Configuring 12864 LCD on Maestro?

Agniusm

Adding SD card to the LCD is no go. You can add it as a separate module you can get on ebay for few quid:
Just for illustration:

I have attached somewhat fixed basic menu few posts above

Looks like vcc, gnd, buzz and enc_sw will work on exp1, you only need to cut slot in lcd connector and flip ribbon cable?! I will try that.
Another way is just to cut ribbon cable and crimp dupont pins, then use connectors found on pc for power,hdd, reset. They come in multiple sizes and could be salvaged

I just filed off the bit on the cable connector that indexes the cable. Less than a minute and I didn't butcher the board

@3dmntbighker I know, but its just easier to nip the slot out with snips

If I want your opinion I'll tell you what it is

Are the menu files that M3D ships on the Maestro available zipped somewhere? My SD card bit the dust today, and I had no backup. Yeah, so a backup admin for NASA had no backup. Ughhh. I got the ones agniusm linked, but I'd like the original ones, or for that matter a zip file of the entire SD card. All I could find was the generic one without the menu directory.

I've put a copy on the ones that came on my Crane at https://www.dropbox.com/s/f6jthzr7vh8619g/MenuFiles.zip?dl=0. They may not be up to date, and they could almost certainly be simplified.

Thanks bro

I'm tired of waiting support in the duet for this lcd, buy 2 maestro to enjoy a simple lcd on my printers

@cata, the Duet WiFi and Ethernet do not have the hardware needed to level shift the LCD signals to 5V and gate the SPI clock for compatibility with common 12864 LCD/encoder combos. That's the main reason why the firmware builds for those boards don't include the 12864 support.

Cata

@dc42 a level shifter is too basic to implement, not the same with the firm support. Why not implement in the firm and let the users works with the level shifter?

considering you need an adapter for the ramps to connect an lcd this would not be much different

Is anyone working on the print from SD card functions? It seems like the most glaring thing that's missing from what ships with a Maestro. I'm fully aware that this a back burner project for the devs.

@3dmntbighker
not sure what you mean.
the files uploaded to the maestro are stored on the sd card. you can select those and print them.
also you can select them from the lcd and print them

My Maestro SD card failed a week ago. It arrived with a non-functional set of menu files for the 12864. I don't recall seeing any gcode models on the card out of the box either. I managed to get some portion of the menu to work between firmware updates and doing some editing. DC42 sent me the Crane files he had to get me functional again, but the stuff for navigating the card and printing has not worked for me so far since the card failure. I got a missing file error. I'll look it over again when the printer isn't busy.

edit: For whatever reason it failed yesterday and it works now? Go figure.

Hi,

just received my Maestro board and took the 12684 lcd from my ramps board.
After powering the Maestro the lcd shows just a blue screen
I have setup the "main" file with just the follwing line

text R0 C0 F1 T"My 3D Printer "

I tried upgrading the firmware to the latest , but the lcd is still not working.
Is there anything i i'll have to do to make it work?
