy a8 couldn't get to tip temperature on its stock firmware, this youtybe video got me around that. Mine would not write to Arduino until I'd completely exited Cura. I'm going to see what I can do with this board now.

[@dylanbruner8348]

This is the best video i have ever found, great job

[@swone100]

This video is very helpful but I did have to use an older version of Arduino (1.8.5) to make it work, 1.8.9 kept giving an error message. Thank you very much, it’s a GREAT free upgrade!

[@allanmrozek4414]

Well here in 2023 i got my first 3d printer in a week she was flawless then i did a step filament test and has a nozzle run away figured I'd give it a shot and updated the firmware so far so good about to do my first test print to see if it even works!

[@jacklonsdale2722]

Really helpful and so simply explained. Cheers!

[@MatthewRayfield]

Glad I could help !

[@r.e.s.bastler5100]

Hy, and tks for the video, i have now marlin on my machine. Keep on doing the great work. PS sorry for not being abble to give u more than one thumb up :)

[@MatthewRayfield]

Thanks and glad it helped you :]

[@timbatt4477]

Nice video! The only thing that I can think of is to include a checklist of what to move and where. I had to watch the video many times to figure out what you were actually doing. Now I have to relearn my printer menu......

[@DanPowersGoSubaruGoGoGo]

Having had done a ton of Arduino stuff in the past, this video made it incredibly easy. Thanks @Matthew Rayfield! I see some folks are having random issues flashing the A8 controller or their controller getting bricked. It is possible your Adruino does NOT have a bootloader flashed to it (or it was overwritten). This saves a bit of space at the expense of not being able to flash it over USB. In that case, you would need to get another Arduino and set it up to flash over ICSP or get a dedicated ICSP programmer. With the ICSP programmer, you can (re)flash a bootloader and then it will upload like normal. If you can't spare the space, just flash Merlin on with the ICSP. When using the ICSP, select the programmer and use the 'Upload Using Programmer' button instead of 'Upload'.

[@MatthewRayfield]

Good advice !

[@WaynesWorld69]

Well done. Great explained and following your instructions works nicely. I'm about to change my settings back to these as I've just just fitted a glass bed and my sensor doesn't work thru it - so back to manual I go (until new probe arrives or I can get a metal plate to fit under the glass.)

[@MatthewRayfield]

Glad you found it useful ! I'm using a BLTouch with glass and it's working well

[@WaynesWorld69]

Matthew Rayfield I managed to get a thin steel plate and now it works great. Thanks again :)

[@Jeerka]

Thank you... I did it on 2nd try, because i forgot disconnect Pronterface :) ... my fault :) ... Marlin is supercool :) ..I love Bed leveling .. it's awesome feature :) ...

[@vtech4664]

Thank you, that was extremely helpful and easy to follow. :)

[@MatthewRayfield]

Glad you found it useful !

[@Kyle-ye4nj]

Very good!! Everything went well, *just had to uncomment the "**#define** SLIM_LCD_MENUS" inside the "Configurator.h" so that the programm wasn't too big.*

[@MatthewRayfield]

Many thanks ! Glad it was helpful for ya

[@lloydw88]

Hey matt, so i have this exact printer. Im looking at a new extruder end on wish, its a multiple color extruder (3 colors). If i were to buy that hotend, what would i need to add do you think? New board? Or can i add to it? I know i need 2 more motors and i know repieterhost will let you have more than one nozzel. Im just curious if i need to upgrade the board or what i would need to upgrade if i wanted to get the 3 color nozzel.

[@TUNG0701]

thanks for sharing,it's helpful for my anet v1.5 board but my print cooling fan doesn't turn on automatic when printing after upgrade to Marlin 2.0 ,is there any configuration that I need to change?

[@FarizalMustaffa]

I recieved a board written as "V1-5", does method in video still apply or do I need to configure something else? Thanks.

[@TheHeliman9]

Quick question first of all great tutorial on to upgrade firmware easy and painless so the question is after I go through manual bed leveling through LCD menu and start a print the printer head always winds up to close to bed surface and is not extruding is there a quick adjustment for that while printing through their tune menu or am I doing something wrong thanks I also want to add a proximity sensor so I don't have to go to the headache of that

[@scottbarnard2422]

Hey Matt - What is your work-around for "arvdude: ser_open() : can't set com-state for "\\.\ COM3" ?" I've tried uninstalling/re-installing the driver, re-booted the computer (Windows 10), and reset the Anet... Still the same error message...

[@ToastmastersFCSS]

Great video, thank you for the info and instruction

[@benluke1897]

Matthew i have just completed the firmware upgrade as per your video but when i complete the bed levelling, the extruder at points 4 and 7 are not on the print bed. Can you help me in moving them?

