2.1.2.3 build 1

!!! 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:
https://github.com/Hummtaro/Elegoo-Neptune-screen/releases

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.

Let me know if you find any bugs. :)

2.1.2.3 build for testing

!!! THIS IS STILL WORK IN PROGRESS AND PRETTY MUCH UNTESTED - USE AT OWN RISK !!!

Another test build of my custom firmware for the Elegoo Neptune 3 Pro.

This version is still based on Elegoo 1.1.5.1b but updated to the latest Marlin 2.1.2.3.
Uses the same values for input shaping and linear advance as dderg's fork (https://github.com/dderg/Marlin-Neptune-3-Pro)

2.1.2 build for testing

!!! THIS IS STILL WORK IN PROGRESS AND PRETTY MUCH UNTESTED - USE AT OWN RISK !!!

Second build of my custom firmware for the Elegoo Neptune 3 Pro.

This version is based on the original Marlin sources of v2.1.2 (see https://github.com/MarlinFirmware/Marlin) with the modifications made and published by Elegoo for v1.1.5.1b (see https://github.com/NARUTOfzr/Elegoo-Neptune-marlin2.1.1) merged into it.
Uses the same values for input shaping and linear advance as dderg's fork (https://github.com/dderg/Marlin-Neptune-3-Pro)

Therefore this should work similar to dderg's build in terms of print quality but with the goodies of the newer elegoo source added.

2.1.1 build for testing

!!! THIS IS STILL WORK IN PROGRESS AND PRETTY MUCH UNTESTED - USE AT OWN RISK !!!

Initial build of my custom firmware for the Elegoo Neptune 3 Pro.

This version is based on the original Marlin sources of v2.1.1 (see https://github.com/MarlinFirmware/Marlin) with the modifications made and published by Elegoo for v1.1.5.1b (see https://github.com/NARUTOfzr/Elegoo-Neptune-marlin2.1.1) merged into it.

Therefore this build should be functional identical to the official Elegoo release v1.1.5.1b (see https://github.com/NARUTOfzr/Neptune_3_Pro_Plus_Max).
