Alunar M508 Marlin Firmware

This is (usually) the latest Marlin firmware tweaked and tailored for the Alunar M508 3D Printer. The settings are what work for my machine, with my setup, it may not be perfect for you.

Flash Firmware From Binaries

1. Download the latest binary release.
2. Extract the zip file
3. Download Arduino IDE (if you haven't already)
   • You could also get binaries for avrdude.
4. Open console window to avrdude binary directory.
   • Windows: `c:\Program Files(x86)\Arduino\hardware\tools\avr\bin
   • Linux/macOS: /<arduino-dir>/hardware/tools/avr/bin
5. Run the following command:

$ avrdude -p m2560 -c avrispmkII -P /dev/ttyACM0 -C /<arduino-dir>/hardware/tools/avr/etc/avrdude.conf -D -U flash:w:/PATH/TO/FIRMWARE.HEX:i

/dev/ttyACM0 may not be the port that the device is connected to on your machine. On a Windows machine, this value will be something like COM4

alunar-prusa-i3-marlin-i3-firmware's Issues

Original version of alunar firmware

Hello,

Sorry to contact you this way, but I didn't find a way to contact you except via issue submission...
You mention that this is the firmware that came with your alunar prusa i3.

I have recently purchased the alunar m508... I wanted to make some modifications to enable auto leveling, but the SD card that was delivered with the package is damaged and is unreadable. So, I don't have any baseline for the firmware (don't even know what version is actually installed). So, I'm afraid to flash anything if I can't get back to the original version in case of a problem...

So, I was wondering if the version you have here would work with the m508? I see you have already brought it up to the latest marlin version. Do you also have the original version delivered on the SD card (in fact, do you have the content of the original SD card)?

I have an M508 - Had to Invert the X Axis, and my SD Card Wont work

So Im still new to this. But everything was working 100% prior to flashing. I was on the Stock Firmware that came with the 508. I had to Invert the x-axis. But for the Life Of me I cannot figure out how to get the SD-card to read. Most folks tell me its my card. but ive double and triple checked.. and it all worked before I flashed over with marlin.

Now I do have the Newer control board. its the HY-Base-L 1.0, to my understanding they changed the boards out recently maybe in the past year?

Any help or suggestions would be appreciated. I would reflash to Stock, but I cant find the Stock 508 Firmware anywhere. the folder on the SD card Alunar sent was toast on delivery. and Im sure it was on there.
