Afinibot A2 delta 3D printer firmware update

Hi,

I tried to update the firmware on my A2 because the printer started to behave very oddly (filling outside the shape, printing in the air, etc).
I opened the folder ** provided on the SD card.** Then I opened the .ino file named and uploaded to the printer using the Arduino IDE.

Now, it is not the same firmware (“UM v2.4”) as what was originally installed (Repetier something I think). The printer doesn’t detect the endstops and crashes on all 3 limit switches…
I looked in the “supported motherboards” list in the Configuration.h file but didn’t know what to choose other than 33 (RAMPS 1.3 / 1.4 ), which is the default model.
Cura can’t even load the Firmare Configuration, even with baudrate on AUTO.

My questions are:

  1. How do I get back to the original firmware (or any working one)

  2. Why would the printer start to print so oddly for no obvious reason?

  3. Am I the only one who bought the A2? I can’t find any support on youtube /google

Any help would be greatly appreciated!

Thanks!

Ok so I don’t know how but I found Micromake’s Google Drive, which has the Repetier firmware : drive.google.com/open?id=0B1DQU … U5rNDB1YVE

I conclude that the firmwake on the SD card provided is not the one we should use…or at least Repetier works better.

When I finally reinstalled Repetier, the compiler showed a warning saying that there was little memory left in the uC, which I believe led to the printing instability I have seen.
I did a small print to test if the reinstall helped and so far, the print was perfect.

Looks like I solved all my problems haha!
I hope this can help someone else though!
