updated Marlin firmware config for RepRapGuru printer kit
The RepRapGuru 3d printer kit refers to an older version of the Marlin firmware (1.1.4), so I've ported their parameters to Marlin 1.1.9 and taken a diff to make it easier to see just the changes.
The Configuration.h and Configuration_adv.h here should drop right over the stock Marlin 1.1.9 files, like those provided as configuration examples. The diff files are informational; if you don't know what they are you can safely ignore them.
Settings to change for your printer:
PIDTEMPBED: I'm using this feature with a seperate MOSFET board, the original RRG configuration had it switched off. I had no issue using PWM without a seperate MOSFET, but there's reasons not to.
DEFAULT_K(p,i,d): the default PID tuning parameters are set for my printer, you should be doing PID Autotune and adjusting those for your printer anyway, so the compiled in numbers aren't terribly critical.
