Error compiling board for board Arduino Mega or Arduino Mega 2560

Good evening, I keep getting this error while trying to very a sketch for my CR10S printer. I’ve downloaded the library and board files but error still continues.

Arduino error.txt (184 KB)

The most relevant parts of @lwarnell01's Arduino error.txt:

Error compiling for board Arduino Mega or Mega 2560.

Note that I think the output has been mixed up a bit by the Arduino IDE (I believe this is an unfortunate side effect of arduino-builder's multithreading capability).
