!!! THIS IS STILL WORK IN PROGRESS AND PRETTY MUCH UNTESTED - USE AT OWN RISK !!!
The first build i actually use on my printer. Still only barely tested and only on N3Pro tho.
Based on:
Official Marlin 2.1.2.3: https://github.com/MarlinFirmware/Marlin/tree/2.1.2.3
Elegoo's fork 1.x.5.1b: https://github.com/NARUTOfzr/Elegoo-Neptune-marlin2.1.1/tree/9631b7f5eb60b9c94fca12384662718f3b1ef060
sroemer's fork: https://github.com/sroemer/marlin-neptune3pro
dderg's fork: https://github.com/dderg/Marlin-Neptune-3-Pro
tbreuer's fork: https://github.com/tbreuer/Elegoo-Neptune-marlin2.1.2
Changes:
- Enabled double probing for better bed level accuracy. (goes from +-0.1 to +-0.01 for my printer)
- Enabled M48 to test probe accuracy
- Raised probing speed (values taken from tbreuer's fork)
- Raised max noozle temperature up to 350°C. Be careful folks! Only use temperatures your hotend can handle! Stock hotend = 260°C max.
- Raised max bed temperature up to 140°C. Same as above. I'm not responsible if you break your printer or burn your house.
To be able to input temperature such high via the touch screen, see my modified screen firmware:

To flash the update, put the file on your SD card, rename it to ZNP_ROBIN_NANO.bin and start the printer with the card in.
