Always up-to-date Marlin firmware for the Aurora A3

by mgilardi

Hi all,

I've decided to (minimally) maintain an Aurora A3 branch of the Marlin 1.1.x firmware. I will keep it as current as possible with 1.1.x releases.

Link to the repository: https://github.com/GilardiLabs/Marlin/tree/JGAurora-A3

Disclaimer: The link to the repository may change over time - be sure to take note. MAKE SURE TO MAKE A BACKUP OF YOUR CURRENT FIRMWARE PRIOR TO UPLOADING -- I DO NOT TAKE ANY RESPONSIBILITY FOR ISSUES/ERRORS, though I am here to help. :)

The settings in Configuration.h should work out-of-the-box, but here are some variables I recommend customizing for your preferences:

  • CUSTOM_MACHINE_NAME (self explanatory)
  • DEFAULT_Kp, DEFAULT_Ki, DEFAULT_Kd (custom PID tune)
  • MESH_BED_LEVELING (currently on, but you may prefer to manually level, or have auto leveling)
  • ULTRA_LCD (vs DOGLCD, depending on your LCD setup - it doesn't hurt, but this is actually irrelevant in most cases, as long as you select an LCD type, such as RepRap Discount Controller, etc)

X-Axis Problem

by Stopsign

I'm fairly new to 3d printing, and have a stock JG Aurora A3. All the sudden the X Axis doesn't want to move. It just sits there, and sounds like something is grinding. Anyone have any ideas on what is going on? I tried to upload a video showing what it's doing, but it won't attach for some reason.

UGH, my extruder controller chip went

by DrBlackross

I've just converted it to a bowden (worked great for 3 prints) then the extruder controller on the PCB went, is there somewhere on amazon i can find a controller board?

i figured it was going since it would act like it clogged or ran out of filament, which it didn't. But like i said i did get to print 3 successful prints (good size) before it went.

(with my eyes i cant resolder or replace the chip, lol)
