External SD Card not Reading (Maestro with 12864 Display)

Phaedrux

Is there any indication of what the pinout is on the silk screen of the PCB?

Unfortunately, there's none whatsoever. It did come with an adapter for using it with a ramps board though, and that seems to be the same as the official adapter as far as I can tell.

There isn't any configuration to do for the external SD card, it should just work assuming that you have plugged both ribbon cables into the correct 2 ports of the Maestro. If both the LCD and the rotary encoder are working then you've got that right.

Before you send the LCD unit back, let me test that the external SD card support still works in RRF 3.02-RC2 for the Maestro, because it's been a while since I tested it.

I can't get the external SD card working on my 12864 LCD either, so it's probably a firmware bug. If so, you reported this just in time for me to fix it in 3.01-RC3.

Confirmed, it's a firmware bug in the RepRapFirmware 3 series for the Maestro. Now fixed in 3.01-RC3, which I hope to release later today.

David, thanks very much for your time, investigation, and quick response! I really appreciate it, and I've never found a company with service that even compares to yours!

Thanks for the quick fix! When you release the update, I'll test it and be sure to get back with you.

I can confirm that the external SD card works perfectly with the new firmware version. Thanks!

@dc42 Hi David,

Ive just got my Maestro Zaribo built...and facing t he same issue. I'm on 3.1.1

12864 rotary encode is working and can use the screen fully. SD card on the screen is working from DWC 3.1.1 but not from the 12864

Thoughts?

Many thanks

Probably best if you start your own thread.