[@tbaxter08700]

So do u take the z endstop off when you do that manual leveling what you said?

[@cyberstar251]

[@MatthewRayfield]

Glad it helped ya !

[@kylebaggott1479]

Great tutorial. I am having some issues with the bed levelling not saving but I think that will be solved by adding the command in the goose. My main issue is that no matter what I enter in multiple slicer my part (radial) fan always sits at zero unless I manually override it using the LCD menu during a print. Any ideas?

[@MrPHILLIPS369]

Thank you so much. Worked great. You hopefully kept me from turning my house to a pile of ash. Restart your computer after downloading everything. Would not connect to com port till I restarted.

[@johnm0eou]

Hi the changes that you made to the software in marlin can this be sent in print instructions to follow as you went through the video a bit fast Thank you john

[@UKCM]

Do you know how I can set up Marlin onto the Anet A8-M? I have tried this and so far I am getting errors while uploading ..

[@Vandy91]

About the heated bed connector burning: From everything I could tell when it happened to me, its because the connectors are cheap and not properly seated or crimped. I soldered the wires directly to the pins and have not had any issue since. It was the loose connection on the pins and when the heated bed moved forward and back, it moved the pin around causing sparking inside the connector, ultimately heating up and burning the connector.

[@jasonshiner2006]

I'm following your directions exactly but it it wont allow me to paste the 2 folders over to the other file. I can copy them but when i try to paste them the paste option is greyed out. Any idea how to fix this? Thanks in advance. Im dying to try this marlin upgrade out, ive been running my A8 for a year now on stock fw.

[@kiplandingham322]

Thank you for posting this...excellent tutorial. Question though: say I proceed to do this with my stock A8, and for some reason I want to go back to the original firmware. Is there a way? Thanks again.

[@MrGeezer101]

I have an a8 with a 1.5 board. I was able to upgrade it with your help. A couple of times I have had some garbled letters on the main screen. If I go to another screen and then back it goes away. Only other thing is I don't see anything about bed leveling. Thanks for your help

hi,i buy a new 3d printer Anet A8 borad V1.7 . When the initial operation, the extruder is directed to the opposite side to the end and continues for a while the engine rotates even when the extruder reaches the end ... The same applies to the surface ... Also, the z direction motor works one and the other does not work .. Note that I almost checked the connections All are correct, What do you think is the problem?

Worked for me, the bed leveling is really handy although the new menu took a little getting used to

[@MatthewRayfield]

Nice, glad I could help. And ya I forgot that the menu changes. I should have mentioned that. It does make more sense though I think to use the middle button.

[@aidanmac2002]

@@MatthewRayfield Thanks for letting us know about the safety issues. It's appreciated

[@sxty8goats]

Did you have to add anything to the G-Code to make this work for you? I've had a few issues. First, the screen seems to scramble into non-sensical characters now and then, and by now and then, I mean always. Sometimes hitting middle button brings it back. But most of all, I go through the manual bed leveling sequence, it finishes I save the settings. I run a program, it ignores it's bed level and tears off my tape. I have 'bed leveling' "On" in the menu.

[@lloydw88]

Hey man, so Im new to the 3td printing world. I have had mine for 2 years and started using it quite a bit this year. So last night I downloaded repetier host 2.1.6, I was on 1.1.9 or something like that. but I upgraded repetier last night, and I just finished your instructions on firmware. So when I uploaded it, it gave me an error, saying com 4 port wasnt available. So I unplugged the usb cord and plugged it back in and hit upload. So it uploaded with no errors. but when I open repetier host now, under the manual control tab, you have flowrate, feedrate, extrder, and bed. Well the bed option is gone entirely from repetier host, like its not there to click to turn on and heat up the bed. I dont know what to do now to be honest.

[@SleepinDevil]

Thanks for the video. It's a great guide! I have a question. If I wanted to add the auto bed levelling sensor (the Anet A8 official one), do I need to only do the first two changes that you did to the Configuration.h file and not the last one? And then I calibrate the sensor in the usual ways found online.

[@MatthewRayfield]

Yes that sounds right. I would have to look a bit more into it to be sure. But you will enable mesh leveling but not LCD related things. There should be some more info online about using it with the capacitive sensors. I am using the BLTouch now which has a slightly different setup.

[@bobaloo24u]

Does anyone have this whole setup procedure in a file or on a CD that I can purchase? I have watched many videos on this and am still confused. I would like to connect my self leveling probe and take care of the thermal runaway issue. Thanks!

