Great video! Good points on the filament out sensor and resume after power loss beings controlled by the display firmware. That's something to also consider if installing OctoPi. Love the cat 👍

Good job... I entered the group to see if i would buy this printer, and i was conviced when i saw the community.

Is working Samuël. A cheap Chinese mouse interfered with my com port. The print results are amazing and the steppermotors are a lot quieter. Thanks for your clear video and your response. Kind regards, Rob

Great video. I love it when you try and make eye contact at the angle you were out. ;) Keep up the good work!

All went well for me, no problems with the upgrade. I think the PID settings are off though, has the hot end will overshoot by 8 degrees before settling in. I may run an autotune PID later to see what values it produces.

I just upgraded the printer to the custom Marlin firmware and also upgraded the LCD display. WOW! Like day and night. Super thankful for this awesome contribution! Anyone that has a good Cura print profile to share? Will do some stringing tests tomorrow :)

If I had to guess why they have two separate motherboards it's so they can close source the power off resume and filament detection portions of their code without being in violation of GPL

This is exactly what I've been looking for!

excellent work very instructive, thanks for the time

I followed the steps to upgrade my printer with custom firmware but I encountered several problems. I started the custom firmware with the Arduino software, checked all the settings compiled it and get the message that a library is missing. Tried to install the u8glib but it cannot be found in the library. Whats going wrong? Rob, The Netherlands

Can I ask does it work with CR10 as well? Or do I need a boot loader?

Sam, hopefully you can help, New to the A5 and 3d printing, but have some major issues. Looks like my unit was built in Nov 2017. I updated to Marlin software using your instructions. The issue came with my first print that stopped around 65%. I was using a USB cable and the most current version of Cura. The print was going fine, when I went into the front touch screen and was reducing the fan speed, all the sudden the print just came to a stop. Prints were printing like garbage prior to this, and I've been tweaking the temp, bed temp along with print speeds. Prints continued to print poorly, so I deleted Cura, reinstalled, deleted JGCREAT and reset the printer to the newest (January 2018) hex file of the factory software that I found . I am trying to figure out what is going wrong and if I need to update the touchscreen firmware along with how to update it. I've tried to update firmware again, and re-install cura, same results, maybe worse now, as prints are failing sometimes before the bed and extruder come to temp. This last print failed once via usb, didn't even come up to full temp on bed or extruder, and I tried again via thumb drive and again it failed at the top of the brim. I was tried JGCreat that time. LCD firmware type: MKS tft version: 3.0.0

Where do you get parts for this unit.. like nozzles, etc.?

If you have a modern version of Marlin working adding a bltouch would be possible as long as it's got a spare pin port for the probe as long as the board has enough memory to upload the extra features.

Great video! Thank you for the education

I'm having trouble. The printer says it's not connected in the jgcreat software. Also any setting i press on my printer is not working.

Sorry to go off script, but!!! You seemed to have some A5 knowledge. Since I purchased mine June 6, 2018, I had 10 successful prints. Now the filament is just sticking to the extruder tip and not to the bed, any ideas? Please help if you can

Hi Samuel ... or anyone else who can help me. Maybe I'm too stupid, but I have a strange problem with the 'Custom Marlin Firmware 1.1.8C' for my JGAURORA A5. I'm getting a compiler error: sketch \ ultralcd_impl_DOGM.h: 252: 1: internal compiler error: Segmentation fault ug8lib is installed. Thanks for any serious answers. Addendum: On another PC, I could easily compile MARLIN ... now I understand even less!

Hello Samuel, first of all, thanks for your explanations in this great, comprehansible video! :-) I'm very new in the 3D printer scene ^^ and it will be my first printer. I heard about some limitations within the firmware of the JG-Aurora and issues to get spare parts or custom service from the producer. If I buy an 'JG-Aurora A5 3D printer' next two month, will I get the revised firmware you made for your own, to upload it on my new printer? Or would you advise me not to buy this printer? Can it be a "perfect" working product with your help? - Plan B would be the 'AnyCubic i3 Mega', but it's constructionspace is much smaller and it's printing speed slower. Best regards, and thanks for your request. Dennis, germany

Thanks will be uploading it

Great video. I just purchased an A5, my second 3d printer, based on the information you and Da Hai provided. So far I am very impressed. I have just set it up and tested everything but have not yet done any printing. I have a few questions. If I update to the community firmware does it also provide LCD access to the EEprom and the mesh leveling controls? If not I beleive these would be great features to include as I would prefer not using my computer to level the bed. Thank you

still useful , thanks

Hi Samuel, I have updated to your Custom Marlin Firmware 1.1.8C, but after that my nozzle's X direction remains outside of the hotbed. Do you know why ? and how can I fix it ? Thank you

Would this same filmware file work on the A3S? I hate the filament trail it makes at the start (often oven ruins my first layer...)

