Up-to-date Marlin firmware for the Aurora A5

by mgilardi

Hi all,

Stay tuned for more A5 firmware updates, we are actively working to get this open source. Currently working on getting the filament sensor to unload and load as expected.

I love feedback and collaboration, so please feel free to help it along!

https://github.com/GilardiLabs/Marlin/tree/JGAurora-A5

EDIT: We've released a solid firmware. See link above.

***NOTE: Please make sure to have a backup of your firmware (or JG's original HEX file) before proceeding with this. I take no responsibility for errors or issues, though I am here to help if I can. :)

JG Aurora A5 with Marlin 2.0?

by DJGummikuh

Hello! I just did the endeavour to get my A5 on Marlin 2.0 Firmware in the process of trying to get my print quality back up again.

It seems like it is working fine however I currently have two issues:

  • the PID autotune values are not really good, I still have up to +/- 5°C around the configured temperature for the hotend
  • I have SEVERE underextrusion, even with 120% flowrate

For the latter I already experimented around with a lot of stuff including disassembly of the hotend and checking if the PTFE is properly mounted. I could not find any reason why this is happening.

So I have two questions

  • any of you have an A5 with Marlin 2.0 running and can tell me if this is working properly?
  • Why on earth do I have these issues?

Kind regards,
Johannes

Temperature Issues

by DJGummikuh

Hello!

I have Issues with my JGAurora A5 where apparently the temperature of my hotend is ~30-40°C below what the Printer reports. This causes me to have to print PLA at 245°C (indicated) and making it impossible to print PETG since I can't exceed 250°C due to my current firmware limitations.

I suspect the thermistor to be at fault but I do not really know how to properly debug this. At room temperature, both the hotend and the build plate thermistors report within around 1% tolerance between each other, so how can it be that at higher temperatures the hotend seems to be so far off? I use a silicone sock on my hotend but the issue remains also when I remove it.

Edit: I do have a custom-fitted firmware (latest Stock firmware with adaptations for my BLTouch and hardwired defaults for the sensor offsets) but that should not be the issue as I haven't flashed for around 4 Months, however the issues developed only relatively recently (around 2 weeks ago) without any interference in the firmware.