[@garyandjanesisk9063]

Installation went good but when doing the bed leveling routine, the z axis will only go up. The LCD shows the amount of z travel, both up and down when the appropriate button is pushed, but z travel only goes up. Even after the z has move up well in to the positive numbers region, it will not move down when the down button is pushed. The numbers on the LCD do go down however. What,s wrong?

[@airhogfpv1283]

As much as I really appreciate your contribution, I found myself getting ticked off because I'm a newb and you're going so dang fast that, even though I can pause, and did a LOT, you didn't tell us if we need the A8 board powered up to do this or not. I've had a ruff day as well, so take that into consideration. Bed sticking is my nightmare right now and the hairspray I picked up just spits out and blobs so I'm hoping with PLA that it will still work. I plan on printing RC airplane parts after I get things all worked out and need perfect 1st layers and thin walls. I'm printing a power switch mount and Mosfet mount for upgrading that stuff. Uggghh.... I have two burned fingers from trying to unclog the crappy PLA that came with the printer. Anyways. I really do appreciate your video. Everything I've touched today has fallen apart. I'm afraid to take a piss now.

[@MatthewRayfield]

Garry Kennedy heh I understand! I’ve had many frustrating moments with my printer as well but it always gets better. A few times it has meant buying a new part because I broke something. And yes I agree with the speed thing. Had I known so many people would watch this video I would have redone the screen cap slightly more slowly. But thanks for watching and hang in there !

[@garrykennedy5484]

Thanks Matthew. I've got it dialed in now. Printing great and doing a RC airplane tail section right now. 2 thick coats of Aquanet and it's all good. I am afraid of bricking my board but I really want that heating check sum safety that Marlin has. Plus it's not near a computer ATM. That may change soon as well though. Much better day though. I'm hangin'.

[@shalekendar6759]

I have the A8-M (has the 2nd print head already). Would I still use the same config files (the A8) or do I need something different?

[@MatthewRayfield]

This is just an educated guess but... I think you can start with the existing A8 config and modify it. I would go through Configuration.h and read the comments and think about if each setting needs modification. For example, one of the first settings is #define EXTRUDERS 1. This would need to be changed to #define EXTRUDERS 2. Marlin has great documentation where you can search the name of each configuration setting and see exactly what it does. It looks like a lot of the settings for dual extruders comes in through the slicer by way of gcode, so there may not be that many changes needed. Hope this helps !

All this process seems tied to MS DOS, is there an Apple OS based process?

Matt, Im on the Arduino site to upgrade my Anet A8 firmware...The latest release is 1.8.10..the one you show is 1.8.5..Should I be able to do exactly what you do in the video with this latest version? Thanks. I Like your videos! - Rich

Have you tried updating marlin through cura 4.0.0 yet

[@adriasendraandres3952]

Once I upgraded in my anet a8 the X motor stop working left, just right (positive). Idk why it happens but it looks like recording the true position. If i try to go to the home Y and Z work well but X start to go right (instead of left) without stop (even if it cant because is on the limit) and finally I must disconnect. It's so distracting. ¿Do you know how to solve it?

[@MatthewRayfield]

I don't know what would cause the going in the wrong direction thing. Sorry. Perhaps try checking your cable connections ?

Hi - Great video but mine fails with a problem uploading to board. Do you have any tips on why this may be?

[@MatthewRayfield]

Make sure that you have the board definition installed and that the printer is on and connected. Another issue can be that a slicer or something is also trying to connect to the printer.

hi there im trying to download the marlin from the website but it seems like the after i download the file... it cant be zip cause some file are missing can anybody help me with this?

[@MatthewRayfield]

That seems very odd. Not sure what would cause that.

[@Goaliejoe192]

Thanks for the video, though when I try to upload, I always get the following error code: avrdude: ser_open(): can't open device "\\.\COM8": Access is denied. Any ideas? I have multiple ports in the menu, but I verified that this one is the correct one by unplugging the printer and checking which port disappeared

[@Goaliejoe192]

My bad. After some more googling, it was because I had the printer open in Cura. Thanks again for the video

Mathew Well I did what you said and it changed my firmware but I am not sure it is working right. I only get one menu with 4 lines and does not let me get to the homing or to move the steppers let alone the probe the bed leveling. I changed the board as I had the old on that was long and narrow but never got the thing to work as the z axis homing switch would not work. so now nothing works. any thoughts not what you would call a programer for computer software. I was running only with an sd card befor as I could never get the usb to work .

[@MatthewRayfield]

The menu won't work at all ?

[@yantzee0014]

@@MatthewRayfield I have the same issue. It flashed, but the menu will not function at all.