Great video! Tried several times to upload the custom firmware with LCD unplugged! Also tried with the LCD plugged in. I followed the readme.txt for build revision C 22 Jan 2018, including adding library u8glib and the modifications for serial monitor M502 & M500. It locks up my A5 everytime. Reflash of original code works fine. Anyone have any ideas?

Thanks Sam for your great work. Does power off recovery works with that firmware?

Thanks for sharing 😀👍

Hello Sam The video is great, but I did not find the hex file for 8:51 minutes on the download link you gave.

Samuel, I updated my Jgaurora a5 firmware. You mention in your vid that with the new custom firmware the error "stopping after a few layers/mid-printing" vanished. However, I still experience the same error over and over again. Tested multiple usb sticks. Multiple cura versions. Also PID tuning, because maybe my instable temperature would cause the printer to stop. Which would be inconvenient, because it stops in the exact same spot each time. Anyone got some advice how to further tackle this issue? thx! PS: Did not update my LCD firmware btw, would that possibly fix it?

Hi will uploading the new firmware fix the issue of z axis reversed? I have a a5s. Thank you

Thanks for the detailed video wonderful work. Did you have to modify the marlin software to communicate with the second mother board? I am also thinking of changing out the heat break on my hot end in order to print at higher temperatures, how would I be able to increase the max temperature? thanks again!

hello, a query, I do not understand English, but I tried to update my printer jgauroraA5, every time in the panel I put print does not print and the temperature of the base does not rise, and I tried to load the firmware again as you do , but my laptop does not recognize the printer and it does not update, I do not know where to download the drivers to conttolar the printer, my laptop (notebook) does not recognize it, and it's new, I'm desperate, I do not know what to do

Hi, have got a firmware custom for 32bit in marlin 2.0?

So if you don't have a square USB cable available could you still do this with the standard port? Or do I have to buy a cable to interface to the correct motherboard?

What will happen if you do not disconnect the lcd pin prior to flashing? thx!

having trouble accessing website

Thanks for the video and explaining how the boards work together. I've messed with arduino's and flashed current Marlin on my other printer awhile back. So I'm a little familiar with the process. I just got a used A5 and it seems kinda flaky. Was thinking an update might help. I noticed in the Marlin example_configurations directory the A5's .h files are present. Is this the same as your doing here? Have your files been added to Marlin? Or is this even more than the 2 .h files? Thanks again for the video. I didn't know you could upload the hex files with Cura. Always wondered what that option was for :)

HI I USE TO HAVE THE MARLIN ON MY A5 BUT AFTER HAVING SOME PROBLEM WITH PRINTING STOP IN THE MIDDLE OF PRINT I WENT TO INSTALL THE MARLIN AND LCD AGAIN AND NOW THE 3 AXIS ARE NOT MOVING AT ALL . HEATING BED AND NOZZLE WORK ALSO SENSOR ARE WORKING AND SHOWING THE TEMP. WHATS WRONG WITH MY A5

Hello there, We bought an Aurora A5 model printer. With 1.75 filament and 100% flow adjustment, we were printing well using the Cura slicer program. One day, during the printing, the power cord of the heating table was disconnected from the connection point, but the printer continued to print until we noticed the situation. The table was cold and the printed piece left the table. The rest of the press went wrong. We were using the printer on the computer with the repetier program. We cleaned everything and wanted to go back to the press. But there was another problem. When we connected the new print, the printer was starting to print, but the nozzle was squeezing a small amount of filament. The filament is not holding onto the table. The flow level was not good. But manually, when we extrude the filament, the nozzle smoothly flows the filament. When we went to press, filament could not flow in the desired amount. We struggled to solve this, we changed the nozzle several times, changed the heater aluminum block, changed the nozzle heater, removed the filament pusher motor, checked and changed the gear, but we could not be successful. We changed the slicer program we used, experimented with different computers, changed our usb memory, we could not overcome this problem. After working around for days, we re-adjusted the filament diameter to 1.40mm and the flow rate to 150% in the Cura program. This time the printing was successful. However, we are uncomfortable with this situation. Why are we experiencing this problem, what is the solution, please help. Thanks in advance.

