Update Marlin Firmware of Anycubic Kossel Pulley

Current Environment

• TriGorilla Board, based on AtMega 2560
• Marlin 2.1.2.1, self compiled for RGBW- and Servo0 support
• First Run:
  • Erase EEPROM settings
  • Set Z-Probe: -15.6 (new hotend)
  • Config/Delta Kalib/Auto Kalib
  • Check: Manual (careful!) move to Z = 0, X=+-90, Y=+-90
    • since rod change only ok for XY +-70, outside head goes down!

Parameters

• Latest Marlin (2.0.5.3)
• PlatformIO 4.3.4
• OpenSuse 15.1

Documentation

• https://marlinfw.org/docs/basics/install.html
• https://marlinfw.org/docs/basics/install_platformio.html
• https://marlinfw.org/docs/basics/install_platformio_vscode.html

Edit in platformio.ini or avr.ini (since 2.1?)

Since my notebook has more than one usb serial port, I needed to tell platformio which one connects to the printer:

[env:mega2560]
...
upload_port = /dev/ttyUSB1
