Anycubic i3 Mega / Mega-S Marlin 1.1.9 by davidramiro adapted to RepRapDiscount full graphics display

Forked from Anycubic i3 Mega / Mega-S Marlin 1.1.9 by davidramiro

Changes

• Anycubic TFT display disabled
• RepRapDiscount full graphics enabled
• SPI delay adjusted for clone with long cables
• Serial buffers adjusted for lesser memory usage
• M73 R support, displayed instead of X and Y cordinates
• Manual level corners (moves from corner to corner)
• Skew correction with gcode
• File sorting with RAM cache -> fast file list scrolling

Still works

• Filament sensor
• Manual mesh bed levelling, but a lot easier with "standard" display

Bugs

• Still no power out resume

Connection

See connection board image posted by General5X

See Trigorilla connections posted by misterbig

RepRap display J2 goes to Trigorilla EXP1

RepRap display J3 goes to Trigorilla EXP2

Connection board connector HUB is connected (it seems to be 2mm raster, I didn't have dupont wires for that :/ )

Connection board pins PIN_19 .. PIN_3 are wired to Trigorilla limit switches D19 .. D3

Connection board pins PIN_GROUND and PIN_A13 are wired to Trigorilla Temp sensors GDN and A13 (nozzle temp sensor)

Make sure not to take out connectors in A14 and AUX. Some are hot glued to connection board.

After that build Marlin, update firmware with Marlin.ino.mega.hex (never the one with bootloader!) and see if it works ;)

Changes by davidramiro:

• Thermal runaway protection thresholds tweaked
• Manual mesh bed leveling enabled (check this link to learn more about it)
• Heatbed PID mode enabled
• TMC2208 configured in standalone mode
• Stepper orientation flipped (you don't have to flip the connectors on the board anymore)
• Linear advance unlocked (Off by default. Research, calibrate and then enable with M900 Kx)
• S-Curve Acceleration enabled
• G26 Mesh Validation enabled
• Some redundant code removed to save memory
• Minor tweaks on default jerk and acceleration
• Print statistics enabled (send M78 to read them)
• M600 filament change feature enabled
  • Implemented easy resume via display
• Filament runout behaviour tweaked
  • Added purge and retract
  • Move nozzle to park position on runout
  • Prevent false positives by adding a small delay to the sensor
• Pause and stop behaviour tweaked
• Added M888 cooldown routine for the Anycubic Ultrabase

Changes by derhopp:

• 12V capability on FAN0 (parts cooling fan) enabled
• Buzzer disabled (e.g. startup beep)
• Subdirectory support: Press the round arrow after selecting a directory
• Special menu in the SD file menu: Press the round arrow after selecting Special menu