Hi Samuel, i owned a A5 and recently changed its motherboard to a MKS GEN 1.4 because the previous one was spoilt. However when i tried to flash the custom firmware today, an error saying "unknown motherboard value set in config.h" prompt out. I did changed the motherboard in config.h to suit my gen 1.4 board). So i was wondering does the custom firmware support the 1.4 board? If it does, do you have any idea why did the error prompt out? If it doesn't, should i get a different motherboard? Im quite a noob when it comes to stuff like this hence any help would be very much appreciated! :)

Hello Samuel, thank for your Work. To upload your custom firmware, printer needs to be powered on or power off? Thank you

Have you tried priting ABS with this printer yet? If you have, any warping issue and hows the print quality?

Hi Samuel, can i have the full working firmware for the JGAurora A5 from you, mine motherboard is blowup and i have to install new, i am sure you are the specialist for this, i try already the one in the jgaurorawiki buth there is no full size ready that is working without error, i like the one like i buy my printer, i hope you can help me and many other with this issue, thanks.

is the jgaurora A5S compatible with macbook?

Hi , is there any way around to customize the inkjet printer firmware ..

does this work with the a5s aswell?

When i try to compile or update i get error message Custom Marlin Firmware 1.1.8C\Marlin\Marlin.ino:45:110: fatal error: U8glib.h: No such file or directory #include // library for graphics LCD by Oli Kraus (github.com/olikraus/U8glib_Arduino) never done things like that before so i feel like im in dark forest.

Hi Samuel. I just received my A5 and successfully flashed the custom firmware like you showed and everything went smoothly thanks! But I just noticed that my extruder fan is always on. Is the firmware configured like that or am I missing a setting somewhere?

Hi Samuel... first of all thanks for the video... as a content creator myself I know how long it takes to make a video... My A5 loves to layer shift on large Gcode files... do you think this upgrade could solve this issue?!? Thanks again and best regards from Brazil!!!

Hello all! I bought another JGAurora A5. It came with the reworked build plate and updated firmware. I flashed the custom firmware following you latest instruction and all appeared to go smooth until I tried using the printer. The Z axis would only move up, Y axis would only move in one direction and X axis would not move. Homing would not work as well. Only moved up on the Z axis. I flashed the A5 original firmware and all worked well. I tried 2 more times with the same results. I'm back to the A5 original firmware, which I really don't like. It homes right onto the build plate! Is it possible that JGAurora has somehow prevented flashing custom firmware? Any ideas would be appreciated. Tom

Thanks a lot for the video ! For some reason, the .ino file with the custom firmware cannot be downloaded. Any other link? Thanks & regards.

I have the A5S and a mac, how do i go about getting the custom firmware installed? Thanks

Hey do you know how I can see what port the thing is in on a Mac

Hello, Samuel! can I do this procedure with A3S?

HI every time arduino shows me this error :Arduino: 1.8.5 (Windows Store 1.8.10.0) (Windows 10), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)" C:\Users\Florian\AppData\Local\Temp\Temp1_JGAurora A5 Custom Main Marlin Firmware 1.1.8C (3).zip\JGAurora A5 - Custom Marlin Firmware 1.1.8C\Marlin\Marlin.ino:31:26: fatal error: MarlinConfig.h: No such file or directory #include "MarlinConfig.h" ^ compilation terminated. exit status 1

Will thisi firmware work on the A5S? Specifically for mesh leveling...

Hıı how to install with sd card without marlin please help 🙏

Hello!! May I use Arduino Uno?

great video, might want to say "um" less though, more for presentation then anything. thanks! Look forward to future vids

you took wayyyyyyyyyyyy too long to get to the "meat"

How hard is it to mic your video properly? Seriously? My god. All these videos of people you can't hear them at all. Why post crap?
