great fantastic I would give you the nobel prize, nobody explained this procedure on youtube thank you very much

[@jeffs3dcorner]

Not my method. I'm just sharing it. But thank you.

[@marcdraco2189]

Hey Jeff, thanks again for getting my TronXY Pro 2 on Marlin. I've since adapted a Thingiverse direct drive setup (carriage only) so that anyone can print TPUs now. Works surprisingly well although I didn't do the real donkey work, I just modified the existing Ender 3 design (which is excellent) for the TronXY by moving the CofG 15 mms so it lines up and added a buffer to hit the X-stop.

[@illdourmum]

I have the same printer and love tinkering with it. I'd like to try out Marlin and you have helped me out with getting started. Thanks! I like to use OctoPrint and Tronxy Firmware has some issues with it. I get failed prints all the time.

[@billychampy316]

Great video!!! I have a Tronxy too.

[@swyaznoy161]

Hi Jeff, thanks for your videos. Please answer the question why the .cdb disappeared in VS code. And is it possible to fix it?

[@FlexMoePower]

Thank you Jeff!

[@stevecam1]

Great video, I am not sure what the big stress on "bricking" is I can't understand why Tronxy don't make these a little more easily accessible through their website, still learning about the process used, I was looking for the documentation that demonstrated the loading of update.cbd, I wonder if you could place an executable for the STM32 to dump the flash on boot

[@TheDigitalMD]

It's actually quite easy to brick these now.You can backup, Unfortunately this method for loading firmware no longer works on recently shipped Tronxy printers. The firmware load method has been changed.

[@carlomargherit9728]

Hi Jeff I did email support and the said that if I update my .cbd i will haved noautarization and block the board and printer will be unusable. any sugestion.

[@iverlaek]

Tip: Be aware the board will not reflash the same software again to avoid doing this every time the printer starts and risking to brick your printer. Using the same version you will not hear 6 times the two beeps leaving you thinking something is wrong. Solution: Rename another version as the one you are installing, flash that one (with beeps) and then rename your original file and try again. The firmware you want to install must be called update.cbd. It doesn't matter if it's the original tronxy or a version of marlin, anything different will do. Reload EPROM settings to be sure your version has the settings you programmed in Marlin.

i was thinking about adding another fan to blow fresh air over the motherboard. i want to install it on the spot that is already their for a fan.. dont know why they did not put it their btw. could i simply hook up a 24v fan directly to the power supply or do i also need to put something in to limit the current to it ?

[@anthonyrazo1153]

Hey Jeff, I have a question. When building the Marlin on the v6 191017 board, what kit are you using to compile? Or what board are you selecting? I watched your build videos but it never states what kit or board to select to build

[@smookerstein]

Hi, please advise. In my tronxy xy 2 pro I had Marlin. The printer was mistaken. I requested the original firmware from tronxy support. and according to their instructions, which is the same as yours, recorded it. The bug was not in the marlin firmware and I would like to load it back but it doesn't work. When I put the update.cbd file on the sd card and turn on the printer, the tronxy firmware is loaded immediately. You have no idea what to do with it?

[@ste3364]

if i make backup of original firmware i need also to backup stock parameter file of chitu? or dont need?

[@octopusNavi]

This procedure does not work for me. I have an XY-3 Pro, maybe it is a newer version? my board is a CXY-V6-191017. I put the .cbd or .bin file and it turns on normally, it never updates.

[@christiansorensen9175]

I've run into the same issue, might try burning a new bootloader, but I'm out of my element here.

[@christopherstaples6758]

version I downloaded is nothing like this ? all I can find are erase options , ugh linux version could not do it , windows version did

[@deborahhunke5451]

How do I get rid of the squigglies in the first line so I can run the build command

[@billkaroly]

Another great video. Which do you prefer? Chitu or Marlin?

[@jeffs3dcorner]

Personally marlin. But lots of people do like Chitu.

