Adjusted some settings to stabilize serial connection to OctoPrint:

• Baud rate now 11520 (adjust your octoprint/pronterface connection)
• enabled RX/TX buffer
• resend wait signal, when RX runs empty

Notes:

• EEPROM is currently saved on SD-card! To keep your settings, make sure you have a SD card inserted on startup and when making changes.
• The Robin Nano has an on-board AT24c16 EEPROM, but I have no experience how to address stuff over I²C and no way to debug properly.
• Linear Advance is activated, but set to 0. If you want to use it you activate it with "M900 K" (see http://marlinfw.org/docs/features/lin_advance.html)
• Junction deviation is deactivated in this release
• don't forget, that some bootloader versions require to rename the .bin to "Robin_nano35.bin"

This is a precompiled firmware file!
use at own risk

• condensed config files for easier setup
• default filament load length set to 0
• default K-Value 0
• more safe homing procedure
• no filament runout yet
• no mesh bed leveling

1.1.8 Marlin with my config files for the anycubic 4MAX with a Titan aero update.

• use at own risk - double check all changes for yourself!
• !! I changed the stepper drivers on X/Y/E0, directions are inverted now.

Changed:

• bootscreen
• LCD encoder direction
• some acc/jerk settings
• PID values for Titan Aero Hotend (PLA and PETG inside config)
• stepper directions according to my driver/extruder setup
• bedsize and offset values
• E3D hotend thermistor
• uses RAMPS 1.4 EFB template
• preheat temperatures to my prefs

Enabled options:

• manual mesh bed leveling
• corner bed leveling procedure
• cooling fan kickstart and mininum PWN value
• babystepping option
• rehome after power down (my Z axis drops without power)

Disabled options:

• filament runout sensor