[@clautazz]

Hi Jeff . I got some issues with Marlin firmware and i want to go back to original software . Unfortunately I didn’t backed up my software and now I am stuck on Marlin . I got the same printer like you with a v6 board non Titan extruder . I emailed tronxy and they come back to me saying that they are in Holliday and they will come back to me after 18 Feb wich it’s crazy I can’t wait that much . Can you please, please , please send me your update.cbd file ? I want to go back on the original firmware as on Marlin my z offset it’s always changing. I heated the bed to 70 nozzle at printing temperature , level the corners of the bed , set z offset properly , did the auto bed level , saved the settings first print all ok . On the second one or third one the z offset height all of the sudden it’s to low or to high and I have to baby step every start of the print to make sure that first layer it’s good. On my FLSun qq s my z offset never varies. After I did the bed level and set the z offset stays like that until I change the nozzle …. Do you know why it’s this happening? What can I do to get same z offset all the time . I got the new glass bed and black bed level sensor , direct drive with dual z rod , new stronger springs for the bed all the good stuff on it but it runs sheet ……

[@ByMechanical]

can anyone help, i followed this to a T from marlinn back to chitu, got firmware from tronxy now powers on but does nothing but can still connect through stm

[@geezerfetus]

I have the X5SA 500 2E. It has the cxy-v9-200415. I can not find any information about this board in regards to Marlin. Honestly can't find much info about the board at all. Do you have any insight?

[@jeffs3dcorner]

Sorry no.

Hi, when I go to backup my firmware on my v6 board I plug in my usb cord from the main board to my computer my windows computer. my computer cannot find a driver for the device. where can I find a driver or what driver do I need to use? Thanks.

Search for USB2serial the latest version has been CH341PT

[@fluntboy1]

hi Jeff , followed all these steps and STM32 flasher stilll cant read from the board.. not sure if Tronxy have some how blocked access to the board by the STMm3 flasher

[@jeffs3dcorner]

At the 7:30 mark in the video are your locks green or red?

[@fnice1971]

a few things to check, unplug USB from printer add to another usb port to change Com Port, check jumper's on board, double check what you changed.

[@thomasdirrigl5537]

I know this is a six month old post but I just wanted to provide an answer for anyone that has this problem. Parity must be set to EVEN on both the computer and the Flash Loader. I found it will not work without this setting.

[@hochuletat7832]

Hello, do you know something about WiFi for tronxy xy2 pro? How i can connect it WiFi?

[@MrGcastle2007]

Maybe it is better to look directly towards the Octoprint project?

[@MrGcastle2007]

Have you returned from Marlin to factory firmware?

[@jeffs3dcorner]

Yes. Last half of video

[@MrGcastle2007]

@@jeffs3dcorner What is better to use for this printer? Marlin or factory software?

[@jeffs3dcorner]

I prefer marlin. If your not having problems with tronxy firmware don't change it.

[@MrGcastle2007]

Thanks for the answer! I also deal with him and am interested in what is better. This is еthe constructor for me, on which you can study 3D printing. Raspberry is coming soon and I'll put Octoprint on it. By the way, the Z-level adjustment began to be done using the dipstick for adjusting the car valves, it turns out to be done very accurately.

[@fnice1971]

@@jeffs3dcorner Agree with Jeff no reason to change firmware if you have no issues, I own 2 Chitu boards they are cheap, 1 for marlin firmware & 1 for Chitu firmware. best way I think. My Stock board stays stock & my backup board uses Marlin.

[@billkaroly]

Chitu firmware? I think my Longer Orange 30 uses Chitu firmware.

[@pvries]

Hi Jeff, unfortunately something went wrong with my Marlin upgrade, and I was not smart enough to make a backup beforehand. Could you share your file with me? We have the same model (CXY-V6-20191017)

[@jeffs3dcorner]

You can try this github should have everything you need. github.com/00shtoobs/TronxyBrainFood

[@martygibson8656]

Hi Jeff.great tutorial. I have a question. I got my tronxy 2nd hand already with marlin2.0 on it. I'm not sure if the tronxy fw is anywhere on the v6 board , I wouldn't think so. I followed your tutorial and wondering if the backup I made is marlin2.0 Is there a way to read the backup file. I expect to see a config.h file and adv file as part of marlin. Thoughts?? My micro sd came with the machine and only appears to have some model gcode files. Did you flash your marlin onto board with the micro when you botted after the tronxy backup was done?
